A power engineer snowstorm memory: the responsibility of the College Entrance Examination frozen
line repair and get the building site. 0:25, Hunan Chenzhou Power finally reopened the main network in Hunan Power Grid and contact Tong - Tong River - Chengqianling 220KV lines, frozen to restore power within the city of Chenzhou City!
1 day thousands of fighting hard and get the building repair and support members of anti-ice protection network in Hunan People's Armed Police officers and men, from various points surrounding the construction together, while applauding, cheering loudly!
snow, everyone's hair is the rain wet snow, ice, sorrows and joys of dozens of tightly huddled man. rescue heroes in the wilderness around the red fire, more than 20 days, and finally eat the dinner that steaming Dayton.
Hunan Electric Power Company, deputy chief engineer Dai Qinghua in the snow, a toast to you. In this million reunion, his glass held high, looking upward, try to drink. And then he drank a toast to the group after group came to the repair team members bowed, with eyes full of tears.
moment of triumph finally came, but Dai Qinghua mood was always difficult to calm. from January 11, 2008 start in 50 years of snow rushing southern China.
in Hunan, the continuous rising of frozen snow to the central part of the province of the sudden slowdown in the pace of a rare snowstorm to Hunan road, railway line was blocked, resulting in poor transport coal, electricity in many regions and cities tension, freezing rain mixed with snow, a test of Hunan Power Grid.
Hunan power grid as a whole still bloodshot.
in Dai Qinghua mind, he is in fact no different to any power emergency team members. In the days of Chenzhou, he braved the biting cold wind, climbing over the top laden with ice. whirring north wind, blowing his keep my eyes open, in less than 0.2 meters wide mountain road, often on the left is a cliff on the right is the cliff, are often neglected from time to time occur. Under his guidance, the treatment is usually a good point of failure , had a chance to rest, is again non-stop, and went to another point of failure.
Dai Qinghua memories: days in Chenzhou, 7-8 degrees below zero outside, ice and snow, biting wind, bringing the drinks are iced hh away from the city's rescue scene: hungry, only taking the time to chew a hard instant noodles to the ice difficult to chew.
***** the whole territory of Hunan Chenzhou is essential to restore power
The worst snowstorm in the city.
1 30, Chenzhou city by the only remaining power passage due to a back down the tower (pole) forced outage, Chenzhou city full power.
Hunan Electric Power Company Anti-ice rescue headquarters immediately organized more than 2,000 repair team in the local military and police officers under the coordination of day and night repair down the tower line outage of the carp pond and other key line, open up the transmission channel of Chenzhou.
However, Ice conditions continue to deteriorate, January 31, Chenzhou will again hit the fourth storm, resulting in a new inverted tower (pole) disconnected, the power and get the building once again seriously impeded the progress of repairs.
To support Chenzhou grid, national grid Companies from Shandong, Shanxi, Henan, Gansu, Jilin and other companies have mobilized more than 3,000 assistance team. Hunan provincial government troops and armed police were organized more than 1,100 troops, from the Hunan Electric Power Company and other Electric Power Bureau construction unit deployment of more than 2100, the focus spot, and get the building repairs in Chenzhou grid.
get the building into repair of Chenzhou's power grid at all levels to reach 1.27 million, more than 200 various construction vehicles. The main construction teams are operating 24-hour shift .
by the full repair, the surrounding area and part of the city of Chenzhou previously Xiaodongjiang by Lei Jiang and 110KV transmission network 3, but the ice storm damage is too severe, then 3 times 3 times a power trip. < br> 2008 年 2 月 6 日 零时 25 points, finally restored power supply in Chenzhou City! face in 50 years of blizzards, Hunan Electric Power achieved the final victory, but Dai Qinghua fell into a deep thought: Hunan weakness in the snow filling power, with the end of the Spring Festival, electricity consumption will gradually increase. Electric will usher in a new round of tests.
power in the ice storm of 2008 self-help process, the Hunan Power Grid made a more significant results. Dai Qinghua to correspondents, currently the basic restore power throughout Hunan. Chenzhou more than 95% of the national grid has resumed running, gradually resume power supply in Chenzhou City.
Hunan Electric Power will be February 16 basically completed at Chenzhou Power 220KV, 110KV dual power supply, the end of February to complete the basic network of sound Hunan Power Grid is expected to end on March 20 in Hunan Province's power grid of basic repair work.
Hunan, the Hunan Power drive us greatly increased confidence enough! ** in need of assistance
2007, Hunan had in the past hydropower, thermal power, purchased power at the same time an emergency situation. Daiqing Hua told the reporter, in response to the issue of power shortage, Hunan have been learned: 2003 In the summer, Changsha, Hunan, once cities in the country one of the most serious electricity shortage.
recalled more than one month ago, the Hunan power load has more than 40%, electricity emergency! severe ice storm, once the Hunan 500KV lines trip 20 times, 500KV power line 14, 220KV line trip 18 times, the line outage 8, 500KV Substation stop three.
the snow, Hunan, lost 16 billion in electricity!
2008 on January 28, Hunan Provincial Government issued an emergency , Hunan grid load was reduced to 6.8 million kilowatts, equivalent to previous years, but only peak cold season Hunan load of 3 / 4.
present, as a manual de-icing work in Hunan, and there are many foreign aid: they came from Henan, Shandong, Shanxi, Gansu, Jilin and other provinces. even in itself affected the provinces of Jiangsu and Anhui, also sent a rescue unit.
2008 年 1 月 25 日 11 时 52 points, while in the Hunan Power Grid when in distress. Hunan Electric Power Company dispatch center received an unusual call: , boiler, turbine and other main equipment is very critical, I implore the public immediately through the 220KV line anti-jade dragon power the plant to send electricity to keep the main equipment, black start. said, Hunan and Guizhou Power Grid, respectively, belong to two different power m the National Grid and China Southern Power Grid. In the past between the two power grid, and only through Hunan, Guizhou, power purchase from the situation, but also the Guizhou Power Grid's unit, after splitting and then into the Hunan power grid, and anti-transmission has never been carried out this operation, had not been tested.
Moreover, since the days of the impact of freezing, and Lou neighboring Guizhou Power Grid - Shao - Hunan Power Grid and the main Huai Web focal part of all 500KV 220KV lines and lines have been tripping, power outages. the regional power grid and main grid connection is very weak, stable level is very low, this also had to limit some of the load. At this point if more than 200 by a km transmission line to Guizhou, abnormal, the consequences would be disastrous!
Hunan Electric Power Dispatching and Communication Bureau of the company immediately will be to the party secretary of Hunan Province, Li Jian, general manager for the briefing. Li Jian decision, the decision to overcome the difficulties, the full support of eastern Guizhou grid black start.
After intense calculation, check, Hunan Province, to develop the relevant transmission transfer programs and contingency plans for handling accidents.
11 时 54 points, operation starts.
11 时 58 points, Hunan Power Grid's > Guizhou Province Power Company led on the phone said excitedly: *** ice-breaking extreme weather network security issues into a new de-icing of power
workers in Hunan entire relief process, always perform a heroic role. Hunan Provincial Party Secretary Zhang Xiao Nianye disaster relief in the party, affectionate Hunan elders bowed to the three bow. There Yi Gong, is specifically dedicated to the rescue in power at the expense of the five martyrs.
Hunan TV opening of the first relief party song and dance show, is a group interpretation of the workers and the wind power snow fight scene, and the living death of their loved ones recover.
Dai Qinghua said that in the ice-breaking process, Hunan, select the most primitive methods of artificial de-icing. Electric launched a total of 8,000 people climbed the tower lay on the ice snow removal. in the most difficult times, remains the lowest in the Hunan Power Grid 4.2 million KV, the equivalent of the maximum load before the ice storm about 35%.
Dai Qinghua introduction to the correspondents, in northeast China, although the weather is already snow routine, but the extent of the disaster is far from the South so much.
he said, the reason is that dry weather in the north, is uniform cooling, cooling is rarely sudden. And the Northeast is freezing the main floor , little ice tower. the South under the snow, granular, very hard, and hit the windows crackled.
this snow, snow, commonly known as seed, grain weight, hit the body hurts. Snow is different from the north, snow fell on the ground most of the seeds into the water, not sediment, students will be frozen when cooled.
50 years in this case the large snow in front of the power sector in Hunan is located in the southern no more experience of many de-icing, in order to ensure that the power is not paralyzed, Hunan Power had to choose to play this : Each set foot on the tower of power workers must bear the higher occupational risks, the tower collapsed and bleeding may occur at any sacrifice.
2008 年 1 26 afternoon, Transmission and Distribution construction company workers in Hunan Province Luo Haiwen, Luo Changming IN TRADITIONAL the implementation of high-pressure de-icing operations, tower collapsed due to heroic sacrifice. Two days later, Jiahe County, Hunan, Xiao Jianhua power company workers for the fight against massive ice storm in the glory of sacrifice when the high voltage line repair .1 29, Hunan Province Cao Chenzhou Power Administration power company employees affected by the fight against massive forest ice storm in the repair unfortunately killed when high voltage lines.
Dai Qinghua of these martyrs, harbor deep feelings. He has a wish: I hope the power design experts, in the future to design a grid under extreme freezing weather deicing equipment. Thus, if we encounter similar to the blizzards of 2008, there is a way to tame nature.
he said, how to use a more scientific equipment and means, in extreme climatic conditions, protect the safety of electrical workers, more safely and effectively de-icing, is worth considering not only the new task, it is the responsibility of power engineers.
*****modernization, and becomes more and more the more vulnerable The same hard-hit Guizhou province network, learn from the Hunan Power Grid. Why is there part of the 220KV power lines in Hunan state firm?
Dai Qinghua said the freezing rain is a worldwide problem, in this ice storm, the Soviet-style 220KV line shows the 500KV line than the western style superiority.
2008 年 1 21, send Metres 500KV power line No. C57 ~ C60 and C64 tower damaged; January 23 Lou Yun 500KV Line Operation No. 196 ~ 211 bar damaged tower; January 24, Qian Ping 220KV Tower Line No. A80 ~ A84 impaired hh, frequent danger.
2008 年 2 1st, due to continued freezing, Carp River Power Plant Bridge song sent to Guangdong, a 500KV line 73 to tower 79 tower there with adoptive broken down, falling wires fell on the only existing Chenzhou City, a 220KV line pond, resulting in outages line trip.
publication This reporter learned that: 1 February 2008, there is only one of the Chenzhou, a complete line of 220KV Tong, the city is still working.
Dai Qinghua introduced, 220KV follow the blueprint of the Soviet Union, Tower relatively thick, double down up only 12 wires hanging, and now this tower abandoned the Soviet model, using the European style, design more scientific and modern, but the tower hung 24 more thick wires, and the span between the more 500KV big.
addition, 220KV can also short-circuit to melt the ice, and 500KV transmission of the current is too large wire is too thick, can not melt ice. If severe icing lines not controlled, may lead to disconnection, back bar and other serious consequences.
finance, this is only a hypothetical, experimental success can still unknown? will effectively ease the power shortage situation in Hunan.
Dai Qinghua told the reporter, to strengthen the design and once in the fight against the snow for several decades the existence of a dialectical relationship, to strengthen its design, the cost will be multiplied. such as to 30 mm or more, the cost will quadruple.
recent days led to the Ministry of Science, Hunan Electric Power, Hunan Science and Technology Department is also considering how to improve and strengthen the design of network structure.
Hunan 500KV was opened in 1986, from development to Gezhouba Changde, Zhuzhou. 500KV or development in Hunan in 2007 faster than a year, will continue to develop in the future.
Dai Qinghua call us a very interesting analogy: ice storm paralyzed the Beijing-Guangzhou line, the railway's dependence on the grid is too severe. that the Beijing-Guangzhou railway and the railway sector is rooted in the interruption of power. The original double-loop design of the electrified railway traction power supply line, because the ice disaster, but also severely damaged.
However, Railway Bureau, Ministry of Railways or a request to increase the coal transportation capacity of the tilting force, assault on an emergency power plant organizations rush to transport, to ensure that important to restore power generation plant.
Dai Qinghua said, In fact, as early as 1996, the Hunan Electric Power Company along the Electric Railway on the Beijing-Guangzhou such as Hunan, Guizhou, willow branches have carried out double the power of transformation. peacetime emergency response mechanism is not the problem, but a lot of snow to the grid increased uncertainty. Shaoguan to Zhuzhou section alone does not improve the internal combustion engine and electric power emergency system, simply can not solve the power shortage problem. He said the heavy losses over the three main Chenzhou electric traction station, other places Though there is a loss, but it is quickly restored The change, although the state has not provided official documents and to change this ratio and equipped.
****** coal essay: Hunan Power Grid's coal stocks fell to historic lows. snowstorm not occurred, there is a shortage of electricity in Hunan phenomenon.
Dai Qinghua introduction to the correspondents, in the snow before the day of electricity in Hunan, about 900 coal ton, now only five or six million tons, while the day the coal load is high, only seven or eight million tons. shortage of supply of coal, coal stocks, generally last only 10 days to 15 days.
Dai Qinghua explained: ; This is the reality of the situation in Hunan, in order to have more in Hunan is unlikely. Secretary General Li in a meeting in the Administration of Work Safety said in 2008, will continue to use three billion yuan treasury bonds has driven about two million dollars and local investment, to speed up treatment of major key coal mines for safety hazards and technological transformation, and check the previous implementation of treasury bonds to support the project as soon as play a role. This move not only to ensure the safety of mining workers, but also to ensure the normal supply of electricity. Dai Qinghua told correspondents that will help ease the tight supply of coal in Hunan .
in Hunan, coal dilemma game has is an old question.
coal shortage, leading to other energy sources in the proportion of Hunan, has been unable to rise. Hunan while living in South Africa, since ancient times, the Four Rivers big thermal power plants. These small hydropower mainly in western Hunan, southern regions. in the use of new energy sources, in Hunan Province has not yet formally put into operation the wind power station, a small, but also still under construction, while the nuclear power plant construction is still In the Dai Qinghua said. the opposition of coal and electricity in this roar of wind and snow is even more serious, the adjustment of the price system, will be the only way to resolve conflicts coal.
economist commented that, snow weather, gradually price system for active coal, electricity and a further escalation of the game the two industries, although coal prices have freedom, but still state-owned electricity prices.
when coal prices in the recent Figure profit. Although the market economy, the government has no right to intervene in coal trading, coal has also been ordered will be canceled. but there are still a lot of coal operators, in order to raise the price of coal in the winter dry season, hoarding, price and to be put, power plants, generating capacity is only reduced, rather than multi-pocket.
fear of the consumer price index (CPI) over growth, the government decided not to raise price. Dai Qinghua suggested that the state should establish a comprehensive energy management, to unify the regulatory focus on energy issues.
Dai Qinghua told the period of coal, coal to price increases, while the power companies do not want to rise, so the two sides to each other carrying the supply to the price. The second stage is during the spring, as the national power grid at the end of Hunan (Hunan, south of China Southern Power Grid, such as Guizhou) , so the transport must go through several Railway Bureau, a passenger increase of the natural reduction of cargo.
In addition, some local governments before the Spring Festival in a security, usually off a number of small private coal mines. native to some extent exacerbated tight power coal.
Dai said, the face of these challenges, Hunan, Guangdong Electric Power, as if the same system of straightening out waiting until the first attack power enterprises in the energy supply to have more initiative. So, In ice and snow to come forward for the entire national grid will be a major contribution.
