Key key water control project of the Yangtze river basin flood control system - — The three gorges and gezhouba, xiluodu and xiangjiaba power station in response to the Yangtze river into the sin for the first time in the flood, the implemented 82 units were fully open for the first time. The three gorges power station for the first time this year full open grid power, high load of 20. 82 million kilowatts.

is influenced by the upper Yangtze river basin is strong precipitation, such as three gorges power station is in for the first time since the flood crest super ManFa flow process of the flood of the Yangtze river four giant 82 units of cascade hydropower stations in the lancang river fully open for the first time this year.

the relevant person in charge of the three gorges group of reporters interface, on June 27, the Yangtze river basin flood control system critical key water control project - — The three gorges and gezhouba, xiluodu and xiangjiaba power station for smoothly in the face of the Yangtze river into the sin for the first time in the flood, the implemented 82 units for the first time open, at the same time, ensure the safety of the downstream flood control utilization of flood resources, guarantee the stability of the power supply. On June 22,

6, with the increase of the upstream inflow, xiangjiaba power station all eight sets of parallel operation, the plant output of 6 million kw ( The current grid allows large output) , eight sets of ManFa for the first time this year, than last year ManFa time 25 days ahead of schedule.

on June 26, affected by the upstream area rainfall events, the big flow reached 350 million cubic meters per second, the three gorges power station units (34 Including 2 units of 50000 mw power plant unit) Open grid generation for the first time this year, the total output of 20. 17 million kilowatts, high load of 20. 82 million kilowatts.

hubei daily reported that the three gorges power station unit fully open and hubei hydropower daihatsu, cause the area near the three gorges power evacuation pressure. In addition, the recent ongoing - central China Interregional dc lines alignment test in east China, the three gorges hydropower given face huge challenges.

central China division, said the national power grid to actively adjust the provincial electric power distribution, as given in the three gorges hydropower room, large given unscheduled in the three gorges hydropower, 187. Power balance 30000 kilowatts, ensure the entire network and the three gorges hydropower given.

three gorges group, says the floods resources are all use of the three gorges power station, before the flood water. State grid division of the central China authorities to the hubei daily said, as the Yangtze river enters the main flood, expected later in the three gorges water will increase further, the three gorges area near ac/dc channel will continue to be overloaded and conveying section running state.

other, according to the three gorges group provides data on the 1st of July 14, the three gorges reservoir flow 50000 cubic meters per second, according to the Yangtze river flood control scheduling to requirements, the three gorges project according to the control over 31000 cubic meters per second, large peak clipping 19000 cubic meters per second, flood peak 40%; On July 3, 18, has been about 3 billion cubic meters of water, avoid the headwaters of the Yangtze river flood and the middle and lower reaches of the superposition, alleviate the pressure of the middle and lower reaches of the Yangtze river flood control.

as of July 6 at 8 a. m. , affected by heavy rains, the middle and lower reaches of the Yangtze river main stream across the warning level. To reduce the pressure of the middle and lower reaches of the Yangtze river flood control, the Yangtze river water resources commission of the three gorges reservoir scheduling order, issued from July 6, 9, reduce outbound analyzed, from the original 31000 cubic meters per second, reduce to 25000 cubic meters per second.
