Get To Know China's Hydropower Plants----Huangdeng Hydropower Station

 Introduction

At 00:00 on January 1, 2019, four units of Dahuabiao, Huangdeng, Wulonglong and Lidi hydropower stations with a total of 1,092,500 kilowatts were successfully put into operation. 

The four units put into operation on the same day once again refreshed the world hydropower  commissioning record of "one-day double commissioning" set by the company on July 12, 2018. 

So far, all eight units of Huangdeng and Dahuaqiao hydropower stations have been put into operation. The total installed capacity has reached 24,992,800 kilowatts, the asset size has exceeded 180 billion yuan, and the cumulative power generation has exceeded 570 billion kilowatt hours.

Geographic location.

Huangdeng Hydropower Station is located in Lanping County, Nujiang Prefecture, Yunnan Province. It is developed by dike and dam, and is the fifth stage hydropower station in the hydropower ladder development program of the upper reaches of the Lancang River in Yunnan Province from Gushui to Miaowei River, mainly for power generation.

Installed capacity.

On August 16, 2018, Unit 3 of Huangdeng Hydropower Station, constructed by Hydropower Bureau XIV, passed the 72-hour trial run in one go, and was officially handed over to the power plant and put into commercial operation. 

Upstream of Toba Hydropower Station, downstream of which is connected with Dahuaqiao  hydropower Station, the dam site is located upstream of Yingpan Town, Huangdeng Hydropower Station has an installed capacity of 1900MW (4×475MW), with a guaranteed output of 507.95MW and an annual power generation capacity of 8.629 billion kWh.

So far, the power station has achieved the nodal target of power generation of the first 3 units. Huangdeng Hydropower Station Unit 3 is in a very stable state of trial operation, achieving water filling, start-up, grid connection and 72-hour trial run successfully at one time.

 

During the trial run, the bearing tile temperature, vibration, swing and temperature of each part of the unit are better than the design requirements. 

Up to now, Unit 1, Unit 2 and Unit 3 have successfully achieved one-time start-up, passed all tests and passed 72-hour test run at one time. 

Significance.

The Huangdeng Hydropower Dam, China's tallest crushed concrete gravity dam, stands at the foot of the Bilo Mountains in Lamping Bai Pumi Autonomous County, Nujiang Lisu Autonomous Prefecture. Huangdeng Hydropower Station is the fifth level of hydropower station in the Lancang River Basin, and as the main power source for the "West-East Power Transmission" and Yunnan Province to build a world-class "green energy brand", the station has painted a picture of the Lancang River from construction to operation with the concept of green development. A poetic landscape picture.

When you go to Huangdeng Hydropower Station camp, there are some trees on both sides of the road that are surrounded by a retaining wall and enjoy "special treatment", which are rare trees left behind by the power station builders. According to the staff, terrestrial ecological demonstration park transplanted the national secondary key protection of wild plants and red hair Tsubaki, as well as part of the local narrow distribution of plants pointed leaves MuXiLan and QingXiangMu. "Pointed-leaf mignonette olive is a close relative of the Mediterranean edible oil olive, with similar value to wild rice gene conservation.

The fish lift is arranged at the tailwater mouth of the power station, using the power generation tailwater current to lure fish, using an automatic guide car to transport fish boxes, and when the dam lift finishes lifting the transfer across the dam, the fish carrier transports the fish to the reservoir rivers for release, truly automating the whole process of luring fish, catching fish, transporting fish and releasing fish. A way to pick up the steps, to Huangdeng Hydropower Station dam site downstream of the Lancang River upstream section of fish stocking station. Huangdeng Hydropower Station's artificial stocking activities are carried out once a year, and a total of 842,000 tails have been artificially released since the station was built, including 170,000 Lancang split-bellied fish and 270,000 grey split-bellied fish.
