  Recently, No. 1, 2, and 3 compensators of the Qinghai province Hainan state ±800 kV converter station, undertaken by Energy China TEPC, were integrated into the Qinghai Power Grid and entered a 168-hour trial operation. This is the first set of grid-connected and trial-operation compensator on the Qinghai-Tibet Plateau. When officially put into operation, it shall provide powerful support for the strong and stable operation of the Qinghai UHV backbone grid and the delivery of new energy.
  The Qinghai province Hainan state ±800 kV converter station project is the first UHV transmission channel in Qinghai Province and the highest UHV converter station in China. Energy China TEPC is responsible for Lot A including the civil construction and the erection of the building steel structure of the commutation area, AC field and DC field, and for Lot D including the civil construction, equipment erection, and single debugging of the compensator area.
  It is reported that the Qinghai-Henan ±800 kV UHV DC project starts at the Hainan state ±800 kV converter station in Qinghai province and ends at the Zhumadian converter station in Henan Province, passing through four provinces, including Qinghai, Gansu, Shaanxi and Henan, with a total length of about 1577.5 kilometers. It adopts single-circuit bipolar erection, and the project is completely independent of itself clean energy. It is the first practice in the world to use large DC transmission technology to bundle wind, light, hydro-power and other clean energy for long-distance transmission.
  As the world's first UHV artery specially built for clean energy delivery, the successful electrification of the Qinghai province Hainan state ±800kV converter station shall give full play to the advantages of Qinghai Province's clean energy and effectively promote the consumption of clean electricity in the western region. It is significant for the promotion of Qinghai’s poverty-alleviation and Henan’s energy transformation and atmospheric pollution control.
