my country's highest-altitude grid phase-shifting unit put into operation in Lhasa

China Energy Storage Network News: State Grid Tibet Electric Power Co., Ltd. introduced on the 2nd that at about 22:00 on December 1st, the Qinghai-Tibet DC interconnection project Lhasa converter station installed a phase-shifting project. After a series of commissioning and trial runs, the first phase-shifting unit was put into formal operation. This is the highest-altitude phase-shifting unit currently in operation in China. It will significantly improve the voltage stability level of the Tibet power grid, increase the power supply capacity of the Lhasa load center by 16% on the existing basis, and further improve the safe and stable operation level and power supply guarantee capability of the Tibet power grid.

Phase condensers are the "stabilizers" and "ballast stones" for the safe operation of large power grids. They have the ability to automatically and quickly adjust the system voltage, improve the safety and stability of the power grid, and improve the quality of system power supply. The total investment of the Lhasa phase condenser project is 233 million yuan, and two phase condensers with the ability to adjust reactive power from -50 megavar to +100 megavar will be installed. The project adopts the latest energy Internet technology and realizes the digitalization of equipment detection and the automation of unit operation and maintenance.

State Grid Tibet Electric Power Co., Ltd. said that in recent years, with the construction of four "electric highways" and the completion of Tibet's unified power grid, Tibet's economic and social development demand for electricity has grown rapidly, and the growth rate of electricity consumption in the whole society has remained the highest in China for many years, which has put higher requirements on the safe and stable operation of the power grid.

In order to ensure the safe, stable and reliable operation of the large power grid, State Grid Tibet Electric Power Co., Ltd. overcame difficulties and made every effort to ensure the smooth commissioning and operation of the project. In the next step, State Grid Tibet Electric Power Co., Ltd. will continue to do a good job in the grid connection and commissioning of the second phase-shifting unit, and contribute to the power supply guarantee of the Tibet power grid this winter and next spring.
