Xinhua: State Grid Tibet Electric Power Co., Ltd. introduced on December 2 that at about 22:00 on December 1, the Lhasa converter station of Qinghai Tibet DC interconnection project was installed with a dimmer, and the first phase modulation unit was officially put into operation after a series of commissioning and trial operation. This is the phase modulation unit with the highest altitude in China, which will significantly improve the voltage stability of Tibet power grid, The power supply capacity of Lhasa load center will be increased by 16% on the existing basis, and the safe and stable operation level and power supply guarantee capacity of Tibet power grid will be further improved.
The condenser is the "stabilizer" and "ballast" for the safe operation of the large power grid. It has the ability to automatically and quickly adjust the system voltage, improve the safety and stability level of the power grid and improve the power supply quality of the system. Lhasa dimmer project has a total investment of RMB 233 million, and two dimmers with - 50 Mvar to + 100 Mvar reactive power regulation capacity are installed. The project adopts the latest technology of energy Internet to realize the digitization 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 "power heavenly roads" and the completion of Tibet's unified power grid, the power demand for Tibet's economic and social development has increased rapidly, and the growth rate of power consumption in the whole society has remained the leading in China for many consecutive years, putting forward higher requirements for 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 operation and operation of the project. Next, State Grid Tibet Electric Power Co., Ltd. will continue to do a good job in the grid connection and operation of the second condenser group, so as to contribute to the power supply guarantee of Tibet power grid this winter and next spring.
