Design of Grid-forming Synchronous Condenser System for Nagqu and Ngari Power Grids in Xizang Autonomous Region
摘要
Abstract
After the Xizang power grid was interconnected with the Northwest and Southwest power grids,an AC-DC parallel pattern and a long-chain weak AC connection were formed,making voltage control difficult.The distribution of power sources and loads within the grid is uneven,and the load centers lack power source support.With the growth of load,the problem of unstable voltage in the central Xizang power grid after faults at important sections within the grid has become prominent.This paper conducts an in-depth analysis of the impact of load growth in the central Xizang region on the voltage stability of the Xizang power grid.It proposes a system design scheme to configure grid-forming synchronous condensers in the Nagqu and Ngari regions,addressing voltage instability caused by insufficient reactive power support in the central Xizang power grid.They can also provide active power support after grid faults and serve as a transitional and supplementary measure for power supply failures in the Nagqu and Ngari regional power grids.Simulation calculations were carried out to verify that the grid-forming SVG can provide reactive power support and short-term active power output to the system during grid faults.After the operation of the grid-forming static synchronous condensers in the Nagqu and Ngari power grids,they have provided reactive and active power support for the stable operation of the power grid.关键词
