由于动态无功补偿能力不足,受端电网有可能会面临暂态电压稳定问题。本文在介绍动态无功补偿装置STATCOM的工作原理和模型基础上,以北京电网2011年网架结构为背景开展了静止无功补偿器(STATCOM)在北京电网中的应用仿真,论证了STATCOM对电网暂态电压的动态支撑作用。通过对其安装效果进行仿真计算和分析比较,提出了STATCOM在电网暂态电压稳定中的应用建议。
Due to the lack of dynamic reactive power compensation, the power grid may be subject to transient voltage stability issues. Based on the working principle and model of dynamic reactive power compensation device STATCOM, the application simulation of static var compensator (STATCOM) in Beijing power grid is carried out under the background of the grid structure of Beijing power grid in 2011, Transient voltage dynamic support function. Through the simulation calculation and analysis of its installation effect, the application of STATCOM in the transient voltage stability of power network is proposed.
