SVG配置容量对LCC换相失败抵御能力仿真研究
Simulation Study on the Ability of SVG Configuration Capacity to Resist LCC Commutation Failure
摘要
Abstract
Line commutated capacitor high-voltage direct current(LCC-HVDC)is an important technical form of high-voltage direct current transmission.Since the converter valve was composed of semi-controlled device thyristors,the commutation failure of the inverter-side converter station has become a key issue affecting the normal and safe operation of LCC.Configuring static var generator(SVG)for reactive power compensation can effectively improve the converter station's ability to resist commutation failure.The influence of SVG reactive power compensation was discussed on LCC commutation failure from a mechanism perspective,and simulation verification was conducted.First,the mathematical model of LCC was established and the mechanism of commutation failure was analyzed.Secondly,the influence of SVG reactive power compensation on the commutation failure process was analyzed.Finally,the model was built in Simulink for simulation verification.关键词
