摘要
在常规高压直流输电控制系统中,低压限流(VDCOL)对直流输电暂态稳定及交流系统电压稳定有重要的影响。基于实时数字仿真平台(RTDS),分析VDCOL的设置参数对直流和交流系统稳定性的影响,并针对传统VDCOL特性,验证了VDCOL变斜率控制有利于系统稳定。
In conventional HVDC transmission control systems,Voltage Dependent Current Order Limit(VDCOL)has an important influence on transient stability of HVDC and voltage stability of AC system.Based on Real Time Digital Simulation platform RSCAD/RTDS,the effect of the parameters setting of VDCOL on the stability of the DC and AC system was analyzed.In view of the traditional VDCOL characteristics,the VDCOL variable slope control which was beneficial to system stability was verified.
