摘要
从多馈入直流系统稳定性分析理论出发,延伸得出多送出特高压交直流背景下电网外送电能力分析方法。其中,由多馈入短路比指标延伸得出多送出短路比指标,通过设定多送出短路比指标求得电网此时的外送电能力,再利用BPA仿真平台进行稳定性分析,根据分析结果对多送出短路比指标进行不断修正,调整外送电容量直至多送出短路比指标达到设定值,最终得出电网的外送电能力,为建设特高压直流线路提供意见和建议。
Based on the stability analysis theory of multi-infeed high voltage direct current （HVDC） system, the transmission capacity analysis method of multi-send ultra high voltage （UHV） AC/DC power grid is studied in this paper. By extending the multi-infeed short circuit ratio index, we can get the multi-send short circuit ratio index （MS- SCR）. The present outward transmission capacity of the power grid is obtained by setting the MSSCR, and then the stability of the system is analyzed by using BPA simulation platform. The MSSCR is revised according to the analysis results, and adjust the outward transmission capacity until MSSCR reaches the set value, which is the final outward transmission capacity of the grid, and provides opinions and suggestions for the construction ofUHV DC lines.
