摘要
广东电网异步联网模式分割了交流网络规模,对电网电压稳定性造成影响。为保证系统的电压稳定性,结合广东电网实际情况和静止同步补偿器(static synchronous compensator,STATCOM)建设条件,对分网后的电压薄弱点进行STATCOM优化配置分析,归纳出STATCOM配置在提升广东电网电压稳定性的效果,提出适用于广东电网的STATCOM配置的推荐方案,并对推荐方案进行效果分析。结果表明:广东电网采用柔性直流东西部分网后,电压稳定裕度下降,交流故障对直流的影响更明显;同时验证了推荐STATCOM配置方案对提升系统电压稳定性效果明显,且在经济技术上可行。
Asynchronous networking mode of Guangdong power grid divided scale of AC network which had affected voltage stability of the grid. In order to ensure voltage stability, this paper analyzes optimizing configuration of static synchronous compensator （STATCOM） for voltage vulnerabilities after grid division by combining actual situation of Guangdong power grid and construction conditions for STATCOM. It summarizes effects of STATCOM promoting voltage stability, presents a recommended proposal suitable for STATCOM configuration in Guangdong power grid and analyzes effect of this proposal. The results indicate after adopting flexible DC for the western and eastern grid division, voltage stability margin of Guang-dong power grid has decreased and AC faults have more significant effect on DC. Meanwhile, it verifies effectiveness of the recommended proposal in promoting voltage stability and feasibility in economic technique.
