| 摘 要： | 国华锦界电厂串补输电系统是典型的点对网远距离大容量输电模式,由于串联补偿度较高,次同步谐振（SSR）成为威胁电网稳定和机组安全的现实问题。本文以锦界电厂串补输电系统为对象,在深入分析其SSR阻尼特性和故障风险的基础上,重点研究了基于静止无功补偿器（SVC）的次同步谐振抑制方案,采用特征值分析和电磁暂态时域仿真方法详细验算了方案的有效性。

| Abstract: | The series compensation transmission system of GUOHUA JINJIE POWER PLANT is a typical station to grid,long distance and large capacity transmission mode. Because of higher series compensation level,SSR has been practical problem which becomes threat to the power system stability and operation safety. Based on the series compensation transmission system of JINJIE POWER PLANT, this paper deeply analyses SSR damping characteristic and risk of failure, focuses on SSR suppression scheme based on SVC and checks its effectiveness with the eigenvalue analysis and the electromagnetic transient time-domain simulation. |
