摘　　要：主要从并联补偿技术(Parallel compensation technology)改变电网的阻抗特性、维持或控制节点电压、向电网注入或吸收无功/有功功率三个作用出发,采用临界稳定分析方法(Critical stability analysis),对没有和已有并联补偿的系统进行分析比较,证明并联补偿能够提高输电系统电压稳定性,对改善电网安全稳定运行,具有重要的作用.The three major roles of parallel compensation technology are studied, which are, changing the impedance characteristics of the power grid; maintaining or controlling node voltage; injecting or absorbing reactive power or active power to the grid. By using the critical stability analysis method, the systems with parallel compensation are compared with those without parallel compensation. It is proved that parallel compensation can improve the voltage stability of transmission system, which has an important role to improve the grid＇s security and stability operation.
