【摘要】 在超高压输电线路上采用串联补偿电容可以保持系统电压稳定 ,提高电力系统的稳定性 ,由于电容的安装地点不同 ,将对零序功率方向继电器正确动作产生很大影响 ,由此我们必须从理论上认真分析并寻找其克服方法 ,以保证零序功率方向继电器的正确动作。更多还原

【Abstract】 Can keep the systematic voltage steady to compensate the electric capacity to adopt contacting on the supervoltage transmission line of electricity, improve the stability of the power system, because the installation site of the electric capacity is different, will produce very great influence on correct movements of direction relay of the power of zero preface, therefore we must analyse and look for theoretically conscientiously it overcomes the method , so as to ensure correct movements of the zero preface direction relay of power.更多还原
