500 kV变电站启动调试分析

Analysis on startup experiment of 500 kV substation

江西电网正处在由220 kV主网架向500 kV骨干网架的过渡期,500 kV变电站和线路建设飞速发展。以江西电网500 kV安源变为例,详细分析了500 kV系统启动调试过程中线路单相定相、三相充电核相、空载投切,主变充电核相及相关保护试验,低压电抗器、电容器充电耐受冲击合闸能力等项目及其目的、意义,阐述了500 kV系统启动试验方法、注意事项及应遵循的一般原则,提出了做好500 kV系统工程启动应采取的相应措施。对江西电网500 kV新设备投产调试具有一定的指导意义。

Taking Jiangxi An Yuan 500 kV substation for example, startup experiment, protection experiment of charging checking phase and switch capacity of low voltage reactor and capacitor were analyzed. Also, experimental methods, attention notice and principles were expatiated. Furthermore, measures should be taken in startup experiment of 500 kV system was put forward.
