摘要
以某变电站为例,采用电力系统暂态仿真程序ATP/EMTP,对母线倒负荷引发电容器自爆的暂态过程进行仿真分析,并采取相应的措施来预防暂态电压引发电容器自爆事故。分析结果表明,不带电容器进行母线倒负荷操作,可避免电容器所接母线电压过高,防止电容器在操作过程中引发过大电流而发生自爆危险。
Taking a substation as an example, the power system transient simulation program ATP / EMTP was used to simulate the transient process of self-explosion of capacitor group caused by the rearrangement operation of bus load. The corresponding measures were taken to prevent and solve the accident of capacitor self-explosion caused by transient voltage. Analysis results showed that it can avoid the over voltage of the bus and prevent over current caused by the operation of capacitors without the capacitor for by the rearrangement operation.
