110kV AIS隔离开关分合操作瞬态电场的模拟实验研究
|
摘要
在空气绝缘变电站(air insulated substations,AIS)中,为了研究隔离开关分合空载母线产生的空间电磁环境对站内一次侧电子设备的影响,需要在实际变电站现场进行大量重复实验以获得空间电磁环境变化规律,但这对正常电力运维是不现实的。文中设计了可以模拟实际隔离开关操作产生的瞬态电磁场的隔离开关模拟骚扰源,利用该源对110 kV AIS隔离开关分合操作产生的电场随母线参数、隔离开关触头距离、电源容量进行研究。研究结果表明:该系统可以产生频率在0.9～2 MHz左右、强度在6～20 kV的空间瞬态电场,与现有文献报道的110 k V AIS站隔离开关操作实测瞬态电场数据相吻合。
In air insulated substations(AIS),in order to study the influence of the space electromagnetic environment generated by the disconnector operated on the no-load bus to the electronic transformer,a large number of repeated tests are required to obtain the spatial electromagnetic environment change rule.However,a large number of repeated tests in substations are forbidden.Therefore,this paper designs a simulated disturbance source system that can simulate the actual disconnector operation.The system can be used to study the law of the electric field generated by 110 k V AIS disconnector's operation with different parameters.The experimental results show that the system can generate spatial transient electric field with frequency of 0.9 MHz to 2 MHz and intensity of 6 kV to 20 kV,which is in good agreement with the measured electric field data of the 110 kV AIS station reported in the existing literature.
