750 kV GIS设备振荡型冲击耐压试验及仿真研究
|
摘要
现场冲击耐压试验对于保障GIS设备的安全稳定运行意义重大。在现场通常采用振荡型冲击电压来考核GIS设备的绝缘性能,依托某750 kV变电站,利用数值仿真软件ATP-EMTP对800 kV超高压GIS设备在振荡型雷电冲击波作用下的电压波形和冲击电压发生器参数进行了仿真计算,结合仿真计算结果,在现场对800 kV GIS设备的某一间隔进行了冲击耐压试验以检验设备的绝缘性能,分别进行了50%正负极性额定电压(±840 kV)下的冲击试验,75%正负极性额定电压(±1 260 kV)下的冲击试验,100%正负极性额定电压(±1 680 kV)下的冲击试验,并根据波形要求进行调波。结果表明,仿真计算对现场试验具有重要的指导作用,在现场按照仿真计算得到的冲击电压发生器参数进行设定所得到的试验波形与仿真波形一致。在50%、75%、100%电压作用下设备未发现放电、击穿等现象,设备绝缘性能良好。
In the field,the oscillatory surge voltage is usually used to evaluate the insulation performance of GIS equipment. Based on a 750 kV substation,the voltage waveform of a 800 kV UHV GIS equipment under oscillatorylightning shock wave and the parameters of surge voltage generator were calculated by the numerical simulation soft-ware ATP-EMTP. According to on the simulation results,on-site impulse withstand voltage test was carried out on acertain interval of the 800 kV GIS equipment to evaluate the insulation performance of the equipment. Impulse testsunder 50%,75%,and 100% of the rated voltage of positive and negative polarities(corresponding to ±840,±1 260 and ±1 680 kV)were conducted,respectively,and the waveforms were adjusted according to the requirements. Theresults show that the simulating calculation plays an important guiding role in the field test. The waveforms of the on-site withstand test with the calculated parameters of surge voltage generator are in accordance with the simulationwaveforms. Under the action of 50%,75% or 100% rated voltage,no discharge or breakdown happened in the equipment,and the insulation performance of the equipment is good.
