【摘要】 金属氧化物避雷器(MOA)可作为输电线路、串联电容补偿等电力设备的过电压保护的重要设备。利用MATLAB软件中的电力系统模块库(PSB),建立了含有串联电容补偿的超高压输电线路系统模型,模型对MOA过电压保护性能进行了仿真,结果表明,过电压保护补偿装置能快速有效地切除故障动作,对MOA的设计和选用有一定的参考价值。更多还原

【Abstract】 Metal oxide arresters(MOA)can be an important device for overvoltage protection in transmission line and electric power equipment such as series capacitance compensation.A system model based on the Power System Block set(PSB)of MATLAB for EHV transmission line with series compensation is established,and the overvoltage protection capability of MOA is simulated.The result showed that failure action can be eliminated quickly and effectively by overvoltage protection compensation devices.It provides some reference for the study and selection of MOA.更多还原
