摘　　要：短路开断试验是容量试验站考核断路器开断短路故障的能力,是断路器型式试验的核心项目之一。断路器开断瞬间要求断口间承受标准规定的预期TRV参数及波形。依据国家标准GB 1984-2014《高压交流断路器》对短路开断试验中两参数TRV的规定,研究了用于中压断路器短路开断试验的两参数TRV计算方法,开发的计算程序可以自动实现TRV波形计算及标准值参数读取。最后,通过与PSCAD/EMTDC搭建的仿真模型计算结果进行比对分析,结果表明开发的两参数TRV计算程序的结果与仿真结果一致,可以满足容量试验站对TRV参数计算的需求。Short circuit breaking tests are one of the core items of circuit-breakers type test,which is used to assess the ability to break short circuit fault in high power test station.The breaking moment of the circuit-breakers require the expected TRV parameters and waveforms between the interrupters specified in the standard.According to the provisions of the national standard GB 1984-2014 on two parameter TRV in short circuit breaking test,the two parameter TRV calculation method for the short-circuit breaking test of medium voltage circuit-breakers is studied.The developed calculation program can automatically calculate the TRV waveform and read the standard value parameters.Finally,through the comparison and analysis with the calculation results of the simulation model built by PSCAD/EMTDC,the results show that the two TRV calculation program developed are consistent with the simulation results,which can meet the requirements of TRV parameter calculation in high power test station.
