摘要

暂态恢复电压（TRV）标准值参数是考核高压交流断路器在大容量试验站进行短路开断试验时的一项重要指标。文中提出了一种基于坐标系转换的TRV波形包络线与标准值参数计算方法

通过对TRV波形数据经过数学运算由笛卡尔坐标系转换到极坐标系下

进一步对极坐标系下的TRV波形数据计算可以得出与TRV波形相切的3条直线（两参数TRV）或4条包直线（四参数TRV）所组成的包络线以及TRV的标准值参数。应用该计算方法所获得TRV标准值参数

为大容量试验站进行短路开断试验时

预期TRV调试时试验回路R、L、C元件参数的调整以及试验后TRV参数的读取与评定提供了理论依据。

Abstract

The transient recovery voltage（TRV）standard value parameters are an important indicator for the shortcircuit breaking test of high voltage circuit-breakers at the high power test station. This paper presents a calculationmethod of TRV waveform envelope and standard value parameters

which is converted the TRV waveform data fromthe Cartesian coordinate system to the polar coordinate system

and gain three straight lines of two-parameters TRVor four straight lines of four-parameters TRV tangent to the TRV waveform and the TRV standard parameter value bycalculated the TRV waveform data in the polar coordinate system. The TRV standard value parameters are obtainedby this calculation method

which can provide the theory basis for adjusting the R

L and C parameters of the test cir-cuit

and provide the theory basis for reading and evaluation the TRV parameters after the test when proceeding short-circuit breaking test at the high power station.
