摘要: 新建特高压线路进行工频参数测量时,邻近的平行线路在测试线路上产生的感应电压、电流则有可能对参数测试的准确性产生较大的影响,还可能对试验人员、设备的安全造成一定威胁,因此有必要对平行线路在特高压线路上的感应电压、感应电流的计算方法及各种线路参数对计算结果的影响进行研究。以锡盟—山东特高压线路中的锡盟—北京东段实际线路为模型,通过EMTP-ATP软件计算平行500 kV线路在特高压线路上所产生的感应电压、感应电流,并针对各种参数对感应电压、感应电流计算的影响进行了分析。计算结果表明,平行段线路长度、平行段线路间距、换位方式、输送功率、线路高抗、串补电容均会对感应电压、感应电流产生影响。

Abstract: The induced voltage and current produced by parallel lines may influence the result of AC parameter test and threaten operator and instrument safety. It is necessary to research computational method of induced voltage and current of UHV circuits produced by parallel lines and the influence of various circuit parameters on calculation result. Taken Ximeng-Beijingdong UHV line as example, induced voltage and current of UHV circuits produced by parallel 500 kV lines are calculated and analyzed by EMTP-ATP simulation software. Calculation results show that parallel length, parallel distance, transposition method, transmission power, high voltage shunt reactor, series compensation capacitor all have influence on induced voltage and current.

Key words: UHV circuit, parallel lines, induced voltage, induced current
