Abstract

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
