Popis: Based on the background of Huainan–Wannan UHV AC double circuit transmission line, the mechanism of the transient recovery voltage (TRV) is analyzed in the case of a wire of split conductor failure. The simulation model is established to simulate the TRV of the circuit breaker when the multiple split conductors are in different positions, and the influence of the induced voltage on the TRV is also considered. The simulation results show that the more the number of fault split conductors is, the more serious the TRV is, and the peak and rate of rise of TRV are increased due to the induced voltage. Therefore, it is very important to consider the coupling effect on the transient characteristics of circuit breakers in practical engineering.
