description

In this paper, voltage dips simulation in electric power MV distribution networks by using an improved ATP circuit-breaker model are reported. An equivalent circuit of a MV distribution system is employed. The circuit-breaker is simulated by using a tool written in MODELS language and by arranging a time-variable differential arc-conductance based on the combination of Mayr's and Cassie's equations. The simulations carried out have shown how the amplitude of the voltage dips depends on the type and location of the fault and their duration is strictly related to the circuit-breaker parameters.
