Simulation Model of Shipboard Low Voltage Molded Case Circuit Breaker Based on PSCAD/EMTDC


A simulation model of shipboard low voltage molded case circuit breaker (MCCB) is developed based on power system simulation software PSCAD/EMTDC. The motion characteristic of the magnetic instantaneous acting trip based on electromagnetic characteristic analysis and Cassie arc model are applied into the simulation model to describe the dynamic behavior of the MCCB
during short-circuit protection. The results of short-circuit interruption experiments verify the simulation model. It demonstrates that the simulation model has good prospect in optimizing the design and protection performance of MCCB.
