Installing a high temperature superconducting fault current limiter (HSCFCL) in electrical power systems is an effective measure to limit the fault short circuit current and to reduce breaking capacity of the circuit breaker.

The fault current-limiting duration of HSCFCL is determined and its principle is sized up.

They are widely used to operate relays that turn on electric motors and other electrical apparatus. The main components of a contactor are contacts, the springs, the magnets and a coil, so the designer of contactors needs to predict their mechanical and electrical performance. This is a coupled problem of electromagnetic fields, transient circuits and mechanical movement.

By using a fuzzy inference method, the ISA can not only reject infeasible design schemes before design calculation, but can also circumscribe the whereabouts of the global optimum and automatically narrow the search scope. In case of making improper decisions in ISA searching, a criterion of recognizing error judgment is developed. The algorithm is applied to the optimal design of induction motors used in electric locomotives, and satisfactory results are achieved.","PeriodicalId":143007,"journal":{"name":"ICEMS'2001.
