Needs to restructuring of protection systems for power electronic converters
Mohammad Mahdi Mansouri
Protection systems have widespread problems with expansion of power electronic equipment in size and diversity. Therefore, a short review is done on these problems and some basic requirements of a protection system are mentioned base on relay protection foundation. Then a protection block is proposed for protection of power electronic equipment. The proposed protection scheme has independent measuring unit, calculation unit and circuit breaker. It is shown that these three parts are unqualified in current protection system for protection of power electronic equipment. One of the main results of this paper proposal is using the solid state breakers instead of mechanical breakers. In this regard, a comparison of cost and space between mechanical and solid state breakers is done. Some special protection schemes are mentioned for power electronics at the end.
