Abstract

This paper presents an analysis of the power regulation of a SMES unit under PWM switching control. The criteria for executing a power limit scheme to maintain power flows of the SMES unit within a controllable range are described. A general technique for design of power controllers based on the power limit scheme is developed. Two illustrative examples, being separate active and reactive power compensations of a model power system, are presented. The study indicates that active power priority control plays a dominant role in the power regulation of a SMES unit. Experimental results for two examples are also presented
