In this paper

the application of magnetic controlled reactor（MCR） in the actual project of regional power grid of power company is particularly introduced

and its practicability and applicability during the application is concluded and summarized. Such contents as typical supply area environment

configuration mode

technical principle and control mode of actual operation for the application of MCR in the regional power grid is introduced by way of combing the actual application of MCR in Zhejiang Province and

on the basis of which

the applicability of MCR in the regional power grid is analyzed and discussed further from such aspects as voltage-reactive power compensation control result and operation & maintenance of equipment. Finally

the technical work to be developed in the future is prospected

which lays foundation for the promotion and application of FACTS（flexible AC transmission system equipment）in the regional power grid.
