Abstract

The loss of line is increased and end terminal low voltage due to three-phase unbalance of low voltage distribution network. Therefore

control of unbalance of three-phase has very important and practical significance. In this paper

the study of load unbalance control technology at area of low voltage distribution network is developed. Firstly

the operating principle and key technology of intelligent phase selection switch is introduced. Then

the study of load unbalance control strategy at area of low voltage network based on intelligent phase election switch is performed. Finally

the actual 380 V sample is developed. It is proved by the test that this technology can solve the problem to control three-phase load unbalance at area of low voltage network

and has such advantage as low cost and high reliability and is suitable for the promotion and application.
