Design and Implementation of Three Level Coordinated Control System of Reactive Power and Voltage in Distribution Networks.

With the development of society, people's demand for electricity is increasing, and the requirement of power supply quality is higher and higher. The quality of electric power mainly depends on the regulation technology of electric power, however, the traditional reactive power and voltage control methods cannot meet the requirements of people's life. The paper introduces the existing problems of reactive power and voltage control, then introduces the three level coordinated control principle of reactive power and voltage in distribution network. At last, the three-level coordinated control system of reactive power and voltage in distribution network is designed. The system has a great effect on reactive power and voltage regulation of distribution network.
