Design of dynamic reactive power compensation scheme for 220kV ring network
ABSTRACT
Dynamic reactive power compensation system is widely used, such as electronic equipment, power generation system, transmission line, etc., will be used in dynamic reactive power compensation system or tools. The dynamic reactive power compensation system with higher efficiency and stability is always the focus of research. In power system, dynamic reactive power compensation system can be seen everywhere, because of the advantages of stable operation and high control accuracy, and dynamic reactive power compensation system has a very good advantage in power system compensation. With the continuous innovation of automatic control technology and microelectronics technology, the present technical level has laid a solid foundation and theoretical basis for the realization of dynamic reactive power compensation control. Dynamic reactive power compensation design has many resources, rich development experience and low cost advantages, and has gradually become the focus of the world. With the continuous innovation in the field of reactive power compensation system, the number is increasing and gradually become the focus of research, so we should seriously study the composition of reactive power compensation system.
Dynamic reactive power compensation device is one of the important measures to improve power factor and reduce power line loss. This paper introduces the dynamic reactive power compensation technology in the 220 kv power grid, the application of determining the location of the dynamic reactive power compensation, the choice of dynamic reactive power compensation device scheme, and by using the simulation software Matlab reactive compensation current and power factor of power grid after modeling, finished the simulation test and experimental research, set up the simulation platform, Matlab simulation tool is used to simulate the reactive power compensation effect of the control system.
Key words ： 220 kv power grid; Dynamic reactive power compensation; Matlab; Modeling and simulation
