Abstract
This paper describes the internal reactive power compensation system development, the problems facing the development. From product quality, performance and application to see the difference between reactive power compensation device; the industry made reactive power compensation device to see the problems as well as its development trend. At the same time also a detailed introduction to Le in this design the most important component parts of SCM concept, working principle and equipment of the overall structure, MCS-51 development of, selection basis. Designed based on MCS-51 microcontroller reactive power compensation control system introduced by the use of 8031,8255 and other microcontroller. The device can achieve the power factor compensation from COS ∮ = 0.6 to COS ∮ = 0.95, and can ensure that the power factor changes, the switching capacitance, real-time indications of the current, power factor, current and active power, and can perform manual and automated control
Key words: reactive power compensation, SCM, SSR
