Abstract
With the development of modernPower Electronics Technology, SVG is an important issue as well as a heated topic that involved in the power electronics technology, power systems Power System, Electric Automation, Theory electricians and other areas, as well as various fields in recent years one of the hot topics. Based on the deep study of SVG from home and abroad, the design presents a new type of SVG. That is, the Porver Parallel SVG, which is made up of four components: the main circuit, detection circuit, control circuit, and Driving Circuit Driving Circuit. Parallel main circuit includes fixed compensation capacitance, inductance, variable compensation and GTO devices. Through hardware, Detection circuit gets the reactive power size of real-time compensation and realizes the multiplication and addition operations. PWM control circuit pulse, so that the device tracking compensation. As compensation to the current and voltage phase proximity, Compensation is the Power Factor Power Factor close, Therefore, to achieve the static reactive power compensation Static Var Compensator purposes. Control Circuit control circuit using high-speed optocoupler. so that the main circuit and control circuit isolation, but also using the PWM control technology in tracking compensation reactive power grid. The harmonic little.
