SVG reactive power compensation consists of three basic functional modules: detection module, control operation module and compensation output module. The working principle of SVG reactive power compensation is the current information of the external CT detection system, and then the current information, such as PF, s, Q, etc. is analyzed through the control chip; then the controller gives the drive signal of compensation, and finally the inverter circuit composed of the power electronics inverter circuit sends the compensation current.Principle:Svg reactive power compensation adopts IGBT to form a self commutating bridge circuit, which is connected to the power grid through a reactor in parallel. The amplitude and phase of the output voltage at the AC side of the bridge circuit can be properly adjusted, or the current at the AC side can be directly controlled. Quickly absorb or send out the required reactive power to realize the purpose of fast dynamic regulation of reactive power. As an active compensation device, SVG can not only track the impulse current of impulse load, but also track the harmonic current.The voltage source inverter consists of two parts: DC capacitor and inverter bridge, in which the inverter bridge consists of a semiconductor device IGBT which can be turned off.In SVG reactive power compensation, the amplitude and phase of DC inverter to AC voltage can be controlled by adjusting the switch of IGBT device in the inverter bridge. Therefore, the whole device is equivalent to a phase modulation power supply. By detecting the reactive power needed in the system, the reactive power of the same size and opposite phase can be sent out quickly, the local balance of reactive power can be realized, and the operation of the system with practical high rate factor can be maintained.The SVG reactive power compensation of Nande Electric has the continuous, smooth and linear reactive power compensation ability, which can replace the traditional split phase capacitor. The arbitrary target power factor value can be set, the dynamic response speed is fast, the compensation accuracy is high, the inductive reactive power and capacitive reactive power can be compensated. The SVG reactive power compensation has the significant advantages of high power density, high efficiency, low cost and low noise. The parallel and plug-in modular design, with exquisite structure and flexible design, can be used as the standard device of power distribution system; support the third-party cabinet embedding.
