Reactive power compensation methods commonly used in power equipment
The centralized compensation is to set up the reactive power compensation device in the power distribution room to compensate the reactive power in the region. Due to the introduction of several kinds of compensation sampling is set at the point of measurement, so you can minimize the interest rate generated electricity.In the professional field and transmission line compensation (high and low), furnace low-pressure grid compensation, flameproof compensation device etc..
For the operation of specific projects, the compensation can be divided into: in situ dispersion compensation and centralized compensation.In situ compensation is to set up a reactive power compensation device on the spot to compensate for a single device. However, the need for compensation equipment, large investment, maintenance management is not easy.
Hello!Electrical equipment commonly used in reactive power compensation and the method of improving power factor are: synchronous motor, synchro, series capacitor compensation, shunt capacitor and series reactor compensation (EHV transmission line) and SVC, SVG compensation. SVG is through the power electronic device IGBT and its control circuit, a active VaR of equal amplitude and opposite to the size of the system, the reactive power compensation device for reactive power compensation to offset the system in recent years is the development direction of reactive power compensation.
