The continuous reactive power compensation device (hereinafter referred to as the device) is a new type of reactive power compensation device developed with the latest technology. At present, the reactive power compensation device of the power grid at home and abroad mainly adopts the method of grading switching of parallel capacitors, which can not make the reactive power of the power grid fully compensated. The power grid is still often in the state of under compensation or over compensation, and the power factor cannot be close to 1. This device has a great impact on the power supply The reactive power of the network is automatically and continuously compensated, so that the power factor is always close to 1, which can not only maximize the capacity of power supply equipment, but also avoid over compensation or under compensation of the power grid, play the effect of energy saving and power saving, and reduce the line loss. The device is applicable to the power users who need reactive power compensation, such as industrial and mining, medical treatment, scientific research, enterprises, oil and coal fields, ports, residential areas, public facilities, power grids, etc.
Basic principle: f f f f The basic principle diagram of continuous reactive power compensation (1) is the principle diagram of the device. The fixed capacitor and variable voltage source (UV) are connected to the power grid in series. By changing the size of the voltage source (UV), the compensation current of the capacitor is changed continuously to achieve continuous compensation. The selected variable voltage source (UV) must be a sine wave voltage with the same phase and frequency as the power grid voltage, and its voltage change range is 0-u.
