This project uses parallel capacitors for reactive power compensation. There are three common methods of high-voltage centralized compensation, separate on-site compensation and low-voltage centralized compensation. This design uses low-voltage centralized compensation. Low-voltage centralized compensation refers to the installation of low-voltage capacitors on a 0.4V low-voltage bus of a 10kV substation. Compared with other methods, low-voltage centralized compensation has the advantages of simple wiring, convenient operation and maintenance, high utilization of capacitors, and high economic efficiency. It is one of the commonly used methods in reactive power compensation. The parallel capacitor control method adopts automatic adjustment method, commonly known as reactive power automatic compensation device. The schematic diagram of the principle circuit of the low-voltage reactive power automatic compensation device is shown in Figure 1.

This project uses parallel capacitors for reactive compensation. Common lying are three methods: high-pressure centralized compensation, in-place compensation alone and low-pressure centralized compensation. This design uses low-pressure centralized compensation. Low-voltage centralized compensation refers to the installation of low-voltage capacitors on a low-voltage bus at 0.4V of a 10kV substation. Compared with other methods, low-voltage centralized compensation has the advantages of simple wiring, convenient operation and maintenance, high utilization rate of capacitors, high economy and so on, and is one of the most commonly used means of reactive compensation at present. Parallel capacitor control method using automatic adjustment, commonly known as reactive automatic compensation device. The schematic of the principle circuit of the low-voltage reactive automatic compensation device is shown in Figure 1.

In this project, shunt capacitors are used for reactive power compensation. There are three common methods: high voltage centralized compensation, separate local compensation and low voltage centralized compensation. The design adopts low-voltage centralized compensation. Low voltage centralized compensation refers to the installation of low-voltage capacitors on the 0.4V low-voltage bus of 10kV substation. Compared with other methods, low-voltage centralized compensation has the advantages of simple wiring, convenient operation and maintenance, high utilization rate of capacitor, high economy and so on. It is one of the commonly used means of reactive power compensation at present. The control mode of shunt capacitor adopts the automatic regulation mode, which is commonly known as the automatic reactive power compensation device.
