Based on the device capacity and compensation requirements, it can be divided into a basic cabinet and an expansion cabinet. The expansion cabinet supplements the capacity of the basic cabinet. The basic cabinet can perform compensation independently, while the expansion cabinet must be used in conjunction with the basic cabinet.
Functions: Improve the power factor to above 0.9 to avoid reactive power penalties; stabilize the grid voltage to meet national standards or user requirements; reduce the power supply capacity of the transformer; reduce the losses of the power supply and distribution system, and save electricity.
Basic Principle: After the load is running, reactive current is exchanged between the load and the power grid. At this time, the single-chip microcomputer of the compensation device detects the size of the current inductive reactive current and immediately issues a command to input the corresponding capacitive current to offset the inductive reactive power, improve the power supply capacity of the power grid, and ensure the reliable operation of electrical equipment.
