Compensation Methods for Power Capacitors |
Posted: November 9, 2021 |
There are three compensation methods for power capacitors: individual compensation, group compensation and centralized compensation, all of which are suitable for current load occasions. 1) Individual compensation is to install the power capacitor near the electrical equipment that needs compensation, and run and exit at the same time with the electrical equipment during use. The individual compensation is at the end load of the power supply. It can compensate for all high and low voltage transmission lines in front of the installation site. And the non-power of the transformer can minimize the reactive power transmission of the system and reduce the active power loss of the entire line and the transformer. 2) Group compensation, that is, for groups of electrical equipment, each group uses capacitors for compensation. The utilization rate is larger than that of individual compensation, so the total capacity of the capacitor is also smaller than that of individual compensation, and the investment is smaller than that of individual compensation. However, it cannot compensate the reactive power on the distribution line from the compensation point to the electrical equipment. 3) The power capacitors for centralized compensation are usually installed on the high and low voltage busbars of substations and distribution stations. Centrally compensated power capacitors are placed on the high-voltage bus of the user's total reduction substation. This method has low investment and is convenient for centralized management; at the same time, it can compensate the user's reactive power on the high-voltage side to meet the power factor requirements of the power supply department. But it has no reactive power compensation for the internal circuit behind the bus. There are more detailed information you can found on Easybom. You can have a deep insight into them.
