    capacitor dimensionTips: Three compensation ways for power capacitor

    There are three ways of compensation for power capacitors: Individual compensation, packet compensation and centralized compensation.

    1. Individual compensation is to set the power capacitor near electrical equipment where requires compensation, and runs and exits together with electrical equipment, which is at the end of the power supply load. It can compensate all high and low voltage transmission lines and transformers which have no power, can minimize reducing reactive power throughput of the system, and makes the whole line and transformer active loss reduction, and the cross section of the wire, the capacity of transformer switchgear equipment such as reduced size, it has the best compensation effect.

    2. For packet compensation, the capacitor is used to compensate each group. The utilization ratio is larger than the individual compensation, so the total capacity of capacitor is smaller than the individual compensation, and the investment is smaller than the individual compensation. However, the reactive power of the distribution line from compensation point to power equipment cannot be compensated.

    3. For power capacitors with concentrated compensation, they are usually set on high and low voltage busbars of transformer and distribution substation. The power capacitors that will be centrally compensated are set on the high voltage bus of the user's total drop substation, which has less investment and is convenient for centralized management. At the same time, it can compensate the reactive power of user to meet the requirements from power factor. However, there is no reactive power compensation for the internal line of bus.
