Calculating the Capacity of Concentrate Compensatory Capacitor on Different Compensatory Purpose

Setting up the compensatory capacitor in the transformer station is the main manner of reactive power compensation currently.It can increase the bus voltage,decrease the loss of electricity,improve the power transmission and reduce the energy change cost,through adding reactive power compensation.Although these functions are correlative,the purpose of compensation is different,and the calculation of compensative capacity is different too.This text deduces different capacities of compensation purpose which setting up compensatory capacitor requires from the point of view of the fixed quantify through the theoretical analysis.
