In order to solve the problem in reactive power compensation of oilfield distribution systems at present, a Taboo search algorithm is proposed in this paper, by which the optimal location and size of shunt capacitors on distribution systems are determined. Then the voltage profile is improved and the active power loss is reduced. In this paper, Voltage qualified is used as objective function to search an initial solution that meets the voltage constraints so that it is feasible in practicable voltage range; then the global optimum solution can be got when taking the reduced maximum of active power loss as objective unction. The examples show that the improved algorithm is feasible and effective.

In this paper, the impuissance of traditional ip-iq method in reactive power compensation applications under nonideal mains voltages is illustrated first, and then a novel current reference calculation method for Shunt Active Power Filter (SAPF) based on p-q transformation is proposed. By means of the proposed method, the positive sequence fundamental active current component of the load current can be isolated under distorted and/or unbalanced mains voltages, which makes SAPF be capable of harmonic cancellation and reactive power compensation at the same time under nonideal mains voltages. The effectiveness of the new proposed method is mathematically studied and verified by computer simulation under ideal and nonideal mains voltages.
