Research on the net present value comparison of shunt power quality compensators under complex conditions
摘要
Abstract
Power quality problems such as harmonics, reactive power and unbalance in distribution network are becoming more and more prominent, so the operating conditions of the power quality compensators become complicated. In order to analyze the economy of active, passive and hybrid compensators under complex conditions, the net present value comparison research of the three shunt compensators is carried out. Firstly, the field investigation is carried out on the operating conditions of the power quality compensators in distribution network, and the compensation effects of the three types of compensators under complex conditions are simulated by the measured data. Secondly, according to the simulation results, the economic evaluation of the compensators is carried out by net present value method. The net present value expressions of the three compensators are derived, and the net present value changed areas with the change of harmonic, unbalanced current and reactive power under complex conditions are obtained. Finally, an example is given to verify the analysis results.关键词
