Research on Intelligent Control Technology of Reactive Power Compensation
In the distribution network, reactive power is an important factor influencing voltage stability, and it is related to the safe and stable operation of whole power system. Reactive power compensation is to improve the reactive power, and it is one of the effective measures to ensure the high-efficiency and reliable operation of the power system. In order to improve the power supply capacity of equipment, improve the voltage quality, improve the power factor, reactive power compensation scheme is designed. The realization of reactive power compensation uses the parallel compensation capacitor and takes the ways of low-voltage centralized compensation. To the compensation control strategy, an improved Nine–zone diagram is used. Then choose a reasonable capacity of parallel capacitor according to the calculation of formula. Thus capacitor switching is controlled by software to complete real-time control of the transformer reactive power compensation.
