Reactive Power Compensation Technology

Reactive power compensation is a technology that improves the power factor of the power grid in the power supply system, reduces losses in power transformers and transmission lines, enhances power supply efficiency, and improves the power supply environment. So reactive power compensation devices are in an indispensable and very important position in the power supply system. Reasonable selection of compensation devices can achieve the maximum reduction of power grid losses and improve the quality of the power grid. On the contrary, improper selection or use may cause various factors such as power supply system, voltage fluctuations, and increased harmonics. Detailed introduction of the basic principles, significance, switching methods, circuits, controllers, high and low voltage devices, compensation methods, and existing problems of reactive power compensation.
