Reactive Power Compensation Controller - Control Mode

There are three sampling methods for reactive power compensation controllers: power factor type, reactive power type, and reactive current type. Choosing which physical control method is actually the choice of reactive power compensation controller. The controller is the command system of the reactive power compensation device, which completes functions such as sampling, calculation, sending switching signals, parameter setting, measurement, and component protection. Over the past decade, it has undergone a rapid development process from discrete components to integrated circuits, microcontrollers, and DSP chips, and its functions have become increasingly sophisticated. As for the overall situation in China, due to the high demand in the market and the increasing number of manufacturers, there are significant differences in their performance and internal quality. Many products do not live up to their names and need to be taken seriously when selecting. Another issue to note when selecting is that domestically produced controllers are all named "XXX Reactive Power Compensation Controller", and the meaning of "reactive power" in the name is not the sampling physical quantity of this controller. The sampling physical quantity depends on the product model, not the product name.
