The reactive power compensation controller is the core component of the reactive power compensation device and plays an important role. Most manufacturers of reactive power compensation devices buy controllers and then assemble the whole machine themselves. There are not many manufacturers with the ability to design and manufacture controllers. , there are even fewer manufacturers that can design and manufacture controllers with excellent performance.
Existing low-end controllers are controlled based on power factor. Although this kind of controller is cheap, its performance is very poor and has been eliminated, so it will not be introduced here.
Existing high-end controllers are controlled based on reactive power, but in addition, the design often focuses on Chinese character display and data communication. In fact, it is quite complicated to truly realize perfect reactive power compensation control. Achieving perfect reactive power compensation control is the main function of the reactive power compensation controller. Only when the main functions are quite complete, additional functions can be considered.
