The static reactive power generation device is a new type of specialized equipment for reactive power compensation made using modern power electronics technology and digital signal processing technology based on high-speed DSP devices. It consists of two main parts: the instruction current operation circuit and the compensation current generation circuit. The instruction current calculation circuit monitors the current in the circuit in real time, converts the analog current signal into a digital signal, and sends it to a high-speed digital signal processor (DSP) for processing to analyze the reactive power content of the load current. It sends a driving pulse in the form of a pulse width modulation (PWM) signal to the compensation current generation circuit, drives the IGBT or IPM power module, generates the required reactive compensation current, and injects the reactive compensation current into the power grid, Thus achieving the purpose of dynamic reactive power compensation.
