Reactive Power Compensation of 10kV A-Line by MCR Reactive Power Compensation Device under MFAC Control Strategy

This paper delves into the compensation principle and mathematical modeling of the Magnetic-Valve Controllable Reactor (MCR) reactive power compensation device. It further investigates the device's response attributes under two distinct control strategies: Proportional Integral (PI) control and Model Free Adaptive Control (MFAC). A comparative analysis is drawn between these two control strategies, examining their stability, stability margin, and steady-state output error. The performance of the MCR reactive power compensation device deployed on a 10kV AC bus under both control strategies is discussed. The paper underscores the viability of the MFAC control strategy for the MCR reactive power compensation device. Furthermore, the device's ability to counter sudden reactive power shortages, as per the 10kV A-Line analysis model, is explored.
