Frequency controlling technique applied to the coal mine electromechanical equipments results in the absence of reactive power and harmonics pollution, which brings hidden troubles to power net in coal mine. Considering electromechanical equipment's safe and economic operation, this study opened with the mathematical model and parameters design of cascade STATCOM based on LCL filter. Then a low-pass filter time delay link and a PI controller were adopted for ensuring high dynamic response and low-frequency stable accuracy of the inner current loop. Eventually the repetitive control loop based on internal principal was used as outer current loop to realize zero static error tracking of referenced harmonic current, so that both high dynamic response and small steady-state error were obtained. Simulation and the actual device experiments validate the feasibility of the design.
