Considering that the traditional STATCOM could not compensate for the unbalance nonlinearity load system; a new STATCOM control method is proposed. Compared with traditional one, the STATCOM can com?pensate for reactive current and unbalance current characteristics and APF can compensate for harmonic current characteristics. Firstly, the overall structure of the new STATCOM control method is given, and then the struc?ture and principles of three modules are introduced. Finally, a simulation module is built in PSIM software. The simulation results verify the correctness of the proposed method.
