Fixed Frequency Hysteresis Control Based STATCOM
The operation principle of STATCOM (Synchronous Static Compensator - STATCOM) is analyzed. To improve STATCOM response speed, and to sustain the STATCOM main circuit switching device operating frequency stability, the direct current control method is introduced. Fixed frequency hysteresis control method based on the traditional hysteresis control strategy is proposed. The proposed strategy is simple, high precision, fast response speed, while it has less fluctuation with the impact of load parameters, and good robust characteristics.
