摘要
针对工业负荷运行时产生大量负序和谐波电流的情况,提出了一种可以补偿负序和谐波电流的静止无功发生器控制策略,该策略对正、负序电流分别采用dq轴电流解耦跟踪控制,对谐波电流采用比例谐振(PR)电流控制。最后通过实时数字仿真(RTDS)和动模试验验证了在实际工程中SVG控制器负序和谐波补偿算法的正确性。
Aiming at large amount of negative sequence and harmonic current generated in industrial load operation, this paper raised a static var generator control strategy which may compensate negative and harmonic current. The strategy adopted dq-axis current decoupling tracking control for positive and negative current respectively and used proportion resonance (PR) current control for harmonic current. At last, real-time digital simulation (RTDS) and dynamic model test verified correctness of negative sequence and harmonic compensation algorithm of practical engineering static var generator (SVG) controller.
