【摘要】 有源滤波型静止无功发生器是静止无功发生器基本功能与有源滤波器的谐波补偿功能相结合的先进电力电子装置.本文针对有源滤波型中压静止无功发生器(SVG)的技术特点要求,采用全数字的直接电流控制方法,从控制原理、指令电流检测算法、软硬件设计几个方面阐述了有源滤波型中压SVG控制系统的研制过程.通过MATLAB仿真研究验证了所提出的各种补偿功能下的控制方法,并证实了该控制系统的快速性和有效性,以及有源滤波型中压SVG的良好补偿性能。更多还原

【Abstract】 Static var generator with active filter function is an advanced power electronics device, which combine the fundamental function of static var generator(SVG) and the function of compensating harmonics of active power filter(APF). According to the technical requirements of medium-voltage SVG with active filter function, this paper introduces the development of its control system in several aspects. The simulation results through MATLAB confirm the control methods under different compensating functions, and rapid response and validity of the control system, and also good compensating performance of medium-voltage SVG with active filter function.更多还原
