| 摘 要： | 针对高压交流配电系统,提出一种基于线性并联变压器谐波阻抗控制的并联型有源电力滤波器新原理.实时检测并联变压器一次侧的谐波电流,通过逆变器向二次侧注入谐波补偿电流,在一定的补偿系数下,并联变压器一次侧对谐波电流呈现近似为零的低阻抗,而对基波电流呈现很大的一次侧自阻抗,从而输导配电系统中的谐波电流流入并联变压器支路.这种滤波原理在10～35 kV高压交流配电系统中将有着广阔的应用前景.仿真和实验结果证明了这种滤波新原理的正确性.

| Abstract: | On the basis of active power filter linear shunt transformer harmonic impedance control, a novel principle for high voltage alternate power distribution systems is proposed. The harmonic current of the primary winding was detected and multiplied by a compensation coefficient to get a reference current, which was tracked by a voltage source inverter to produce a harmonic compensation current. In a certain compensation coefficient, the primary of the shunt transformer can really exhibit nearly zero impedance to harmonic current and very high primary self-impedance to fundamental current and thus lead harmonic current to flow into the shunt transformer circuit. This principle can be used in 10-35 kV alternate power distribution systems widely. The new principle has been verified by the simulation and experiments. |
