基于APF的城市轨道交通再生能源利用及谐波治理研究

Research about Harmonics Control and Harnessing of EMU Regenerative Energy Based on APF

针对轨道交通的制动再生电能,详述了制动能量的各种处理方法及其优缺点,指出了制动能量再生电能的意义;同时针对轨道交通供电的特点,指出了谐波对轨道交通供电系统和相连的电网系统的危害,提出利用有源电力滤波加以处理的方案。基于以上认识,利用瞬时无功控制算法理论,结合有源电力滤波设备,对二者进行综合控制策略研究,以实现谐波、无功补偿和制动再生电能的利用双重目的,并指出了这一系统的优点。

In light of the braking energy in urban rail transit, the paper states all methods of processing the energy and characters of different methods, points out that it is valuable to make full use of braking energy. At the same time, in light of the characters of urban transmit power in Supply System, it points out that harmonics is harmful to the power system, gives that it can be solved by using APF device. Based on this two meanings, using the instantaneous reactive power theory and active power filter, research about a combined control strategy for APF and regenerative technology is proposed. This control strategy not only achieves the functions of APF, but also achieves the harness of regenerative energy, and points out the characters of the system based on the strategy.
