电力系统中电力电子装置的广泛应用,为电网中注入了一定的谐波及无功电流,从而影响电网的稳定运行.本文提出了一种基于超导储能系统并采用直接功率控制的有源电力滤波器.与传统的有源电力滤波器相比,超导储能系统不但可以滤除谐波,还可以滤除有功功率波动.通过Matlab/Simulink对基于超导储能系统的有源电力滤波器进行仿真验证.
The widely application of electronics and electric devices in the power system have an effect upon the stable operation of electric network, because of its injection harmonic and idle current in the system. In this paper, an Active Power Filter(APF) based on Superconducting Magnetic Energy Storage(SMES) system which adopt direct power control strategy has been shown. Compared with the traditional APF, SMES system can filter not only the harmonic but also the fluctuate of the active power. By use of Matlab/Simulink software, this thesis proved the feasibility of the system.
