以海洋平台电力系统这一类特殊的微电网为背景,重点分析海洋平台电力系统的主要特点和特征次谐波。在满足无功补偿要求的前提下,利用晶闸管投切滤波器对海洋平台电力系统的谐波进行治理,根据实地测量的电网谐波,利用遗传算法对晶闸管投切滤波器的参数进行优化设计。Matlab软件的仿真结果表明,晶闸管投切滤波器对海洋平台电力系统谐波的治理效果比较好,并且兼顾了无功补偿的要求。
Taking the special microgrid as a kind of offshore platform power system as the background, the main characteristics and characteristics of the offshore platform power system are analyzed. On the premise of meeting reactive power compensation requirements, thyristor switching filter is used to control the power system harmonics of the offshore platform. Based on the field harmonic measured in the field, genetic algorithm is used to optimize the parameters of thyristor switching filter. The simulation results of Matlab software show that thyristor switching filter has a good effect on the harmonic control of offshore power system, and takes into account the requirements of reactive power compensation.
