摘要
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 a kind of special micro-grid such as offshore platform power system for research background, the main features and characteristic harmonics of offshore platform power system are emphatically analyzed. Under the presupposition that the demand of reactive power compensation is met, an approach to eliminate harmonics of offshore platform power system by use ofthyristor switched filter is given; based on the place measured harmonic data and by use of genetic algorithm the optimal design of parameters of thyristor switched filter is performed. Simulation results by Matlab show that thyristor switched filter can well eliminate harmonics of offshore platform power system while the demand of reactive power compensation is considered.
