摘要
电力推进船舶电网不同于陆上电网,由于发电容量有限,供电系统相对独立,对非线性负荷的抗干扰能力差。针对传统滤波方法存在的问题,文中提出一种利用新型推进变压器结构实施谐波抑制的新型感应滤波技术,并对推进变压器绕组结构设计、滤波原理进行介绍。对基于新型推进变压器的6相交–直–交推进方式船舶电力系统进行了Simulink仿真,仿真结果验证了文中所提出方案的正确性和可行性。
Different from terrestrial power grids, due to its finite generation capacity the electric propulsion ship power system is a relatively independent system and its antiinterference ability to nonlinear load is weak. For the existing problem in traditional filtering methods, a new sensor filtering technique, which uses new type of propulsion transformer to implement harmonic suppression, is proposed, and the structural design of the winding of this propulsion transformer and the filtering principle are presented. The 6-phase AC-DC-AC propulsive ship power system based on the new type of propulsion transformer is simulated by Simulink, and the correctness and feasibility of the proposed scheme are verified by simulation results.
