摘要
新概念武器和全电力推进技术的上舰使用,使舰船的战斗力和生命力发生了革命性的飞跃。研究了现代舰船电力系统的构成、运行特点及面临的谐波污染问题,分析了谐波产生的原因及对舰船电网造成的危害。针对性地提出用并联型有源电力滤波器抑制舰船电力谐波,并对其补偿机理和特性做了说明。与传统方法相比,该法响应速度快,稳定性好,在舰船上具有较好的实用价值和应用前景。
The use of new conception weapons and ships electric power propulsion technique improved the battle effectiveness and life-force of the ships, and also aggravated the harmonics pollution of the ships electric power system. The harmonics pollution reduced the economical operation and reliability of the ships. This paper discussed the structure and running characteristics of the ships electric power system, analyzed the causes of the harmonic＇s origination from generate electricity system, transmit electricity system and use electricity system, and described the harmonic＇s harm to the ships electric power system. Considering the characteristics of the ship harmonics suppression, the paper presented using the shunt active power filter （APF） to suppress the harmonics, and explained the principle and characteristics of the APF. Compared with the traditional harmonics suppression method, this proposed method has the virtue of quick response and better stability, and has better practical value and applied foreground.
