摘要
综合电力系统可以为舰载高能功率武器等脉冲功率负荷提供瞬时高能。脉冲负荷具有极高瞬时功率,它的使用必将对系统电能质量带来较大的影响。为此就脉冲负荷对舰船综合电力系统的冲击作用进行了研究,其脉冲功率系统为储能电容充电电路形式。充电电路有2种不同拓扑结构:基于可控整流器和基于不可控整流-直流变换器。结果表明:脉冲负荷采用不可控整流器-直流变换器拓扑形式比采用可控整流器拓扑形式对系统造成的冲击小得多,并且电力推进的协同使用可进一步降低冲击强度。
Integrated Power System （IPS） can pride instantaneous high-energy for pulsed power loads, which have considerable effect on power quality. The impact of pulsed power loads on IPS is examined in this paper. The pulsed power load takes the form of a capacitor charging circuit. Two configurations are considered： a controlled rectifier based charger and an uncontrolled rectifier - dc/dc converter based charger. The results show that the system utilizing an uncontrolled rectifier in conjunction with a dc/dc converter has significantly less system impact than the system which utilizes a line commutated converter. It is also shown that the propulsion coordination can be used to further reduce the impact of pulsed power load on IPS.
