| 摘 要： | 综合电力系统是电力电子化的船舶电力系统,其低压交流配电网采用多逆变器并联运行方式作为电源,为低压日常负载供电。系统在某些特殊运行工况下,基于逆变器并联供电系统可能会产生并联谐振问题。本文分析了逆变器本体谐振、逆变器并联谐振产生的局部谐振和并联逆变器与负载网络之间产生的全局性谐振,建立相关的谐振网络模型,提出了谐振点的近似计算方法,可为中压直流综合电力系统的相关设计人员提供参考。

The inverter parallel resonance analysis of the medium voltage DC integrated power system |
| |
| Abstract: | The medium voltage DC integrated power system was a electric power system for the ship. The Low-voltage AC distribution network used multi-inverter parallel mode as its power supply. The resonance issues of parallel inverter under the ship operating conditions have been studied. By establishing the resonant network model of the inverter, the resonance of inverter itself, and parallel, and its network resonance conditions with the low-voltage AC distribution network have been analyzed.An approximate calculation method for the resonance point has been proposed ,which could be used as a reference for the relevant designers for the medium voltage DC integrated power system. |
