摘要/Abstract

摘要：

常规变频电源能实现独立供电功能,但无法达到无缝并网供电的要求。在变频电源为船舶提供供电前,必须先停止船舶主发电机组的供电。反之,也必须先停止变频电源系统的供电,然后才能恢复船舶发电机组的供电。本文重点讨论岸电系统的多机并联技术,采用微电网应用技术设计变频岸电电源系统,模拟船舶发电机的工作原理,通过电源检测传感器实时检测船舶电网的电压和频率,实时调整系统输出电源的电压和频率,以达到两者的同步,从而实现变频岸电电源系统的无缝并网供电功能。

Abstract:

Conventional frequency conversion power supply can achieve independent power supply function, but cannot meet the requirements of seamless power supply. Before the frequency conversion power supply for the ship to provide power, the ship’s main power generation unit must be stoped firstly. On the contrary, it is necessary to stop the power supply system of variable frequency power supply, and then to restore the power supply of the ship generator. In this paper the multi-level parallel shore power technology system is focused on, and by using the micro-grid application design of variable-frequency shore power system, simulating the working principle of ship generator, the voltage and frequency of power grid real-time detection of ship detection sensor, real-time adjustment of system output voltage and frequency of power source, to achieve the synchronization, so as to realize the seamless grid power supply functions of frequency and shore power supply system.

Key words: Ship shore power, multi-level parallel connection, grid connection, seamless switching
