| 摘 要： | 将岸电电源模拟为虚拟同步发电机的特性,可提升船舶电网对岸电电源的接纳能力,然而岸电电源在并入船舶电网时,通常存在较大的瞬间冲击电流。本文提出了一种预同步并网方法。首先介绍了虚拟同步发电机的原理,并分析其并网过程存在的问题,在此基础上提出了预同步的并网方法并介绍锁相环的设计。最后进行仿真研究,结果验证了所提方法的有效性。

| Abstract: | Simulating the shore power as a virtual synchronous generator can improve the parallel connection capacity of shore and ship power grid.However,when the shore power is integrated into the ship power grid,there is usually a large instantaneous current.In this paper,the principle of virtual synchronous generator is introduced firstly,and the existing problems in the grid-connection process are analyzed.On this basis,a method of pre-synchronous and the design of PLL are presented.Finally,the Matlab/Simulink simulation results verify the effectiveness of the proposed method. |
