Study on Automatic Gird-connection Control Strategy of Marine Synchronous Generator
Automatic quasi-synchronization is one of the main functions of ship power station automation. Based on the analysis of ripple voltage grid-connection principle of synchronous generator and the grid,this paper proposes an automatic quasi-synchronization control strategy of the generator. Grid-connection principle of ripple voltage has been improved and a practical gird-connection time calculation method suitable for the discrete calculations has been proposed. Simulation and experimental results fully validate the effectiveness of the grid-connection control strategy and algorithm.
