电力推进系统功率限制控制策略在实船项目中的应用

Application of Power Limitation Control Strategy in Electric Propulsion System On Real Ship

采用电力推进的船舶中,推进系统是作为主要负载直接连接在船舶电网上,推进负荷的突变和电网结构的突变可能引起柴发机组过载、电网震荡甚至全船失电,此时船舶会面临失控的危险,甚至会倾覆,因此推进控制系统必须要与船舶电站进行协调控制,确保船舶电站的稳定和安全。本文针对以上存在的问题通过案例来引入功率限制的控制策略,并分析其实现过程和可行性,最后通过一些试验证明此方案确实可行。

The electric propulsion system is directly connected with the ship power station as the main load. Discontinuous propulsion load and the abnormal power station can lead to generator set overload, grid turbulence and even the whole ship power-loss. Now the ship will face the risk of out of control, even capsized, so the propulsion control system must be coordinated control with ship power station, ensure security and stability of ship power station. In this paper, power limit control strategy is introduced to solve the above mentioned problem, and its implementation procedure and feasibility are analyzed. Finally, this scheme is proved to be feasible by some experiments.
