The invention discloses a ship electric propulsion system, a ship and a control method, and relates to the technical field of ship electric power coordination control. The ship electric propulsion system comprises a propulsion motor, a propeller, a generator cut-off switch, a main transmission shaft and a load distribution board, the propulsion motor is connected with the propeller through the main transmission shaft, the propulsion motor is in driving connection with a steam turbine generator unit, and the steam turbine generator unit is electrically connected with a steam turbine control system. The steam turbine generator set module is connected with the switchboard through a generator circuit breaker switch, a power source of the propulsion motor is realized based on the switchboard, and a steam turbine generator set is connected into a ship power grid. According to the method, severe disturbance to the steam generator set during switching of complex working conditions of an electric propulsion ship is avoided, a large delay system of a primary loop can operate stably, safety of a power source is guaranteed, rotating speed fluctuation of the steam generator set in isolated network operation is within an allowable range, and safe operation of ship alternating current electric appliances is guaranteed.

    本发明公开了一种船舶电力推进系统、船舶和控制方法,本发明涉及船舶电力协调控制技术领域。该船舶电力推进系统,推进系统包括推进电机、螺旋桨、发电机断路开关、主传动轴、负荷配电板,其中推进电机通过主传动轴连接螺旋桨,且推进电机驱动连接有汽轮发电机组,汽轮发电机组电性连接有汽轮机控制系统,且汽轮机发电机组模块通过发电机断路器开关连接配电盘,推进电机动力来源基于配电盘实现,汽轮发电机组并入船舶电网内。本发明解决了电力推进船舶复杂工况切换时对汽发机组造成的剧烈扰动,可以使一回路的大延迟系统平稳运行,保证动力源的安全,使孤网运行下的汽发机组转速波动在允许范围内,保证船舶交流电器的安全运行。
