基于大负载的中压供电船舶综合电力系统仿真研究

Simulation research on medium voltage power supply ship integrated power system based on large load

配置大功率负载是航母等现代大型舰船的需要。大功率负载设备受工况和海况的多重影响,频繁的工作极易产生大幅功率波动,对包括电压、电流、频率等电网安全稳定造成影响和冲击。基于综合电力系统构建“船舶电站-逆变器-推进电机-螺旋桨”的完整电能链,根据大功率负载的工作情况,对大功率负载投入时电网的电压、电流、转速和扭矩等关键指标进行理论分析、计算和仿真,获得完备数据以保障中压供电大负荷船舶综合电力系统的有效运行。

It is a necessary demand for modern large-scale ships such as aircraft carriers to configure high-power loads.High power load equipment is subject to multiple affects of working conditions and sea conditions,and continual work is prone to generate large power fluctuations,which will affect the safety and stability of power grid including voltage,current and frequency.Based on the integrated power system,a complete power chain of"ship power station-inverter propulsion motor-propeller"is constructed.According to the working conditions of high-power loads,critical parameters such as voltage,current,velocity and torque of the power grid are theoretically analyzed,calculated and simulated when high-power loads are put into operation,and complete data is obtained to ensure the effective operation of medium voltage power supply and high-load ship integrated power system.
