The variable frequency load control method is used to realize the stable operation of the ship power grid,which can effectively solve the problems of overload of the main engine and low-frequency oscillation of the power grid caused by sudden load increase of the ship power grid,especially for large electric propulsion ships with more variable frequency loads.Based on the techniques of ship power grid and variable frequency load,this paper designs a variable frequency load control system to re-alize the stable operation of ship power grid,describes the overall structure scheme of the system,and gives the calculation method of target load power and load real-time output power.The variable frequency load control of this system is highly effec-tive,which can avoid large power or frequency fluctuations and power or frequency out of limit generated by the power grid,improve the service life of the unit,and achieve safe and stable operation of the power grid.It has a certain reference signifi-cance for the design of the ship integrated power system with more variable frequency load.
