Abstract

The direct torque control theory was applied to achieving variable frequency control of the main seawater pump. Under the premise of ensuring the system cooling capacity to meet the requirement of heat load, the pump speeds were varied with different thermal load and sea water temperature, and the modeling and simulation of whole system were completed by using MATLAB/Simulink software. Simulation results show that the proposed system can adjust the speed of seawater pump automatically according to the different thermal load of main engine and different seawater temperature to reach a good speed and torque dynamic response. In addition, the energy consumption can be effectively reduced as compared with power frequency mode.
