Integrated Control Curves of Combined Diesel Power Plant Using Numerical Simulations

To optimize the general performance of the combined diesel marine propulsion plant that works under the one shaft propulsion mode or the three diesel engine propulsion mode, the integrated control curves of the engine speed vs. the CPP pitch for these two special operating modes are investigated through a computer-aided simulation. Firstly, mathematical models of the main components in the CODAD propul- sion plant are established and integrated to represent the whole system. Next, based on these mathematical system models and through numerical simulations, the procedure of hull-propeller-engine matching is applied, and a general design concept for the integrated control curves is introduced. The results of sea trials successfully validate the proposed design concept.
