Abstract :
The concept of all-electric ship and of integrated power systems is being matured and developed in the navy forces throughout the world. Therefore, it is inevitable the use and development of multiphase electrical motors. Recently, British Navy has delivered its last “Daring” class destroyer with 15-phase electrical motor. The detailed mathematical model of five phase Interior Permanent Magnet Synchronous Motor (IPMSM) is developed in this paper. This motor is the main electrical motor of a ship. The five phase model is developed using phase variable model which is then transformed into two fictitious orthogonal sets termed as dq and xy0. In addition, a speed-controlled PM synchronous motor drive, which allows the simulation of the navigation conditions of a small warship, is presented. The ship control system explores the strategies of the constant (δ = 90°) torque angle control and of the maximum torque per ampere. The PSCAD/EMTDC program is the one used in the implementation and simulation of the speed-controlled PM synchronous motor drive and the control strategies.
