The analysis and experimental assessment of the transient behaviour of marine and off-shore electromechanical systems
This thesis is concerned with the development and testing of a dynamic simulation program for isolated, compact power systems of the type found in the marine and, off-shore environments. The modelling of electrical machines and their controllers is presented; the modelling of prime movers and governors is considered in detail and representations are proposed for the various driver; and loads encountered in these systems. The significant non-linearities in the systems are fully represented, A test procedure applied to an off-shore system is described and test results are presented. These are compared to simulated results for system and prime, mover responses to validate the simulation procedure adopted. In additions other validation procedures using data supplied by manufacturers are presented. These validation procedures are used to justify the mathematical representations of the, various subsystems and also to validate their co-ordination to form a complete system model. Results for a range of system studies are presented to indicate the range, flexibility and versatility of the overall simulation program.
