The Study And Practice Of Marine Power Station Physical Simulation System

Along with the development of simulation technology and continuous enhancement of ship automatism degree, to set up the special simulation and training system is imperative. The simulation technology will be one of the most efficiency artifice in the research of the static state and dynamic state process of ship electric power system gradually. Usually, the simulation method using in the electric power system is: physics simulation, mathematics simulation and so on. The equipment for mathematics simulation is cheap and agility, but it can't reach enough simulation precision for the complex interior process. Adopting physics simulation not only can study the process of the static state and dynamic state, but also, it is verisimilitude, convenience for measure and can reach a very wide range of parameter modulation.This passage has six chapters in total, firstly it intrduces the emulational principles of the marine power station physics simulation system, compares the simulation of diesel engine using asynchronism electromotor and Transducer to DC electromotor. Then it concludes that the first emulation mode is the developing current in the future. The core of this system is Generator Paralleling Controller(GPC) of DEIF. It can realize the basic controls of marine power station with Programmable Logic Controller(PLC) and Transducer which include automatic synchronization and regulation of frequency and load. Then it introduces the basic composing and functions of this system, and researchs the representative part. After mensuration of the simulation system in practice, we find that its performance target can satisfy the criterion completely. After debugging in laboratory and lucubrating the simulation system, we design the protection of eliminating excitation tache. Along with the developing of excitation control technology,computer and electron technology adopting digital excitation adjustment to replace analog excitation adjustment is a inevitable current. For the above reason we design excitation regulator based on DSP.
