Research On Monitoring And Controlling System Of Power Plant Based On Fiber Network

With the development of the science, the computer is used widely. in the power plant of ship, it is a main trend that the computer is used to monitor and control the power plant, it can develop the credibility of the device controlling, reduce the accident, lower the work intension, improve the dynamic response attribute, make the device in best state in all time, working with the measure system, control and implement system, safety system, integration monitoring and controlling system can deal with the data, control and adjust the object, it is very important in the engineering.Because the condition of controlling the actual power-plant is not available, so a emulation-program of the steam generator is used to simulate the actual power-plant, on the base of this, a emulation-control is finished.First, the part network of the power plant monitoring and controlling system is built and adjust, then the monitoring and controlling system is connect with the ship power plant simulate system, through the simulation, it can achieve the emulation- control.A network communication program base on the Socket is developed, at the same time, in order to increase the speed of transmission and reduce the collision and block in the network, the way of data compressing base on garrison is used, it can transmit more data than before.In order to control the steam generator, a self-adductive fuzzy controller is designed basis of the attribute and requirement of the steam generator, and finishes the simulation of the controlling, the result of the fuzzy controller is better than that's PID controller.At last, the software of the power plant monitoring and controlling system is programmed, it can monitor and control the power plant well, the integrating software is in good visualize and can be manipulated easily.
