The System Design Of Ship Simulation Power Station Monitoring And Virtual Manipulation

With the continuous development of ship large-scale, automation andpower consumption, as the core of the ship power systems, the ship powerstation is more complex. It is very necessary to research new technology ofship power station. Due to the direct application of real ship power station ishigh cost and risk，so built a highly realistic simulation experiments shippower station, what can do monitoring research and training will has a veryimportant practical significance.Traditional ship power station simulator focus on pure virtual orsemi-physical simulation， namely to establish a virtual power station on acomputer system or set up a distribution system in the lab. But their status aregenerated entirely by computer simulation， the operation is lack of realism,and the training experience is not good. Its dynamic response is different fromthe actual plant and the study of monitoring and optimization is not an idealexperimental platform.Applied the similarity theory, in order to ship on dc motor-generator onthe physical simulation, isolated networks of ship power station simulation(ship) power system of power supply. To automatic paralleling, automaticcontrol, protection, programmable logic controller as the main controlmethod， and the Ethernet as the main communication means. With thecontrol layer， device layer， the management to achieve the detection alarm，control and security of the simulation of ship power station.This paper describes the major role of the simulation system automationpower station and on this basis， proposed to implement the physical plantautomation control system simulation function of each part of the monitoringthrough detailed analysis. Power station monitoring system is mainlycontrolled by the PLC program and the monitoring computer monitoringprogram components， including turbine start-stop control， and vehiclecontrol， Frequency Modulation of control， power systems and generator sets automatic detection circuit， power system protection， generator setstatus real time monitoring and other functions. We select the constant powerload model as experimental subjects in the physical simulation platform.Our country is a maritime country， a large number of maritime collegestudents need to be pre-job training and numerous job skills are needed toimprove crew training every year. This article will apply configurationtechnology and network technology to the simulation of ship power， developpure software development ship power station virtual operating system， ithas good man-machine interface， high flexibility and easy to do secondarydevelopment， with a very good application value.
