Modification Of A 200MW Power Plant Simulator To DCS Mode

As a continuous producing process, safety is the most important part in thermal power. It has been proved that many serious mistakes will be made by the operators. At the same time, because higher and higher temperature and pressure are appeard in the modern thermal power plant, the operators which are in these plant shoud have more high technologies to control these devices. Since DCS is used widely in thermal power plant, what the operators faced is not many meters and operation handles, but computers. So the old style simulators are not suitable to train the operators in modern power plants.The simulator of Education Training Center of Chongqing Electrolic Company was built in 1997, and ther are many problems as follow: 1) this simulator can not be used to train operators in power plant mount with DCS; 2) Many devices can not wrok now; 3) Some devices can not be bought now. Since simulator has been playing a very important role in the training process, it is necessary to reform this system.In order to reform this simulator, some tasks have been completed as follow:1) Based on the structure of DCS, a new structure of simulation system has been built;2) The model has been modified to fit the new windows operation system.3) The control device in panel has been updated;4) The parallel running in panels and coputers has been completed.This simulator has been tesed in a few strict conditions. With this simulator, more than 300 people have been trained, and it is working steadily during this period. And the results show that the mode can reflect most dynamic characteristics.
