Design of Steam Turbine digital electro -hydraulic control system Simulator

Along with the fast development of the power system, DEH has become the essential control system for steam turbines, especially for large steam turbines. In this paper, DEH system simulator of steam turbines is presented, which is based on the practical requirement of steam turbines in power plant. Under simulating steam turbines' adjusting character, DEH system simulator of steam turbines can substitute steam turbines to perform communication with DEH system. During working, the simulator can dynamically show running parameters and other information, such as switch amount information. Not only the design of simulator's hardware and software, but also it's function of anti-disturbance are introduced in detail. The circuit is simple in design and easy to use. This simulator has higher security and universality which can also save time, and there are certain development prospects.
