Simulation on the Dynamic Characteristic of Marine Saturated Stream Turbine

The paper presents the real-time entire working condition model of capacity and speed of saturated stream steam turbine. This model, based on the conservation laws and the physical property of steam, take the influences of compressibility of steam, the actual expansion process in turbine and the variable working condition property of regulation stage into consideration. The simulation results shows that this model features high steady state accuracy and reasonable dynamic trends, and has been successfully applied to a marine nuclear-powered equipment simulator.
