【Abstract】 In view of the problem of long response time and unstable control of the original coordinated control technology, a study on the coordinated control technology of Marine steam power plant is proposed. Physical structure according to the steam power plant, analyzing machine furnace energy conversion process, it can be divided into three parts, complete processing analysis, using the flow continuity equation, analysis of the boiler heat transfer principle, optimization of steam turbine power, calculating the transfer function, engine and boiler coordinated control system model is set up, using SIMULINK visualization simulation tools, design simulation experiment. The experimental results show that compared with the original technology, the new coordinated control technology can effectively shorten the rise time of the response curve, reduce the range of curve changes, and effectively enhance the coordinated control effect. It is proved that the new coordinated control technology is superior to the original one.更多还原
