The boiler-turbine coordination system of power equipment is a complicated multi-variable control system. Researching the coordinated control system can improve the automatic degree and safe, economical operation level of power plant. The authors analyzed the peculiarity of boiler-turbine coordination and, combining the instance and feasibility of boiler-turbine, designed the boiler-turbine coordination system based on reforming sliding pressure control. In addition, the theory of boiler-turbine coordination was also analyzed. The designed controller was emulated, and the result shows the performance of reformed sliding pressure controller is better.
