Simulation Study on Key Control Strategy for Ultra Super Critical (USC) Power Generation Unit

摘要：

Super critical (SC) and Ultra-super critical (USC) power generation units with large capacity, high parameters, high efficiency and good environmental performance will be being key units of coal fired power industry. Safety and stability of these units are preconditions for that of large grid. And the automatic control system and control strategy with good performance are the basis for safety and stability of unit. SC and USC are multi-inputs, multioutputs system with strong coupling and nonlinearity. So deeply study via simulation on control scheme for SC and USC power units is necessary and significant. This paper first introduces in brief the currently used typical control strategies and its application results for SC and USC units. And optimized control strategies based on boiler dynamic intelligent input rate forward and nonlinear control technology are proposed in this paper. The simulation study on platform based on EDPF-NT plus virtual DCS and USC power unit mathematical model are made. The simulation results show that the optimized control strategies proposed can improve effectively performance of control system for SC and USC power units.
