Research On The Fuzzy Predictive Control And Its Application On The Unit Coordinated Control System

The coordinated control system (CCS) of turbine-generator unit is a typical nonlinear, time-varying, multi-variable control system. At present, the complex control system is regarded as the research direction of the control science and engineering disciplines development by the domestic and foreign-controlled experts. This paper studies the 600 MW Unit coordinated control system modeling and advanced control strategies, and the control system design, debugging, and optimization are applied in Fuzhou Jiangyin Power Company Limited, #1. Based on T-S fuzzy model, the unit load nonlinear model is established by using fuzzy clustering method. Based on the fuzzy model, the multivariable generalized predictive control method solves the large-scale, rapid load change problem. Automatic generation control (AGC) is an essential request of modern power system automatic control at present, slow response to AGC load demand is a serious problem existing in thermal power units taking part in AGC poor. The means of the improving the response to the unit CCS are applied the scheme, they assured the rapid response to AGC load demand of the power unit.
