火电机组AGC指令前馈滤波逻辑优化设计
Optimized Design on Feed-forward Filter Logic for AGC Instruction of Thermal Power Generating Unit
摘要
Abstract
Complicated and variable automation generation control (AGC)instructions of the power grid of thermal power generating unit after scaled grid-connection of wind power has caused substantial fluctuation of boiler fuel,which may bring negative influence on stable operation of the unit. Therefore,the paper studies filtering logic of feed-forward signals of AGC instructions of the coordination and control system,and analyzes transformation laws of AGC instructions and charac-teristics of thermal power generating unit objects and the control system.It presents an optimized scheme of adding a second order inertial filtering before the speed-limit filtering.Corresponding results indicate as AGC instructions change slightly it is able to avoid substantial fluctuation of fuel by weakening feed-forward output,while as AGC instruction change substantial-ly,timely and enough output of feed-forward signals can prevent large deviation of throttle pressure.关键词
