| Abstract: | Taking Guixi power plant 640 MW ALSTOM ultra supercritical unit as an example,thepaper introduces the turbine auxiliary system start-stop automatic control strategy design.Controlfunction uses a hierarchical structure,dividing into the equipment level,cell level and functionalgroup level.Various functions are discussed.Turbine auxiliary system control strategy includes asequence control and analog process control.According to the different control variables,controlmethods are applied.Analog regulating system in addition to a manual regulation,also designed theautomatic standby status and automatic regulation of the state.Turbine auxiliary system running result proves the validity and rationality of the control strategy. |
