Abstract


300MW power unit is configured DEH Control System , DEH control system directly affects the functional units safe and economic operation. Currently DEH system control logic is not perfect , there is a control deficiency , or even logical error , can not meet the requirements of the unit safe and economic operation . This article discusses the features typical DEH , DEH system of typical characteristics of objects to Zhangjiakou Power Plant Unit # 1 DEH system as the research object , the DEH original function analysis , summarize the problems , propose reasonable and feasible optimization program , focusing on the optimization of load rejection test in program design and implementation , pilot programs for primary frequency optimal design and implementation of the pilot scheme Casing Start optimal design and implementation of all tests are up to expectations.
