摘　　要：提出了基于CPS统计特性的自适应自动发电控制(AGC)策略,对自适应控制系统结构和CPS/DCS控制器的设计均进行了阐述,重点阐述了可随电网结构、运行方式和实际需要变化的自适应CPS控制参数调节规律。该自适应AGC策略的设计完全面向NARI所提出的控制性能标准(CPS)控制规律,解决了NARI控制规律中参数自动整定问题,并可快速、简便地在电网公司现有的AGC系统上升级实现。借鉴引用了以经济性和指标性为主的优化控制方法。研究表明,该自适应AGC策略可在保证CPS考核合格率的同时有效减轻发电厂的调节压力。The adaptive AGC strategy based on the statistical property of CPS is presented.The structure of adaptive control system and the design of CPS / DCS controller are introduced and the adjustment rules of adaptive CPS control parameters varying according to the power grid structure,operational mode and actual requirement are detailed.The design of adaptive AGC strategy is based on the CPS control rules of NARI,automatically sets its parameters and refers to the optimal control methods based on economic and indicative performances,which can be easily implemented on current AGC systems.Study shows that the proposed strategy effectively mitigates the AGC pressure of power plants while the CPS compliance is ensured.
