摘　　要：火电机组厂级负荷优化分配是降低发电成本研究的重要内容。在厂级负荷优化分配理论研究的基础上,该文提出了一种基于Ovation DCS平台的负荷控制方式。设计了基于Ovation DCS平台的厂级AGC负荷优化分配的整体架构,提出其通信方式与编程模式,并设计了外挂系统硬件,通过Modbus协议实现单片机与Ovation DCS通信;设计了负荷优化分配模块软件架构,给出了不同运行模式下的功能要求。The optimal load distribution of power plant is an important part of reducing the cost of power generation. A load control method based on Ovation DCS platform is proposed based on the study of the optimal load distribu- tion in power plants. The overall architecture of AGC plant load optimization distribution based on Ovation DCS plat- form is designed,and the communication mode and programming mode are proposed. The hardware of the external system is designed to realize communication between MCU and Ovation through Modbus protocol. The software archi- tecture of load optimization distribution module is designed,and the functional requirements of different operation modes are given.
