摘要:

为实现电厂各台机组负荷的经济分配,广东红海湾发电有限公司建设了一套外置式厂级自动发电控制(AGC)系统,AGC指令由原有的单台机组改为全厂的负荷指令,在接受调度下达的全厂负荷指令后,通过厂级AGC服务器进行负荷优化计算。介绍了厂级AGC系统构建、软件结构与流程,总结了厂级AGC系统的设计要点。系统投入运行后,各通道精度、负荷指令分配、变负荷速率以及一次调频响应均满足电网要求,并使电厂侧获得了每台机组的负荷分配权。

Abstract:

In order to achieve the economic distribution of load among different units in plant, Guangdong Honghaiwan Generation Company Limited launch a set of external plant level automatic generation control (AGC) system. AGC command turns from the original load command for single unit to load command for the whole plant. After acceptance of load command for the whole plant, load optimization calculation is made by plant level AGC server.  It introduces the construction of plant level AGC system, structure and process of software at plant level, and summarizes the key designing points of AGC system. After the operation of the system, accuracy of every channel, the load command distribution, load change rate and response to primary frequency modulation can satisfy the requirements of grid. The load distribution right of each unit is obtained by the plant side.
