介绍了梯级水电站自动发电控制 (AGC)的实现原理和主要的控制运行方式———频率控制方式和功率控制方式。并根据三峡梯级水电站具体情况阐述了AGC需要考虑之处。此外 ,描述了三峡梯级AGC调度系统中信息的流向。最后指出 ,在设计计算机监控系统AGC功能时 ,需结合电站特点、发电机组的特性及整个水利枢纽的特点与调度要求 ,本着简洁、实用的原则 ,适当做一些特殊的技术处理 ,这样才能取得较为理想的运行效果
This paper introduces the realization principle of AGC and the main control mode of operation --- frequency control mode and power control mode. According to the specific conditions of the Three Gorges Cascaded Hydropower Station, the AGC needs to be considered. In addition, the flow of information in the Three Gorges cascade AGC scheduling system is described. Finally, it points out that when designing the AGC function of computer monitoring system, we must combine the characteristics of power station, the characteristics of generating units and the characteristics and dispatching requirements of the whole hydro-junction with the principle of conciseness and practicability, and properly handle some special techniques so as to obtain The ideal operating results
