摘要
介绍了在网控系统中配合调度中心实现自动发电控制(AGC)的几种方案;包括传统的硬接线方案及在综合自动化系统中的通信方案。分析了这些方案的优缺点,并提出了今后的发展前景,即通信方式必将替代硬接线方式,厂站端系统的功能越来越强,扮演着越来越重要的角色。
Method to implement AGC in power plant to cooperate with the dispatching center was introduced, including the traditional connection scheme and the communication scheme in network control system. The advantage and disadvantage of the method was also descried. The method in the future to implement AGC in NCS is predicted.
