摘　　要：分析了目前国内火电厂电气监控实现的方式(DCS+ECS),并指出了这种实现方式依然存在通讯数据交换的瓶颈、难于实现电气设备信息管理等高级功能。在仪电一体化火电厂监控系统架构下,提出了一种与DCS系统通过通讯技术实现数据交换的火电厂电气监控系统的实现方法。将全通讯ECS统一在DCS平台架构下,通过与DCS系统在各级网络层进行数据交换来彻底取消DCS系统的电气二次硬接线。同时,对实现这种ECS系统的几个技术要点进行了分析,即组网方式、通讯性能评估、在间隔层实现数据通讯。The current electrical control mode （ DCS ＋ ECS ） of thermal power plant in the domestic was analyzed, it is pointed out that under this mode there is bottleneck for data communication, and some advanced functions, such as electric equipment information management, were difficult to implement. Under the instrument-electric integration power plant control system architecture, an electrical control system scheme was put forward which implement data exchange by means of communication with DCS, the full communication ECS will be located on the DCS plateform and can implement data exchange with DCS at various network layers, so the electrical hardware secondary connection of DCS will be cancelled. Several technical key points for realization of this ECS were analyzed, which includes networking mode, evaluation of eommunication performance and communication in the interval layers.
