提出了一种基于以太网的分布式发电厂电气监控系统(ECS),系统由间隔层、通信层、系统层组成。间隔层完成继电保护、模拟量和开关量的采集以及断路器的控制;通信层完成所有实时数据的分类转发,并实现与集散控制系统(DCS)的接口通信;系统层实现全厂电气系统信息的集中处理,提供各种站级应用功能。结合工程实践经验,阐述了一种典型的ECS组网方案,并指出了实践中的一些特殊问题及解决方案。
An Ethernet-based distributed power plant monitoring system (ECS) is proposed. The system consists of a bay, a communication layer and a system layer. Interval layer to complete the relay protection, analog and digital switch and the acquisition of the circuit breaker control; communication layer to complete all the real-time data classification and forwarding, and to achieve and distributed control system (DCS) interface communication; system level to achieve the whole plant electrical system Centralized processing of information, providing a variety of station-level applications. Combined with engineering practice, a typical ECS networking scheme is described, and some special problems and solutions in practice are pointed out.
