完全分散式的变电站自动化系统

An Overall Automation System for Substations Based on a Completely Distributed Structure

研究了一种完全分散式的变电站综合自动化体系，对于系统结构、继电保护问题、可靠性及通信网等关键环节进行了讨论．

With a distributed structure, a new system more reliable than the conventional one for overall substation automation is described. One of the most important problems is the relay protection while the relay protection of electrical equipment at the HV side is independent of other functions such as measurement in the new system. The communication net in the substations is also discussed and an Arcnet is briefly described. The typical design of a 110kV substation is given.
