基于IEC61850的SF_6断路器在线监测系统的信息建模及通信实现

针对高压断路器SF6断路器状态在线监测的特点,提出合理利用IEC61850标准中逻辑节点GGIO,应用IEC61850对实际智能电子设备(IED)进行建模;断路器状态在线监测数据通过GOOSE报文传输,GOOSE采用发布/订阅模式,报文延迟不超过4ms。论述了GOOSE报文的组织方式及通信机制;选用实时性高的操作系统VxWorks,并在其Tomado编译调试环境下,运用VC++编写了模型通信程序,给出了分析程序的主要功能函数及流程图。

Information modeling and communication of SF_6 circuit breaker on-line monitoring system based on IEC61850

According to the characteristics of SF6 circuit breaker state on-line monitoring, it is proposed to fully use the logical node GGIO (Generic Input / Output) of IEC61850 in the modeling of intelligent electronic devices. The on-line monitoring data of circuit breaker state is transferred by GOOSE (Generic Object Oriented Substation Event) message with time delay less than 4 ms,which applies publish / subscribe model. Its scheduling and communications mechanism are introduced. VxWorks, an operating system by ...
