摘要
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。
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 excellent real-time performance is selected and the model communication program is written by VC＋＋ in its Tornado compiler debugging environment. The main functions and flowcharts of analysis program are given.
