分析了现有设备状态监测系统相关建模和通信技术规范的不足,提出了主、子站统一按IEC61850建模和通信的思路。根据设备状态监测系统的特点,论证了Web Service技术用于IEC61850通信映射的可行性,并介绍了具体的实现方法。对设备状态监测系统通信涉及的IEC61850网关建模、主/子站冗余通信、多子站并发通信、配置文件源端维护等关键技术进行了论述并给出了实现方案。基于开发的原型系统进行了功能和性能测试,结果证明所提出的设备状态监测系统通信方案是可行的。

The deficiencies of existing modeling methods and communication technical specifications for the equipment status monitoring system are analyzed and it is proposed to apply the concept of unified modeling and communication according to IEC61850 for both master and slave substations. The feasibility of applying the Web Service in IEC61850 communication mapping is verified according to the characteristics of equipment status monitoring system and the corresponding implementation is introduced. The key technology of communication involved in the equipment status monitoring system are introduced,such as IEC61850 gateway modeling,redundant communication between master and slave stations,concurrent communication of multiple slave stations,configuration file maintenance at source-end,etc.,and the implementation scheme is given. A prototype system is developed for the functional and performance tests and the results show the proposed communication scheme is feasible.
