分层分布式输变电设备状态监测系统中,状态接入控制器(CAC)与状态接入网关(CAG)之间的数据交换是实现状态信息纵向贯通的基础。通过对电力系统远程通信协议和分布式组件技术的分析,采用简单对象访问协议(SOAP)实现状态监测数据的分布式交换,给出基于Web服务描述语言(WSDL)的状态监测数据交换服务的建模方法和过程,以确保系统的可移植性和互操作性。采用上述方法和模型,设计实现了一个状态监测数据交换实验系统,并以变电CAC周期上传状态监测数据服务为例,对系统进行了性能和负载测试,验证了该方法的正确性和可行性。
In Hierarchical Distributed Generation and Transmission Equipment Condition Monitoring System, data exchange between state access controller (CAC) and state access gateway (CAG) is the basis of longitudinal communication of state information. Through the analysis of telecommunication protocol and distributed component technology of power system, SOAP (Distributed Object-Oriented Protocol) is used to realize the distributed exchange of status monitoring data. The status monitoring data exchange service based on Web Services Description Language (WSDL) Modal methods and procedures to ensure system portability and interoperability. Using the above method and model, a system of state monitoring data exchange is designed and implemented. The performance monitoring and load test of the system are carried out with the example of the state monitoring data service of the up-conversion CAC cycle, which verifies the correctness and feasibility of the method .
