中文摘要：

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。

英文摘要：

The condition monitoring data exchange between the condition acquisition controller （CAC） and condition acquisition gateway （CAG）is the basis of vertical interconnection of condition information in the condition monitoring system with hierarchical and distributed structure for power transmission and transformation equipment. Based on an analysis of the remote communication protocol for power systems and distributed component technology, the implementation method based on the simple object access protocol （SOAP） of distributed data exchange, the modeling method and process based on Web services descriptive language （WSDL） of data exchange services for condition monitoring are given. A testing system for condition monitoring data exchange based on the above method and model has been developed, and put through performance and load test with the cycle upload service of condition monitoring data for CAC of power transformation equipment as an example. The validity and feasibility of the proposed models and methods have been proved.
