DESIGN AND IMPLEMENTATION OF AN INTERNET BASED REMOTE MONITORING AND DIAGNOSIS SYSTEM FOR HYDROELECTRIC GENERATING SET

To ensure secure, stable and economic operation of hydroelectric generating sets, it is necessary to realize the monitoring and fault diagnosis for them. Under the environment of Internet and Windows and using network resource, PXI, MXI-3 and DataSocket technology, a remote monitoring and diagnosis system for hydroelectric generating sets is designed by use of easy to expanded Client/Server mode The architecture of this system, the constitution of its hardware and software and the functions of this system are described in detail. With this system the data acquisition, analysis and processing of the signals of hydroelectric generating sets are implemented, the fault diagnosis of the generating sets can be performed through Internet. This system is applied to actual hydroelectric generating set and the operation experience shows that the designed system is flexible and expandable and possesses good real-time performance.
