Abstract The expert workstation is an important part of the maintenance system of hydropower sets , which is an important tool for the experts to carry out information inquiry , analysis and diagnosis as well as debugging and setting the online monitoring systems. Currently, the workstation commonly uses the portable computers with special software and the operations need to be carried out on the power station site, which is not conductive for remote fault diagnosis, so the networking is needed. The architecture of the networked workstation of HOMS is designed according to the function requirements. The database design is described and the main functions and implementation methods are introduced. The networked workstation is built on an Internet/Intranet open structure and the networking operation of the various functions of workstation is implemented. The networked workstation has been put into service successfully in the Gezhouba Hydropower Plant. The application result shows that the networked workstation is featured and practical and provides significant support for the remote monitoring and fault diagnosis for the hydropower sets with good prospects.
