Study on Hydroelectric Generating Unit on-line State Monitoring System Based on Virtual Instruments

In order to implement the state overhaul for hydroelectric generating units, it is necessary to realize the state monitoring. Considering the diversity and complication of the state monitoring, items and solution based on PXI instrument and LabVIEW of on-line monitoring are rationally selected. The realization of on-line real-time monitoring of the hydroelectric generating units by the state monitoring system through collection, processing and analysis of status values is described, which will increase the efficiency of the units greatly. The system is applied in the state overhaul for the hydroelectric generating units.
