Plant-level Real Time Information System of Tianhuangping Pumped Storage Power Plant
Jie Xiang · Hydropower Automation and Dam Monitoring · 2006
The plant-level real time information system of the Tianhuangping Pumped Storage Power Plant concretizes the data from 5 monitoring and control subsystems, and forms 2 long time history databases, one storing 30 000 tags with at least 1 s resolution, and another storing all events from the operator stations of the distributed control system. Every manager can make use of the data in the manner of process display, trend curves, customized logs, Excel spreadsheets,or random property filtration and order for the events. The plant-level real time information system offers a platform for integrating the data from all monitoring and control subsystems. The utilization rate of the data is raised, and the automatization and information construction of the pumped storage power plant is accelerated.
