Monitoring efikasnosti hidroelektrana kroz parametre SKADA sistema

Modern approach to the modernization of the power generation capacities in the hydropower sector of PE Electric Power Industry of Serbia (EPS) is seen through intensive rehabilitations and building new hydropower plants (HPPs). Although these priorities are defined by long-term investment plan, there are also improvements that are seen through the optimization of the operational regimes of HPPs. EPS technical expert team, after several months of adjustment and investigation has prepared monthly reports with the operational parameters of the HPP. In this paper, as an example, investigated parameters and results for one particular aggregate of the HPP Iron Gate 1 (ser. Đerdap 1/ rom. Portile de Fier I) are presented. Generally, in the current phase of investigation, monthly report is prepared which includes selected parameters that are archived (such as headrace and tailrace water level, the aggregates’ power and discharge) and based on data from the hill charts, losses in pipeline, generator etc. output parameters are defined. Output parameters which are considered as important for the presentation are efficiency of the turbine, generator, hence aggregate, and losses in the operational regimes with the elevation lower than the maximum headrace level. Basic parameters of the aggregates, and generally HPPs’ operational regimes, are retrieved through SCADA system, averaged on minute time intervals, and presented for the one month period.
