Hydraulic balancing of the cooling water system of a pumped storage power plant

The paper focuses on the Cooling Water System (CWS) of Petrimanu Pumped Storage Power Plant, within a complex hydropower development on Lotru River in Romania. A numerical model of the above CWS is calibrated upon existing data and fits a pressure driven analysis in EPANET, through emitter coefficients attached to outlet-nodes. CWS physical components that do not exist in EPANET are replaced by equivalent throttle control valves. The final goal is to propose a hydraulically balanced configuration for the studied CWS under normal operation, then to analyze the CWS behavior under critical operation conditions.
