PCC-based simulation and test system of pumped storage unit

HE Feng,SHEN Zu-yi(College of Water Conservancy and Hydropower Engineering,Hohai University,Nanjing 210098,China)  
With PCC(Programmable Computer Controller) as the hardware platform and C language programming,a mathematical model of pumped storage unit is established and a simulation and test sys-tem for it is developed.The system consists of B R 2003 system,PP120 system,and PC with corres-ponding software,realizing the real-time simulation,field test and data analysis for test objectives of the hydraulic turbine.Combined with the microprocessor-based governor of pumped storage unit and applied practical parameters of a real power station,tests are carried out for verification.Results show that the system improves the real-time performance and reliability of data acquisition and transmission,providing a rapid and precise control of the governing system for pumped storage unit.
