چکیده
It is very important, to optimize of clean electrical energy by employing of variable Speed pumped storage power plant (VSPSP). Variable speed machines are used extensively in wind power plants and pumped storage power plants. Therefore, the advantages of this technology are including: stability, reliability, fast dynamic responses, frequency control and high efficiency of power system. By using doubly fed asynchronous machine (DFAM) technology and the modern equipment (Cycloconverter or multilevel voltage source converters) the mentioned purposes will be achieve. In this paper, technical investigation& comparison between the whole of PSP’s drives methods is presented then a VSPSP’s unit is modeled and simulated by Direct Torque& Flux Control (DTFC) technique and two level voltage source converters (2LVSC). The results of simulation for one unit of 250 Mw pumped storage power plants have been presented. Key-Words: Doubly Fed Asynchronous Machine (DAFM), Two-Level Voltage Source Converter (2LVSC), Direct Torque& Flux Control (DTFC), Variable Speed Pumped Storage Power Plant (VSPSP)
