Investigation of Control Strategies for Variable-Speed Pump-Turbine Units by Using a Simplified Model of the Converters

A Novel Control Method Of Variable Speed Pumped Storage Power Plant

“…In this paper, one of plant's units analyzed and simulated as DFAM considering proposed strategy by replaced synchronous one. Important parameters about it illustrated in Tables as bellow: [14] because the torque is controlled by the electrical system, as shown in …”

Optimization of the start-up time of a variable speed pump-turbine unit in pumping mode

“…These different studies consider simplified models for the electrical system and do not take into account the converters. The modeling, simulation and analysis of the dynamic behavior of a 2 x 320 MW variable-speed pump-turbine power plant, including a hydraulic system, electrical equipment with the three-level VSIs of the converters, rotating inertias and control systems have been presented in [17]. Morel et al [18] present the selfstarting and synchronization of a variable speed unit using a double fed induction machine.…”

“…The machine section is used to start up the unit, to synchronize it with the grid and finally to control the speed and the stator reactive power of the machine by acting on the rotor currents through the right-side converter [8], [17].…”

Stability study of a mixed islanded power network

“…The power network represented in Fig. 1 is simulated using the software package SIMSEN, developed for the simulation and the analysis of power sys tems [4], [5], [6]. The modeling of the 3 power plants are presented below.…”
