IMPROVEMENT OF FREQUENCY START OF HYDROELECTRIC PUMPED STORAGE POWER PLANT IN THE PUMPING MODE
Abstract
The general mathematical model of the improved method for starting the hydraulic unit makes possible the rotation of a conventional system of relative units in projections of generalized synchronous machine vectors on the orthogonal coordinate system axis focused on its magnetic field of the rotor. This general mathematical model contains mathematical model of synchronous generator, synchronous motor and control unit.
On the basis of this mathematical model the simulation (computer) model of the improved method for frequency start at hydro pump mode from a nearby hydroelectric unit is created. Through this simulation model the electromagnetic and mechanical processes of the method being applied to start hydraulic units installed on the PSP Kiev in Ukraine are investigated and evaluated
