A pumped storage facility uses a 6.6 kV, 60 Hz, 4200 kVA, 3360 kW, 10 pole, three-phase synchronous machine, with a synchronous reactance of 1.13 pu. Assume a cylindrical rotor. The hydro turbine is rated 3500 kW. All losses are neglected. 1. Hydro generator capabilities (a) Compute the hydro turbine speed to obtain a 60 Hz output; the range of the power factor of the generator; the rated line current. Compute the value of synchronous reactance in ohm. (b) Draw the per-phase equivalent circuit. Assume Y-connected generator windings. Present and explain the functions of the hydro turbine and generator controls.
