Extracted text: A three-phase, 60-Hz, 500-MVA, 11.8-kV, 4-pole steam turbine-generating unit has an H constant of 6 p.u.-s. Determine: (a) »syn and wmsyn; (b) the kinetic energy in joules stored in the rotating masses at synchronous speed; (c) the mechanical angular acceleration a, and electrical angular acceleration a if the unit is operating at syn- chronous speed with an accelerating power of 500 MW.
