347Electric Power Production and Transmission Simulation
is modeled as two-mass (plus SG as the third mass). The scope Turbine gives the
opportunity to observe the speed deviations of turbine masses and SG from the syn-
chronous speed and the elastic torques between masses 1–2 and 2–3, and the scope
Grid shows the voltages and currents of various elements in the main circuit.
Before the start of simulation, with the help of Powergui, the command Load
Flow and Machine Initialization/Update Load Flow is fullled. For SG, in the eld
Bus type, the option P&V generator is chosen for active power equal to 0. It is made
to start simulation from no-load ...
