Three thermal generating units are operating in parallel at 50 Hz sharing 600 MW load equally and have following rated capacity (Pr) and speed regulation (R) values: Unit-1: Pr=450 MW, R=5.4% Unit-2: Pr=400 MW, R=1.6%; Unit-3: Pr=500 MW,R=4%; Analyze the following new loading situations by comparing the operating frequency and load sharing when supplying a total load demand of (i) 400 MW (ii) 700 MW. Assume free governor operation and rated frequency of 50 Hz.
