Two SGs are supplying a load by Pioad with 0.9 PF lagging. Gi has a no-load frequency of 54H2, and a slope Spi=1.1MW/Hz. G2 has a no-load frequency of 51HZ, and a slope Spr-1.1MW/Hz. If the system frequency is 50HZ: 1. How much power is supplied by each generator? 2. What is the load power Pload? 3. Draw the house-diagram for this system. 4. Find the system frequency, if the governor set points on G1 are decreased by 1Hz.
