The power generated by two plants are: P1 = 50 MW, P2 = 40 MW. If the loss coefficients are B11 = 0.001, B22 = 0.0095 and B12 = –0.0005, then the power loss will be (IES 1997)
5.5 MW
6.5 MW
4.5 MW
8.5 MW
In terms of power generation and Bmm coefficients, the transmission loss for a two-plant system is (Notations have their usual meaning) (IES 2000)
P21B11 + 2P1P2B12 + P22B22
P21B11 – 2P1P2B12 + P22B22
P22B11 + 2P1P2B12 + P12B22
P21Bn + P1P2B12 + P22B22
Two power plants interconnected by a tie-line as shown in the below figure have loss formula coefficient B11 = 10–3MW–1. Power is being dispatched economically with plant ‘1’ as 100 MW and plant ‘2’ as 125 MW The penalty factors for plants 1 and 2 are respectively. (IES 2001)
