Power Systems A load centre is at an equidistant from the two thermal generating stations G1 and G2. The fuel cost characteristics of the generating stations are given by F1 = a + bP1 + cP²1 F2 = a + b P2 + 2cP²2 Where P1 and P2 are the generation in MW of G1 and G2, respectively. For most economic generation to meet 300 MW of load, P1 and P2 respectively, are 150, 150 200, 100 100, 200 175, 125 150, 150 200, 100 100, 200 175, 125 ANSWER DOWNLOAD EXAMIANS APP
Power Systems The maximum efficiency of modern coal fired steam steam raising thermal power plants is restricted to about 0.35( a low value), mainly because of high energy loss in condenser high energy loss in boilers low alternator efficiency low steam turbine mechanical efficiency high energy loss in condenser high energy loss in boilers low alternator efficiency low steam turbine mechanical efficiency ANSWER DOWNLOAD EXAMIANS APP
