A power station is to supply four regions of loads whose peak values are 10,000 kW, 5000 kW, 8000 kW and 7000 kW. The diversity factor of the load at the station is 1.5 and the average annual load factor is 60%. Calculate the maximum demand on the station and annual energy supplied from the station. A generating station has a connected load of 40 MW and a maximum demand of 20 MW : the units generated being 60 × 10°. Calculate (i) the demand factor (ii) the load factor.

If the load is connected to the generator thgrough an inductive line and the voltage at the load side is the same as the voltage at the terminals of the generator, which of the following must be true? O A. The reactive power is flowing from the generator to the load and from load to the generator at the same time. O B. The load is disconnected, and no power is delivered to the load. O C. The load has a poor power factor and it's absorbing too much reactive power. O D. None of the other choices are correct O E. The generator is unable to produce reactive power; therefore, the reactive power is flowing from the load to the generator.
