Question #14 - Figure 7 a. Figure 7 above shows a typical daily load demand curve of the United Kingdom, for various times of the year. i. By labelling the curves from 1-4, from the uppermost to the lowest respectively, state and explain which time of year would facilitate generator maintenance ii. Estimate the maximum base load demand on the system. iii. Given that you have available, hydro plants using run-of-the-river and pump storage, indicate, giving reasons how these plants would be used in the mix of generation to meet the system demand. iv. How would operating cost and operation time influence your decision in the despatch of generation to meet the peak demand? b. Distinguish, using relevant diagrams, between short and medium transmission lines. c. Briefly explain the importance of short and open circuits tests carried out on power transformers.
