we have one pumping station and 4.6 MW 7 no.s synchronous motors.so there is no required HT capacitor to improve power factor.But we have two no.s of 25 Mva power transformer connect to distribute the power for motors connect with 220 kv line.So i have required the HT capacitor to improve power factor at HT side i mean power transformer bus side.So please suggest how much HT capacitor banks required for same.

(1)The demand for electricity , the amount of renewable generation available, the amount of fossil fuel generation available and the cost of the fossil fuel generation are shown in table below period(hrs) demand(MW) renewable (MW) fossil- fuel(MW) cost of fossil fuel(MW) 00.00 - 01.00 2000 1800 2000 30 01.00 - 02.00 2300 2500 2000 30 02.00 - 03.00 2500 2700 2100 45 03.00 - 04.00 2900 3100 2100 50 04.00 - 05.00 2700 2600 2500 45 05.00 - 06.00 2400 2000 2700 50 06.00 - 07.00 2200 1800 2000 36 07.00 - 08.00 2100 1600 2000 36 Assuming that the renewable generation incurs zero cost, determine an optimal generation schedule(specifying the amount of renewable generation and fossil fuel generation used in each period, the cost for each period and the overall cost for 8 hours.)

In 110V DC supply,if a closed circuit gets open, How can we identify the voltage which is measured after the resistor(4KOhm) which is open with negative.it shows 55V +ve when measured, also the actual positive source is 55V +ve .Because there is no voltage drop in open circuit. How can we identify whether this is the voltage which is series with the resistor or the DC source direct +ve.
