View answer & solution
Shunt capacitors supply leading reactive power locally, offset the lagging VAr of inductive loads, raise power factor and cut kVA-based tariff penalties.
View answer & solutionStation capacity is set by expected maximum demand, reserve margin and future load growth.
View answer & solutionAnnual average load equals total electrical energy supplied during the year divided by the total hours in that year. Therefore Average Load = annual kWh/(365×24), which is option D.
View answer & solutionD — The load is used more uniformly. Load factor = average load / maximum demand; a high value means the plant is well utilised with a flatter load curve.
View answer & solutionAmong the listed conventional choices, a thermal power plant has high operating cost because it continuously consumes large quantities of fuel and requires fuel handling, ash handling, boiler operation and significant maintenance. Hydroelectric/solar plants have very low fuel cost.
View answer & solutionCold reserve is generating capacity that exists but is not ready for immediate use; it requires startup and synchronization before it can carry load. This contrasts with spinning/hot reserve, which is already running or immediately available.
