Installation of capacitors at suitable locations and of optimum size in a distribution system results in

A short capacitor used in power system for VAR compensation is operated at 98% of its rated frequency and 95% of its rated voltage. The VAR supplied by shunt capacitor (as compared to its rated capacity) is

A 250 MW, 60 Hz turbine generator set has a speed regulation of 5 percent based on its own rating. The generator frequency decreases from 60 Hz to a steady state value of 59.7 Hz. Determine the increase in the turbine power output in MW.

Two generating units rated for 250 MW and 400 MW have their droop settings of 6.0% and 6.4%, respectively. The units operate in parallel at 50 Hz at no load. Determine the load taken by each unit for a total load of 500 MW. Neglect losses and the dependence of load on frequency.

Two generators rated 250 MW and 400 MW are operating in parallel. The droop characteristics of the governors are 4% and 6% respectively.if a load of 450 MW be share between them. What will be the system frequency? Assume nominal system frequency is 60 Hz and no governing action.

A 3 – phase overhead line has resistance and reactance per phase of 5 Ω and 20 Ω respectively. The load at the receiving end is 25 MW at 33 kV and a power factor of 0.8 lagging. Find the capacity of the synchronous condenser required for this load condition if it is connected at the receiving end and the line voltages at both ends are maintained at 33 kV.
