Power System P7

Zero Voltage regulation is possible with-

Assertion: Nominal π representation is preferred in load flow study.

Reason: There are only two unknown variable voltage in Nominal π.

Ferranti effect is observed in-

1. Overloads

2. Overvoltages

3. Off peak loads timings

4. No load times

Compensation of Ferranti effect is appying x as load. x is?

Locus of Receiving end powers P and Q at constant valuea of Sending and Recieving end voltages, is-
