Test: Compensation Techniques, Voltage Profile Control & Load Frequency Control of Power Systems - Question 1

Series capacitive compensation on EHV transmission lines is used to

Detailed Solution: Question 1

With series capacitive compensation, the net transfer reactance of the line will be X = (XL - XC) due to which the power transmitted from sending to the receiving end is increased. Thus, it will improve the steady-state stability of the system.

Test: Compensation Techniques, Voltage Profile Control & Load Frequency Control of Power Systems - Question 2

Phase modifier is normally installed in the case of

Test: Compensation Techniques, Voltage Profile Control & Load Frequency Control of Power Systems - Question 3

For the stable operation of interconnected system, the passive element that can be used as an interconnecting element is

Test: Compensation Techniques, Voltage Profile Control & Load Frequency Control of Power Systems - Question 4

For a synchronous phase modifier the load angle is

Detailed Solution: Question 4

Synchronous phase modifier is an overexcited synchronous motor operating on no-load under wide variation of excitation. For no-load operation, δ = 0.

Test: Compensation Techniques, Voltage Profile Control & Load Frequency Control of Power Systems - Question 5

A synchronous phase modifier supplies

Test: Compensation Techniques, Voltage Profile Control & Load Frequency Control of Power Systems - Question 6

Series capacitors on transmission lines are of little use when

Detailed Solution: Question 6

Correct Answer :- a

Explanation :  If the load var requirement is small, series capacitors are of little help.

Test: Compensation Techniques, Voltage Profile Control & Load Frequency Control of Power Systems - Question 7

Full load compensation in a line requires

Detailed Solution: Question 7

Full load compensation in a line requires shunt capacitors for improving power factor of the system.

Test: Compensation Techniques, Voltage Profile Control & Load Frequency Control of Power Systems - Question 8

Use of additional shunt capacitor can be made for increasing the capability of line as it

Test: Compensation Techniques, Voltage Profile Control & Load Frequency Control of Power Systems - Question 9

Shunt capacitance in an EHV line is restored to

Detailed Solution: Question 9

Shunt capacitor is usually connected at load end for improving power factor and voltage.

Test: Compensation Techniques, Voltage Profile Control & Load Frequency Control of Power Systems - Question 10

The reactive power transfer over a line mainly depends on

Detailed Solution: Question 10

Reactive power,
