QUESTION: 1

### Series capacitive compensation on EHV transmission lines is used to

Solution:

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.

QUESTION: 2

Solution:
QUESTION: 3

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

Solution:
QUESTION: 4

For a synchronous phase modifier the load angle is

Solution:

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

QUESTION: 5

A synchronous phase modifier supplies

Solution:
QUESTION: 6

Series capacitors on transmission lines are of little use when

Solution:

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

QUESTION: 7

Full load compensation in a line requires

Solution:

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

QUESTION: 8

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

Solution:
QUESTION: 9

Shunt capacitance in an EHV line is restored to

Solution:

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

QUESTION: 10

The reactive power transfer over a line mainly depends on

Solution:

Reactive power,

Or,
