Series capacitive compensation on EHV transmission lines is used to
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.
Phase modifier is normally installed in the case of
For the stable operation of interconnected system, the passive element that can be used as an interconnecting element is
For a synchronous phase modifier the load angle is
Synchronous phase modifier is an overexcited synchronous motor operating on no-load under wide variation of excitation. For no-load operation, δ = 0.
A synchronous phase modifier supplies
Series capacitors on transmission lines are of little use when
Full load compensation in a line requires
Full load compensation in a line requires shunt capacitors for improving power factor of the system.
Use of additional shunt capacitor can be made for increasing the capability of line as it
Shunt capacitance in an EHV line is restored to
Shunt capacitor is usually connected at load end for improving power factor and voltage.
The reactive power transfer over a line mainly depends on
