The major topics in Power Systems for Gate 2016 are as follows:

The major topics in Power Systems for Gate 2016 are as
follows:

A.

__Transmission and Distribution__
1.

__overhead transmission lines__
·
memorize the expressions for Inductance
and Capacitance for both Single Phase and Three Phase Lines.

·
practice some problems based on this
which involve the computation of GMD and GMR.

2.

__modelling of Short and Medium Transmission Lines__
·
Long Transmission Lines is not much important
in Steady State Analysis and Short Transmission Line is most important.

·
A,B,C,D Parameters of the line

·
power expressions in terms of A,B,C,D

·
approximate voltage regulation in Short
Transmission Line which is same as Transformer.

3.

__Surges__
1.
memorize
the thevenin equivalent circuit for analysis of surges to calculate the
Transmission and Reflection Coefficient for Voltage

2.
Voltage Control and Power Factor Correction

__4. UG Cables__

1.
insulation resistance

3.
capacitance model for 3 phase 3 core
belted cable which has core capacitance and sheath capacitance.

4.

__Overhead Insulator__- voltage distribution across different
discs can be asked
- remember
the expression upto 3 discs.

6.

__Distribution Systems__- applying
KVL and finding the currents in different branches.
