1) Why do we require Transmission inter connections?

2) With a neat circuit diagram describe the operation of single phase full wave voltage source converter and draw the relevant wave forms for ac voltage, ac current.

3) prepare down the advantages and disadvantages of current source converters over voltage source converters.

4) With neat diagrams describe the variations of voltage stability limit of a radial line with load and load power factor and describe how you extend the limit by reactive shunt compensation.

5) With a block diagram describe the functional control scheme for the TSC-TCR type static var generator.

6) Design the block diagram of basic static var compensator and derive the expression for the variation of amplitude variation of the terminal voltage against amplitude variation of power system voltage.

7) Compare the STATCOM and SVC taking at least six points into account

8) With a neat circuit diagram describe a basic Thyristor Switched Series Capacitor scheme and describe the operation.

9) prepare down the limitations on loading capability of transmission assets.
