I wanted to get a clear idea of how bus reactors and line reactors help the overall performance of power system and how they are connected in the bus-bar or in the transmission line. Thanks.
Line Reactors are current-limiting devices suppressing rapid changes in current and limiting current surges.
Shunt reactors which are used for controlling the bus voltage of sub station are known as bus reactors. They maintain bus voltage counteracting the over compensating effect of capacitance.
Another aplication of Serie-Line Reactors (On Transmission Lines) is Limiting Short-Circuit Current (Fault Levels).
Please could you read the book of Hadi Saadat of power systems in hp Parameters of transmission lines...her you find the answer-.
Not all line reactors are series connected. While it is true that reactors may be used in series (to limit fault currents), EHV lines frequently are equipped with shunt reactors. Their purpose is to cancel some of the effects of the line's shunt capacitance. EHV lines frequently have bundled conductors in order to keep the electric field strength at the surface of the conductors of the line from being excessive. This also helps reduce the field strength at the edge of the right-of-way (another EHV line design concern). Line shunt reactors help to manage the voltage on the system by minimizing the voltage change that occurs when the line is switched in and out of the system.
We have to go the basics of compensation namely series and parallel and their applications. Once you are clear on that you yourselves will be able to list the applications and come out with their applicability.
