Proposing a Rule for VSC-HVDC Optimal Placement to Improve Transient Stability of Power System [PDF]
International Journal of Research and Technology in Electrical IndustryTransient stability indicates the system's ability to dampen the rotor oscillations of synchronous generators after severe faults. The transient instability causes considerable damage to the generator and reduces the production capacity in the network ...
