Transient Stability Analysis for Betterment of Power System Stability Adopting HVDC Controls

Incorporation of HVDC transmission subsystems in AC transmission networks has been a major change in power transmission during the last few years. This change required modifications in the performance evaluation procedures notably for load flow and stability analysis. The methodologies used for AC/DC system's load flow calculation and transient stability analysis are presented in this chapter In this thesis, the investigations are carried out on the improvement of power system stability by utilizing auxiliary controls for controlling HVDC power flow. AC/DC load flow using eliminated variable method is utilized in the transient stability analysis. Transient stability analysis is done on single machine system and multi-machine system, using different control signals derived from the AC system.
