Tavis Mining Highway Stability Study - Methods Overview and Sensitivity Study
This paper is a sensitivity study of highwall stability at Falkirk Mine. Since mining of the Tavis Creek will require maximizing the highwall height, this paper explores factors that influence the strength of the wall. The first part consists of a previous works review composed primarily of geology …

A new method of utilising stability study results in applying out-of-step protection to allow observability of rotor angle unstable conditions
Power system rotor-angle unstable conditions may cause undesired operation of distance relays, resulting in the unnecessary switching of lines. To prevent the possible undesired operation of distance relays, a protection type known as out-of-step blocking is used. This protection type is …

Reduced order power system models for transient stability studies
… by performing a better then real-time transient stability study. Because of the computing capacity required for a transient stability study, the study cannot be performed on the full power system. A reduced model must be used. In this thesis, various methods of obtaining reduced models for use in …
