Paper Title
Development of Graphical User Interface to Monitor the Rotor Angle Stability Due to System Cascading Collapse

Abstract
Power system dynamic security assessment and control is becoming more challenging task in the transfer capability determination due to several new constraints, obligations and challenges that need to be encountered by the utility. Dynamic response of a power system plays an imperative role in the analysis of system stability and blackout events that usually caused by the impact of enormous and unforeseen occurrence of fault, unexpected generation and load outages, disconnection of transmission lines and abrupt disengagement of loads. Therefore, this paper proposes a computational realistic algorithm in order to monitor the stability of generator rotor angle due to the impact of contingency event to the power system. The event of transmission line tripping is known as one of the major factors that could contribute to power system instability. Due to this condition, this paper proposes an intelligent monitoring system by using graphical user interface (GUI). The GUI is programmed to provide early detection to the system utility prior to any major disturbance to the power system. The computation of rotor angle stability entails an essential numerical formulation derived from the fault condition. The IEEE Reliability Test System 1979 (RTS-79) is used to validate the robustness of the proposed methodology in monitoring the generator rotor angle due to the effect of transmission line tripping. The results could assist the system operator as an early detection of any instability to the power system. Index Terms- Graphical User Interface, Rotor Angle Stability, Transient Stability Assessment
