Transient Stability Analysis of 11 Bus Systems

Abstract

Stability of the system is the important parameter for the stable, profitable and proper operation of the power system. The main aim of this research project is to implement the transient stability of the 11 bus power system in power word simulator. Two generators are modeled with different MW ratings. Our system is interconnected system of 11 Buses. The fault is created on different buses and analyzed by bus admittance matrix. Furthermore, the modelling of this system is done on power word simulator. The designing of the electric power system is mandatory to study the small and transient disturbance. The rotor angle variation and bus faults at different buses are studied and also studied its impact on the load. When there is fault or any kind of disturbance on the system, the rotor angle of the generator changes and its frequency also changes. These rotor angle variations can be simulated in the power word simulator. in this research work, it is clearly observed in the simulated graphs that when there is disturbance or fault in the system then the system cannot come back to stability position. As the fault or disturbance is removed then the power system comes to stability. The system that is proposed is universal and generalized system than any other power system. This system has proposed in the aspect that it can be applicable to any power network irrespective of the power generation that how fault affects the stability and rotor angle, how bus admittance matrix changes with the instability of the system. in this system it can be easily analyzed that how voltages vary on different phases when fault occurs on the system.
