Transient Stability Improvement of IEEE 9 Bus System Using Power World Simulator

Abstract

Abstract. The improvement of transient stability of power system was one of the most challenging research areas in power engineer.The main aim of this paper was transient stability analysis and improvement of IEEE 9 bus system. These studies were computed using POWER WORLD SIMULATOR. The IEEE 9 bus system was modelled in power world simulator and load flow studies were performed to determine pre-fault conditions in the system using Newton-Raphson method. The transient stability analysis was carried out using Runga method during three-phase balanced fault. For the improvement transient stability, the general methods adopted were fast acting exciters, FACT devices and addition of parallel transmission line. These techniques play an important role in improving the transient stability, increasing transmission capacity and damping low frequency oscillations.

Transient Stability Assessment of IEEE 9-Bus System Integrated Wind Farm

“…The optimal method showed better results than the normal load flow method, and the fuel cost of the system was minimized. The Flexible AC Transmission Systems and adding a transmission line were used to improve the transient stability of the 9-Bus system during the fault [12]. The results indicated the effectiveness of these techniques to broaden the stability limit and increase the capacity of transmission lines.…”

“…A 9-bus system is a simple model used for stability analysis; it requires a small amount of data. Several articles and research works have discussed the normal operating conditions and transient stability study of the 9-Bus system [11][12][13]30,31]. In our research, the 9-bus modified system is considered and simulated through MATLAB R2019b.…”

“…The parameters of transmission lines come from the literature [30,31]. The system is equipped with three generators rated 16.5 kV/247.5 MVA, 18 kV/192 MVA, and 13.8 kV/128 MVA [12,30,31]. The system contains three transformers to step up the voltage of each generator to 230 kV.…”

“…The system contains three transformers to step up the voltage of each generator to 230 kV. It comprises three loads connected at bus 5, bus 6, and bus 8 [12,30,31]. The system has a fundamental frequency of 60 Hz.…”

Synchronous machine analysis and modelling in LabVIEW: An educational tool for transient stability studies

“…as it can be found in Kaur and Kumar. 10 Despite this plethora, the aforementioned tools present a low "learning to using" ratio, which is a drawback for short (semester type) studies and also the corresponding high purchasing and maintenance cost is almost prohibited for every day laboratory use.…”
