Abstract—This study, discuss how to raise power transferred capacity, to improve system Stability. A principle object of the study was to determine maximum allowable power which Resha plant can generate with the condition keeping stability even in occurrence of transient disturbance and then study several solutions improve the stability of plant generator. Keywords—Stability, generation, energy sector, electricity. I. INTRODUCTION LECTRICAL systems are designed to operate in stable conditions. At this point, the system must satisfactorily function and remain stable always, especially when a severe disturbance takes place into the system. In Jordan natural gas is produced from the Al-Resha field which is in the gas production in the eastern part of Jordan, gas production started in 1988. Energy production by local gas in 2011 is (574 GWH) electricity natural gas Consumption in 2011 is 848.5 thousand ton of oil equivalent Resha power plant, had trouble duo to transient instability the stable operation would become of greater importance, when generated power Reach certain limits[1-3]. This study focuses on Resha generating plant as a study case it is located in East Jordan and contributes of 15% of generated energy in the kingdom. Therefore, the reliable performance is very important, especially, if a Transient disturbance impact the plants. As the loads on generators increase and Due to the high reactance on transmission lines, it is more likely to lose Synchronism among plant's generator and the generators become out of Service. Traditionally various methods have been used to improve transient stability Such as adding shunt reactor, building up new transmission line, in these techniques the Final targets have been briefly; approve system stability and increase power transferred [4-5].

TRANSIENT STABILITY Transient stability concerns with the matter of maintaining synchronism Between all generators when the power system is suddenly subjected to severe Disturbance such as fault or short circuits caused by lightning strikes, the sudden Removed from the transmission system of a generator and/or a line, and any Severe shock to the system due to a switching operation. Because of the severity and suddenness of the disturbance, the analysis of Transient stability is focused on the first few seconds, or even the first few Cycles, following the fault occurrence or switching operation [6-8]. First swing analysis is another name that is applied to transient stability Studies, since during the brief period following a severe disturbance the generator undergoes its first transient overshoot, or swing. If the generator(s) can get through it without losing synchronism, it is said to be transient stable. On the other hand, if the generator(s) loses its synchronism and cannot get through the first swing, it is said to be transient unstable. Many factors affect the transient stability of a generator in a practicable power system. From the small system analyzed above, the following factors can be identified [9-10]. 1. The post-disturbance system reactance as seen from the generator. The weaker the post-disturbance system, the lower the Pmax will be. 2. The duration of the fault-clearing time. The longer the fault is applied, the longer the rotor will be accelerated and the more kinetic energy will be gained. The more energy that is gained during acceleration, the more difficult it is to dissipate it during deceleration. 3. The inertia of the generator. The higher the inertia, the slower the rate of change of angle and the lesser the kinetic energy gained during the fault. 4. The generator internal voltage (determined by excitation system) and infinite bus voltage (system voltage). The lower these voltages, the lower the Pmax will be. 5. The generator loading before the disturbance. The higher the loading, the closer the unit will be to Pmax, which means that during acceleration, it is more likely to become unstable. 6. The generator internal reactance. The lower the reactance, the higher the peak power and the lower the initial rotor angle.9 7. The generator output during the fault. This is a function of faults Location and type of fault. Decreasing the Risk of Transient Disturbance on the Resha Generation Plant Mahmud S.
