Increasing the critical clearing time to enhancement the transient constancy by using braking element.

The constancy of the power system maintains equilibrium in normal conditions. If the system is subjected to disturbance, it must return to a stable state. Depending on the components and operating conditions of the network, the instability takes many forms. A resistance was added to the faulty bus, and for the purpose of reinforcement, its value was increased. Still, a decrease in the angle value was observed, and this situation is considered undesirable. Therefore, the braking elements technique was used for the purpose of improving the transient stability of the system. The elements were mathematically represented and modeled for the purposes of transient constancy calculations using Euler's developed iterative method for numerical integration. The time has been increased without adding other operations to improve stability and obtain the critical clearance time. One system, which consists of five generalities, including two for obstetrics, was selected for the purpose of conducting the study. The results confirmed the effectiveness of this method in improving the network stability of the system and damping fluctuations. [ABSTRACT FROM AUTHOR]
