Symmetrical and unsymmetrical fault analysis and applications in power systems

The static system of interconnected electric power transmission due to a lack of existing in the system generation, transmission and distribution commissioning of the system or any of the components due to rupture or removal due to the variability of the parameter values, the current power system analysis is planned. In the power system, it is necessary to select the switchgear that will be used and determine the operating characteristics of the protection relays that will provide protection and coordination to ensure safe and stable operation of the system. Interconnected system in Turkey within the scope of this study, belongs to the cross-section which is taken from the inner part of western Anatolia in the power system, program the power of the world computer aided graphics-based visual simulator for the power system are modeled in the program is a three-phase fault calculations symmetrical and non-symmetrical phase-to-ground, phase-to-phase and two-phase-ground fault calculations, each bar and lines belong to voltage, current, phase angle, active and reactive power and bus bar admittance values were calculated to determine the breaker locations to be included to protect the system and breaker strengths were calculated. Potential failure scenarios within the system in the simulator with the realization of the power flow of the power system and the impact on the magnitude of the malfunction, the system as a whole, the consideration of which will occur in line with the operational overload of the system by appearance of the front boundary conditions and ensuring continuity of energy, proactive and solution-oriented methods could contribute to the development of. It is aimed to analyze symmetrical and non-symmetrical failures and power flow, as well as to evaluate the types of failures by performing their applications, as well as to understand and emphasize the importance of the issue for power systems.
