Determination of Relay Opening Current Information and Coordination of Distribution Network of Sakarya Province, Yazlık Region

Electricity is delivered to end users through generation, transmission, and distribution phases. The most important issues during energy journey provide selective, rapid, safe protection ensure continuity. In this context, when the operating conditions defined in systems are exceeded, an effective system coordination required that as few consumers possible affected by outage reliably isolate fault. If short circuit not separate from network quickly after a occurs, equipment electrical devices may be damaged because of overcurrent occurs. study, relay at 34.5 kV voltage level Sakarya Province, Serdivan District, Yazlık region made MATLAB/Simulink used modeling system. All data inspected embedded file then optimum provided on settings performing power flow analysis calculations.
