The objective of power system protection is to isolate a faulty section of electrical power system from rest of the live system so that the rest portion can function satisfactorily without any severe damage due to fault current. 10.

The conventional method of power system protection and control (Principle) Optimal reactive power dispatch (ORPD) is a complex and non-linear problem, and is one of the sub-problems of optimal power flow (OPF) in a power system. These sections are protected by protective relaying systems comprising of instrument transformers (ITs), protective relays, circuit breakers (CBs) and communication equipment. (Overcurrent Protection) A protection relay is a device that responds to abnormal conditions in an electrical power system to operate a circuit-breaker to disconnect the faulty section of the system with the minimum interruption of supply. Modern power systems are being operated closer to their stability margins because of deregulation, competition, and problem of securing capital outlays expansion of existing power system. endobj Dr. Ibrahim El-Amin; 2 Protective Device Coordination 3 Definition.
