This work presents a new approach to optimize overcurrent relay coordination in power distribution systems by using a genetic algorithm, involving transformer protection. An effective objective function with constraints is adopted to solve the relay coordination problem, considering not only the time setting but also the current setting multiplier. There are various types of curves such as Very Inverse...
In this paper a modified genetic algorithm is used to perform the IDMT overcurrent relay coordination applied in an industrial plant radial power distribution system for quickly getting the result of the best coordination comparing with the computer-aided software of traditional method. The result shows that it is fast and adoptable compared to the traditional method by verifying with an existing...
