Artificial immune systems applied to voltage disturbance diagnosis in distribution electrical systems

This paper presents a method to voltage disturbance diagnosis in distribution electrical systems. This issue uses three phase voltage measures which are obtained at the substations to realize the system monitoring. The principal application is to aid the operation during faults, as well as to supervise the protection system. To evaluate the performance of the proposed method simulations were executed at EMTP software for two distribution systems containing 84 and 134 busses, respectively.
