Unfavorable Effect KP on Power System and Artificial Intelligent Alarm System for It

For space weather phenomenon that is searched always, in the paper, solar activity effects on power system are considered. According research, solar plasma can have unfavorable effect on power system. Such as saturation of the transformer core, extra harmonic that can switch out of service such Quebec blackout of March 13, 1989 witch left the whole province without power for over 9 hours. For reason, in this paper is predicated plasma with neural network methods(MLP, RBF, ANFIS and LOLIMOT). The best result was for LOLIMOT with correlation factor of 0.7843 and normalize error = 0,8752 and observed values. The rate of correct, missed and false detections for various warning messages are calculated and reported. This method can work similar an alarm intelligent system for power system.
