This paper presents the safety assessment of a grounding system at an indoor-type 161/23.9-kV substation based on voltage-dependent body resistance. For a grounding system to be safe, the maximum actual touch and step voltages should not exceed postulated safety criteria. Thus, the safety assessment of a grounding system is referred to a procedure by which the actual maximum touch and step voltages...
This paper presents an extended complex Kalman filter artificial neural network for bad-data detection in a power system. The proposed method not only can improve one-by-one detection using the traditional approach as well as enhance its performances. It uses complex-type state variables as the link weighting to largely reduce nodes number and converging speed. In other words, it not only can largely...
