29 Actual Trends in Development of Power System Protection and Automation Input inputmf rules outputmf output Fig. 5w RR ≤ cc if u d Notice that for Equation (5) cL specifies the “saturation point” and wL specifies the slope of the nonunity and nonzero part of μL as shown in Figure (2) Similarly, for μR. For μC notice that c is the centre of the triangle and w is the base-width. cL, cR, c, wL, wR, and w are the parameters set. As the values of these parameters change, the triangular function varies accordingly, thus exhibiting various forms of membership functions for fuzzy set A.

The protection algorithms are simple since Rogowski Coils do not saturate. In addition, multiple slopes are not required. Transformer inrush currents are determined using a current waveform recognition algorithm. Protection settings can be at a lower current threshold compared to conventional solutions based on CTs. The load tap changer position is also used by the relay to adaptively adjust the transformer ratio allowing the set threshold to be further reduced. 4. Busbar Protection Rogowski Coils can provide reliable protection for all types of bus bars and at any fault current level.

There are 444 training data. The input data to the ANFIS of the location unit are as same as those of the ANFIS of the classification unit without the zero sequence current.
