Description: This paper proposes a fault location method employing wavelet fuzzy neural network to use post-fault transient and steady-state measurements.
When single line to ground fault (SLG) occurs in the distribution lines of an industrial system, the transient feature is distinct
and the high frequency components in the transients can be employed to reveal fault characteristics. In this paper, wavelet transform is
applied to extract fault characteristics from the fault signals. Fuzzy theory and neural network are employed to fuzzify the extracted
information. Wavelet is then integrated with fuzzy neural network to form the wavelet fuzzy neural network (WFNN). The WFNN
is most suitable for post-fault transient and steady-state signal analysis in industrial distribution power system. Analysis and simulation
results illustrate that the theory and algorithm of the WFNN proposed in this paper are efficient in fault location. The WFNN can be
widely applied in fault analysis of power system.-Application of wavelet fuzzy neural network in locating single line
to ground fault (SLG) in distribution lines Platform: |

power load demand varies randomly, in the case of any small
sudden load change in any of the areas, both area frequency and
tie-line power flow interchange also vary. The main goals of Load
Frequency Control (LFC) are, to hold the frequency and the
desired power output in the interconnected power system at the
scheduled values and to control the change in the tie-line power
flow between control areas. The purpose of this paper is to
present basically an application of Fuzzy Logic Controller (FLC) Platform: |
