Symmetry feature recognition of maintenance information in regional power grid dispatching system

For the promotion of regional power grid dispatching system maintenance information symmetry feature recognition efficiency and accuracy,the characteristics of regional power grid dispatching system maintenance information is extracted,and then the distribution of characteristic data is analyzed by the fuzzy c-means algorithm.On this basis,the waveform of the symmetry fault characteristic of the maintenance information is obtained,and the recognition of the symmetry characteristic of the maintenance information in the regional power grid dispatching system is realized according to the U cos θ waveform characteristic recognition result.The experimental results show that this method can effectively realize the recognition of symmetry characteristics of maintenance information in the case of symmetry faults in different oscillation periods,and the recognition results are basically close to the actual situation,which proves that the recognition effect of this method is significant.At the same time,the recognition efficiency and accuracy of this method are also high,which proves that this method has superior recognition performance.
