Application of Wavelet Packet and Fuzzy Algorithm in Power System Short Circuit Fault Classification

Table 4

Comparison of methods.

SN	Algorithm	Characteristics
1	Wavelet packet +	The membership function and fuzzy rules should be set correctly. Without sample training, high calculation efficiency, and high accuracy.
	Fuzzy logic
2	DWT + SVM	Fault location error is slightly larger due to training samples, a large amount of calculation, and long computing time.
3	ANN	Need learning training, require many learning samples, and long computing time.
4	GA-GNN	Need learning training, poor scalability, slow convergence, long computing time.
