| Abstract: | This paper presents a scheme that fuzzy set theory is applied in transformer protections. which can discriminate magnetic inrush current by using fuzzy logic and fuzzy pattern recognition. The digital simulation shows that the scheme can diminish a lot of defects of transformer protection and improve the performance. The fuzzy set theory makes a perfect coordination of relay's speed and selectivity. |
