摘要
Abstract
The deficiency of traditional relay protection is analyzed , and the concept of flexible operation features of relay protection is proposed . That is , operation features are determined with a variety of criteria according to the fault characteristics of protection objects . Compared with the operation features using a single criterion for relay protection , flexible operation features are suitable for cases of indistinct fault characteristics . The application occasions of the protection flexible operation features are described , including transformer excitation inrush current identification , distance protection oscillation block open conditions , the rapidity and accuracy of high resistance grounding fault , and so on . Finally , the application prospects of the relay protection flexible operation features are previewed .关键词
