Model Choice and Design Idea of Electric ‘Five Protection’ Device

Abstract

Abstract: Based on analysis of the applicable scope of various electric ‘five protection’ device and the equipment features of Yangzhou Second Power Plant, the on-line micro-computer ‘five protection’ scheme was selected. According to the principle of complete function and convenient for use, the system design idea was expounded. The system structure, anti-misoperation lockout logic and system main function were introduced briefly.

Key words: electric ‘five protection’, malfunction protecting device, anti-misoperation, system, design idea
