Research on Optimization of BIT Design Scheme for Digital NBC Protection System

[摘要] BIT technology is an important means to detect, locate and isolate faults of system and equipment. In this paper, the digital NBC protection system is taken as the research object, and the on-line state detection method based on BIT technology is studied. The system structure division and analysis of typical fault mode have been done. The design flow of online state monitoring based on BIT technology is presented. A weighted cost indicator function is constructed. This paper also presents a selection method for selecting the optimal test set based on improved specially-stepwise optimal selection method for digital NBC protection system. From the theoretical point of view, the system typical fault mode is extracted and the BIT design objective is set, and finally, the optimal BIT design scheme is determined.
