Abstract

This paper explores high-voltage switching equipment secondary circuit technology based on domain-based control, aimed at overcoming the technical challenges present in current traditional and intelligent substations. Traditional high-voltage switch secondary control circuits employ a multitude of discrete electromagnetic components, which not only increases system complexity but also reduces reliability and complicates maintenance due to the numerous connecting wires involved. Moreover, the variety of product specifications for high-voltage switches, lacking standardization, adds to the design and operational difficulties. By integrating a domain-based control system, a segmented control network system based on circuit breaker control domains and isolator control domains is proposed. This research demonstrates how reducing the use of discrete components and wiring can enhance the overall reliability and rapid-protective response of the system. Experimental results indicate that domain-based control not only optimizes control strategies and response speeds but also significantly reduces maintenance costs and complexity through standardized design. The findings of this study hold significant theoretical and practical relevance for the design and operation of modernized substations.
