Bus Short-Circuit Fault Detection and Repair Technology for Improving Inverter System Reliability

The advancement of modern power electronics technology has elevated the importance of inverter systems within power applications, where their reliability is pivotal to the overall stability of power systems. Among the primary challenges faced are bus short-circuit faults, which can arise from external natural factors, internal aging, and installation issues. These faults often result in significant equipment damage and economic losses. This paper explores the synergistic application of fault detection technologies, including current, voltage, and temperature monitoring, alongside intelligent algorithms, to enhance detection accuracy and response speed. In the realm of fault repair, techniques such as automatic reclosing, sectional protection, online repair, and preventive maintenance have proven effective in minimizing power outage duration. Looking ahead, fault detection and repair technologies are anticipated to progress towards greater intelligence, automation, integration, and environmental sustainability. This evolution will likely involve the use of big data and artificial intelligence for intelligent prediction and diagnosis, as well as the adoption of green materials to bolster system reliability and sustainability. This paper underscores the critical importance of developing a comprehensive fault detection and repair system. Such a system is essential for ensuring the stable operation of power systems and for laying a robust foundation for future technological advancements.
