| Abstract: | The power supply interlocking device is an important guarantee for the safe operation of the power supply system. How to improve the reliability of the device is of great significance for ensuring the safety and stability of the power supply network and improving the vitality of the power supply system. The article introduces the software and hardware components and implementation methods of the power supply interlocking device based on Siemens S7-300 software redundant system. Based on the understanding of the working principle of the software redundant system, the data synchronization time and failover time of the active and standby systems are analyzed. The article also uses the Markov method to analyze the system reliability of the redundant system, and concludes that the soft redundancy technology has a greater effect on improving the reliability of the power supply interlocking device. |
