Design and Function Realization of Intelligent Substation Fault Identification and Isolation Device
To further enhance the stability of the coal mine power supply system,ensure the safety and reliability of coal mine production,based on the analysis of the basic structure of intelligent substations and the development trend of future intelligent substations,the characteristics of the power supply system are studied.Subsequently,based on regional centralized control technology,identification and isolation devices for coal mine transient faults and abnormal operating states were designed,and identification methods for faults such as overload,undervoltage,overvoltage,and short circuit were proposed,as well as algorithms for isolating all faults.
