Introduction
Coal mine intelligent power supply system is an important part of intelligent mine construction. Coal mine intelligent power supply system can improve the reliability of coal mine power supply
It is of great significance to ensure the safety, efficiency and green production of coal mines. In order to standardize the construction of intelligent power supply systems in coal mines, in accordance with the "unified planning, unified
This document is specially formulated based on the principle of "standard and unified construction".
Based on the characteristics of the intelligent power supply system and the actual situation of the coal mine power supply system, this document discusses the technical principles and technical principles of the coal mine intelligent power supply system.
The system structure, substation intelligent equipment and functional requirements, and centralized control center functional requirements were standardized.
This document is a technical guidance document for the construction of intelligent power supply system in coal mines. For actual project implementation, it is based on referring to this document.
On the other hand, relevant design specifications will be formulated separately.
