NB/T 11115-2023Technical guidelines for smart power system in coal mine (English PDF)

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

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.

1 Scope

This document defines relevant terms and definitions of coal mine intelligent power supply systems, and clarifies the technologies for the construction and transformation of coal mine intelligent power supply systems.

The principles and system structure stipulate the requirements for the equipment functions and system functions of the coal mine intelligent power supply system.

This document is applicable to the intelligent power supply of coal mines composed of surface and underground substations in underground coal mines with voltage levels of 110kV and below. system.
