The Real Time Supervisory Control System for Coal Mine Substation Underground Based on CAN Bus;

Analysis on present construction situations of underground substation;

Operational problems for large underground substations and relevant countermeasures;

Application of uplift piles with hole expansion end to anti-floating design for underground substations;

Daliuta Coal Mine is leading the colliery complete automation system,and was the first one to operate the underground substation without local operator,and the "thr.

In order to improve reliability and real-time of detection data and control data of underground substation,the paper proposed a design scheme of remote monitoring and control system of underground substation based on CAN bus and Ethernet.

This paper expounds the design scheme of underground sub-station communication in coal mine based on CAN bus that consists of SJA1000 and PC82C250, and gives the hardware structure and software design of this communication node.

The purpose,input conditions and main technical and economical indices of typical design for 220 kV and 110 kV substations are presented,according to the form of the power distribution unit the typical design is divided into three basic schemes for outdoor,indoor and semi-subterranean substation respectively.

Because the 500 kV underground substation has such characters as deep underground,and difficult for fire fighting and smoke ventilation,etc.
