Equipment Failure Detection Method of Substation Based on Tunnel Robot

Abstract

Indoor substation is critical facilities of power system, therefore inspection of substation equipment is crucial to ensure the security of power supply. Substation inspection robot can collection information through variety of sensors, then the appropriate approach is used to determine the operational status of the substation equipment. The state of most indoor substation device can be acquired by image collection, but this method is not applicable to all devices. A new method of monitoring the operational status of equipment in the substation is put forward in this paper. The audio signal is collected by dual channel collection equipment which is brought in the indoor intelligent robot. The angle information of collected signal is calculated according to signal procession theory. The operational status of equipment can be obtained easily by analyzing the angular information. Simulation result indicate the feasibility of the method. It combines audio signal procession and intelligent surveillance robot and the system is low cost and simple to realize with certain engineering value.
