Method for detecting state of ground wire in substation

Abstract

The invention discloses a method for detecting the state of a ground wire in a substation. A ground wire controller is installed on a ground connection wire; a ground connection pile coding and a ground wire cabinet coding are respectively installed on a ground connection pile and a ground wire cabinet; when the ground connection wire is connected to the ground connection pile, the ground wire controller can detect the ground connection pile coding of the ground connection pile; when the ground connection wire is placed in the ground wire cabinet, the ground wire controller can detect the ground wire cabinet coding of the ground wire cabinet; when the ground connection wire is for standby, the ground wire controller can not detect the ground connection pile coding and the ground wire cabinet coding, transmits the coding information to a base station through a wireless network, forwards the coding information to a host through the base station, judges the state of the ground wire by thehost, and can conveniently realize complete detection of three states, such as assembling and connection, standby and storage of the ground connection wire.

Description

technical field [0001] The invention relates to a method for real-time detection of the use state of a substation ground wire. Background technique [0002] The upgrading and transformation of substation equipment has enabled the monitoring system of most substations to have the ability to detect the status of switches, switches and grounding switches. However, due to the special use of the grounding wire, it is difficult for the monitoring system to detect its status. Many monitoring systems obtain the status of the grounding wire through communication with the anti-malfunction operating system. There are two main ways for the anti-malfunction operating system to detect the status of the grounding wire: one One is the online type, and the other is the key type. [0003] The online detection method is: laying a measurement and control network between the anti-malfunction host and each equipment lock, and detecting the connection of the ground wire through the ground stake l...

AI Technical Summary

Problems solved by technology

Both have the problem of incomplete detection, that is, only the connection state of the grounding wire can be detected, and there is nothing to do about the standby state and storage state
