Problems solved by technology

Since there is no GIS bus current data in the EMS system (Energy Management System), this brings great inconvenience to the GIS test, especially for the GIS bus equipment, when the infrared temperature measurement is performed on it, due to the lack of load current data As a reference, the accuracy of its temperature measurement is low

Abstract

The invention provides a method for on-line monitoring of a load current of a GIS bus of a substation. The method comprises the steps that a distribution diagram of GIS device intervals is drawn according to site layout information of a GIS of the substation, and the GIS bus is sectioned according to the distribution diagram and the actual physical information of the substation; the load current of each line and the quantity of states of switches and disconnecting links of the substation are obtained from an EMS system; the load current of each subsection of the GIS bus is calculated according to the Kirchhoff law, the load currents and the quantity of states; on-line monitoring is conducted on the GIS bus according to the load current of each subsection of the GIS bus of the substation. According to the technical scheme, real-time on-line monitoring of the load current of each subsection of the GIS bus of the substation is achieved, more direct state parameters in the GIS operation process are obtained, more reliable data reference is provided for infrared detection and GIS tests, stable operation of the GIS device is guaranteed, and the reliability of power supply of the power system is improved.

Description

Technical field [0001] The invention relates to the technical field of electric power engineering, in particular to an online monitoring method for the load current of a GIS bus bar in a substation. Background technique [0002] SF6 gas insulated fully enclosed combined electrical appliances (GIS) are widely used by power users due to a series of advantages such as small footprint and high stability. However, with the passage of operating time and increasing load demand, the reliability of GIS equipment operation has attracted the attention of power users, and its maintenance mode urgently needs to change from regular maintenance to state maintenance. [0003] Due to the limitation of the enclosed structure of GIS equipment, partial discharge detection methods are currently mainly used to monitor GIS operating conditions online. Partial discharge is mainly used to determine whether there is internal partial discharge through UHF wireless reception or coupling ground signals. Probl...
