Problems solved by technology

[0003] In addition, because the transient circulating current generated in GIS has high-frequency and ultra-high-frequency components, and the layout of GIS cannot be consistent with the distance from the ground current injection point, it will cause the TGPR (Transient Grounding Potential Rise) effect of GIS, which may Electromagnetic interference will be generated to the monitoring and measuring equipment on the secondary side, causing system malfunction and becoming a huge hidden danger to the normal and stable operation of the power system

Abstract

The invention discloses a GIS (Gas Insulated Switchgear) shell circulating current and transient grounding potential rise (TGPR) modeling and analysis method based on a PEEC method. On the basis of the circulating current and transient grounding potential rise generation mechanism in the GIS system, the PEEC method is adopted to build a GIB busbar and shell model, an equivalent model is further built for simulation, the relation curve between amplitude of GIS inter-phase circulating current and grounding grid circulating current and a grounding point is obtained, and according to the relationcurve, influence factors for the shell circulating current and the TGPR are determined. Power grid protection and control adjustment are facilitated.

Description

technical field [0001] The invention relates to a method for modeling and analyzing GIS shell circulation and transient ground potential rise based on the PEEC method. Background technique [0002] In recent years, Gas Insulated Switchgear (GIS) has become an indispensable part of the power system due to its remarkable advantages such as compact structure, small size, small footprint, reliable operation, light maintenance tasks and less environmental pollution. . However, the distance between the components of the GIS system is relatively close, and the electromagnetic coupling between the components is strong. When the disconnector, circuit breaker, etc. are opened and closed, there will be a fast transient process in the GIS. The transient wave generated in GIS has the characteristics of short delay and high frequency. The rise time of these transient waves is nanoseconds, and the frequency can reach hundreds of megahertz. Through electromagnetic induction, it appears as ...
