Testing of local control cabinet in gas insulated switchgear using design of simulation kit - Revista

Abstract

In order to keep generation and distribution of power at high priority, two switchgear playing a key role i) Air insulated Substation/Switchgear (AIS) ii) Gas Insulated Substation/Switchgear (GIS). Nowadays, the GIS innovation began with the view of broad essential research and from that point forward the administration encounter together with creative advancement work has presented this system to a sheltered and natural good, a most dependable and accessible component of the power supply. Controllers always play a significant role in the power sector. GIS has low-Local Control Cabinet (LCC) cost and can be utilized for indoor and open-air applications. The local control cabinet is controlling part in Gas Insulated Switchgear. Its task is to follow the logic and interlocks that are set accordingly. The Problem came across while testing LCC panel is studied in this paper and solution to this is found out. In this paper, a test kit for LCC is proposed which will work as a dummy GIS bay. The contact status is found out whether NO or NC by studying connection drawings. This status fed to the relays in the kit through PLC-HMI programming and testing will be done. The proposed test simulation kit allows conducting a full functional assessment of LCC panel, panel wiring, interlock wiring, component functioning etc. © 2019 IEEE.
