Program development for condition evaluation of gas-insulated switchgear
Abstract:
This thesis presents condition assessment of assets in gas-insulated substation for maintenance management in industrial area. The components of GIS substation such as GIS compartment, circuit breaker, disconnecting switch, earthing switch, high speed earthing switch, current transformer, voltage transformer and local control panel are evaluated. The 28 bays of a 115 kV GIS substation in the industrial area are evaluated as an example. The weighting and scoring method is applied for the condition assessment to obtain the health indices of these components. Subsequently, these known component health indices are used to calculate the overall health index of GIS substation. This developed method is further developed by using the dynamic programming to obtain a web application assessment program. This software can facilitate previous complex and costly preventive maintenance to condition based maintenance. The results show the health index of components, health index of bay and health index of substation in form of percentage. The known health index of substation and its component is useful information to manage the maintenance activity with the associated cost and to plan the effective maintenance scheduling for GIS substation.
