Asset Management Model of SCADA Infrastructure of Power Control Centers based on Indicators

Abstract

This paper presents an asset management model for electric power control centers, adopting international standards and proposing management indicators based on realtime monitoring. This asset management model is based on the ISO 55001 standard; after validating the state-of-the-art it has been found that there is no proposal for the management of this type of assets, due to this, the proposed model adopts international standard processes such as: documentation, monitoring, change management, auditing and maintenance. For the implementation of the asset management system (AMS) of control centers, management indicators of the SCADA infrastructure assets are proposed, which is monitored in real time, and the data is stored in long-term historical records. The indicators were implemented in four control centers in Latin America. The calculation of the proposed indicators allows the system administrator to make decisions in the control center maintenance process based on the condition of the assets.
