e-terraassetcare 3.0 A strategic move for your electrical Assets

Develop smarter maintenance and Asset replacement strategies

Under the conflicting pressures of reducing costs while maintaining or even increasing quality of service, your strategy for managing your grid assets is facing new challenges. How to move from today’s approaches of “run to failure” or “periodic maintenance”? How to develop smarter strategies that are less costly, less disruptive for grid operations, and actually support your business objectives ?

Get Data for decisions

Collecting the right data is the first step to effectively improve your asset-related decisions. As an example, your regulators will require concrete facts and data to justify your investment plan, in relation with your performance objectives or regulation compliance criteria.

Before creating more, you should also make an optimum use of your existing data. How to take advantage of all operation history data from your Energy Management System (EMS). or Distribution Management System (DMS)? How to turn data from your condition monitoring IEDs into actionable information and sound business dashboards?

Bridge the silos

In the context of ageing infrastructure, securely operating assets and maintaining adequate contingency planning is equally critical. For this, you need to bridge effectively the maintenance & asset domain with the grid operation domain in charge of delivering the quality of service to your customers. Often operated in silos, these two domains must find ways to collaborate, benefit from each other expertise, and align their business processes for an increased efficiency, as promoted in the Smart Grid Maturity Model.

e-terraassetcare 3.0 A Strategic Move for Your Electrical AssetsThe new e-terra3.0 is the most advanced, fully integrated, smart grid-ready suite of products for the 21st Century Grid. e-terra3.0 is developed by the world’s leader of energy management and electricity market systems and THE only player in the industry who offers a full solution from market-to-meter for the new grid. Your Grid. Reinvented.

By any measure, the changes that occurred in the electric utility industry in the last 20 years are anything but simple. They introduced incredibly complex problems to solve, a lot more players and technology than ever before. Yet, in this world of drastic changes, the core business remains: the utilities’ mandate of building and maintaining electrical networks, as a cost effective and reliable system, operated efficiently.

Managing electrical Assets: the Business Problem

Moving up the strategic intent

With e-terraassetcare 3.0, Alstom Grid provides the tool to effectively support advanced strategies in the field of asset maintenance, asset replacement, and risk-aware grid operation. These strategies can move from time-based, to usage-based, to condition-based and to reliability-based by considering the criticality index of each piece of equipment.

Adding expert knowledge and predictive models into business analytics

Smart condition monitoring devices can be integrated via standard protocols such as IEC 104, DNP3, or OPC to bring real time condition data in the picture. Alstom Grid products such as MS3000 for Transformers, CBwatch and GISwatch for Gas Insulated Substations, PDwatch for Partial Discharge analysis, can bring their equipment expertise and diagnostics capabilities.

e-terraassetcare 3.0 provides interfaces to consolidate all asset related data, coming from manual records, inspection reports, and also usage data from systems such as the EMS.

All these data are combined to produce advanced, synthetic indexes such as the Asset Health Index AHI representing the effective age of each piece of equipment.

By comparing actual equipment records against performance datasheets of the equipment manufacturer, you can detect unexpected degradation of the equipment over time.

Presented in comprehensive dashboards, this information can be used to issue alerts for maintenance actions and even trigger work orders in the Enterprise Asset Management System (EAM).

In addition to the diagnostics and detection of anomalies, you can build an asset evolution forecast based on past trends, history of operations, actual service requirements and equipment conditions, combined with typical ageing curves from the manufacturers.

This can be used to define an optimum maintenance schedule, no longer based on time only, but also taking into account the actual equipment conditions and probable evolution, thus optimizing maintenance expenses.

Creating overall situation awareness

The fleet analysis view also brings a global approach to analyzing and correcting systematic equipment misbehaviors. Those performance summaries can be used as Key Performance Indicators and published via ad-hoc reports to all interested parties within the utility organization.

In a subsequent step, the criticality index of each piece of equipment can be added to combine the health information with the business impact of a potential failure of this piece of equipment, and therefore provide a risk-aware view of the situation.

This approach can provide early warning signals and avoid potential harmful situation, such as sudden failure of a piece of equipment with immediate impact on the grid operation and emergency outages. This leaves more time to the grid operator to find alternate operation scheme, such as equipment de-rating, generation re-dispatch or load transfer for instance.

The Asset Health Index information can also be made available to your EMS, and used as a measurement of the risk attached to each piece of equipment. This can be applied to the Contingency Analysis application, so that contingency planning can now take into account the actual state of the devices, and build a global risk assessment at grid level.

Integrating domains

User Interface navigation is provided between the asset electrical view of e-terraassetcare 3.0, the grid operation view of the EMS (such as Alstom Grid’s e-terraplatform), and the maintenance process view from the Enterprise Asset Management EAM. Any given asset can be viewed seamlessly in its history and asset health context, in its operational role in the EMS, or in the progress of its on-going maintenance actions in the EAM.

All interfaces are built with modern interoperability techniques, using web services and IEC standards wherever possible. MRIDs from IEC 61970 CIM standards are used to uniquely identify devices, compliance to IEC 61868 is built as the standard matures, as evidenced by the interoperability test passed in March 2011. This provides e-terraassetcare 3.0 with vendor neutral solutions, allowing integration with any EMS or EAM.

What’s more, data can be made available at your fingertips using Alstom Grid Viewer on iPad.
