ENERGY METERING AND POWER QUALITY SYSTEM

ESB Networks has chosen Premium Power Ltd. (www.premiumpower.ie) as the supplier, integrator and supporter of a nationwide combined energy revenue and power quality monitoring system.

As part of a major €2 billion refurbishment program of Ireland’s national electricity network, ESB is upgrading the country’s electricity distribution infrastructure with an enterprise energy management system based on the ION® system using a network of intelligent energy meters and software to help staff automatically track and profile electricity transactions at more than 150 metering points around the country. In addition to simplifying bulk-metering tasks, the system monitors a range of power quality factors to help improve the overall efficiency and stability of the grid.

According to the Meter Asset Manager for ESB Networks, the ION system is expected to help safeguard Ireland’s national electricity distribution system by identifying potentially disruptive conditions before they can cause problems.

NATIONWIDE SYSTEM

Initially, ESB is fitting each substation and renewable energy connection with ION 7600 and ION 7650 energy meters to monitor the cost, quality and reliability of the electricity delivered. The meters report this information to the ION server located at ESB head office and the server logs the system data. While this asset management information is delivered directly to the ION Enterprise energy management software, profile data is also sent to a separate centrally located revenue-logging server running a third-party data-collection application.

The system monitors power quality characteristics such as harmonics and voltage fluctuations. Each meter also monitors compliance with the European EN 50160 voltage standard.
