Network Resource Manager (NRM) – Standard Applications for Utilities

Smallworld NRM

Smallworld NRM provides a sophisticated product suite with standard data and process models for Smallworld GIS that are being used by more than 300 utility customers worldwide. It supports a wide range of technical business processes such as data update, engineering design, network operation and Asset Management at all enterprise levels.

GE Energy and Mettenmeier have successfully introduced the NRM product suite to the international market as commercial-off-the-shelf (COTS) applications, giving Smallworld users the chance to break the cost-cycle and leading to easy and thus cheap maintenance.

The high market acceptance rate of the Network Resource Managers is also mirrored in the numerous supplementary products that exist today. These include network calculation, operation, analysis, periodic network integrity checking, network control and interfaces e.g. with SAP.

Support of Regulations

The development of the NRMs is based on common industry regulations and norms such as VDE-AR-N 4201 and GW 120. These are supported by the NRMs. In addition, the NRM data models conform with the specifications of associations such as VDEW, AGFW and DWA as well as standards like CIM or DIN.

Current requirements of the regulatory authorities within the meaning of § 3 No. 27 EnWG and the industry associations are also taken into account in the further development in order to provide the best possible support for regulatory management. The modules Grid Analysis and Grid Statistics, contained in the standard NRMs, collect and process GIS-relevant information such as line lengths, connection rates or grid complexity. The standard module Outage Statistics provides the functions required for the reporting of supply disruptions.
