1. Background
Iberdrola is a private electrical utility in Spain, created by the merger of Hidroelectrica
Esptiola and Iberduero in 1991. Iberdrola currently supplies energy to 7.9 million customers
(38 percent of the Spanish market). The inventory distribution file was begun in the 1970s,
and in the 1980s, the first AM/FM systems (based on Intergraph products) were installed in
all the distribution territories.
Although we continue to collect data and develop applications, we are not obtaining all of the
expected benefits. In January of 1997, the Vice President of Distribution recommended both
an updated cost-benefit analysis, developed by internal users and external experts, and a new
plan to optimize the software applications supported in the SIGRID system (Distribution
Facilities Information System, inventory, and cartography).
2. Sigrid Functionalities
2.1 Cartography and inventory
The cartography facilities may be viewed as follows:
- In a simplified form.
- As orthogonal diagrams (to be integrated with SCADA and Computer Aided
Distribution Operation Systems).
- As detailed U.T.M drawings of the network with reference information (cataster,
environmental restrictions, etc.)
The alphanumeric inventory includes all the items and attributes of the network equipment.
2.2 Applications
Existing applications support maintenance, design, distribution automation, service
restoration, planning, and new engineering requests.
