Funding entity Ministerio de Economía, Industria y Competitividad

Participated by Iberdrola Generación Nuclear

The aim of this project is the development of a detection system of open phase conditions in the start-up transformers of nuclear generating stations. The challenge comes from the fact that start-up transformers are at no load. The project involves simulation studies, development of small-scale laboratory protopytes and the implementation of a full scale prototype in Cofrentes nuclear generating station.

Project cofunded by the Ministerio de Economía, Industria y Competitividad, and by EDRF funds, under the thematic objective “Strengthening research, technological development and innovation”.

Research topics:
• *Steady-state: load flows, analysis of power system constraints, optimal load flows, voltage control ancilliary service,short-circuits, protections in transmission and ditribution networks
• *Electromagnetic transients: lightning and switching overvoltages in overhead and GIS substations, location of surge arresters
