SciGrid
SciGrid is a project started in 2014 and running for three years to develop an open and free model of the European transmission network. It is carried out by NEXT ENERGY - EWE Research Centre for Energy Technology, an independent non-profit institute at the University of Oldenburg, Germany, and funded by the German Ministry of Education.
Bialek European Model
The 2nd version of the Bialek European Model is downloadable as an Excel file and in the format of the proprietary modelling software PowerWorld. The model covers voltages from 110 kV (a single line in the Balkans) up to 380 kV.
The 1st version was released in 2002-2004 and is no longer available (see Archive mirror). The 1st version did not contain the Balkans region.
The methodology and validation for the 1st version of the model can be found in the paper Approximate model of European interconnected system as a benchmark system to study effects of cross-border trades by Zhou and Bialek, 2005.

RWTH Aachen Transmission Expansion Problem Benchmark Case
RWTH Aachen has published A Benchmark Case for Network Expansion, which is "derived from the IEEE 118 bus network and modified in accordance with European standards such as a nominal frequency of 50Hz, the use of conventional voltage levels, and conductor dimensions."
Registration is required to download the model.
The paper describing the model is A benchmark case for network expansion methods, 2015.

Typical transmission line electrical parameters
European 50 Hz transmission
The main European alternating current (AC) electricity system is operated at 50 Hz. (Other networks, such as those for electrified trains, operate at other frequencies and some transmission lines use direct current.)
On the continent AC transmission voltages are typically 220 kV or 380 kV (sometimes quoted as 400 kV, since network operators often run their grid above nominal voltage to reduce network losses).
220 kV overhead lines are typically configured with a bundle of 2 wires per phase with wires of cross-section Al/St 240/40.
380 kV overhead lines are typically configured with a bundle of 4 wires per phase with wires of cross-section Al/St 240/40.
We now list the impedances for the lumped pi model of the transmission lines.

In the table the current limit is calculated as 645 A per wire at an outside temperature of 20 degrees Celsius.

Combining electrical parameters for multiple circuits
In the table above, the impedances are quoted for a single circuit. The resistance and inductances are in series, so decrease proportional to the number of parallel circuits (roughly - the geometry changes mean the series inductances is slightly modified). Similarly the capacitance is in shunt so increases proportional to the number of parallel circuits (again, roughly because of changing geometry).
