Forecast Statement 2007-2013 Model Files
The following data files represent the network models used to create the powerflow diagrams in Appendix J of Transmission Forecast Statement 2007-2013. They are in ASCII format and can be read directly into the power system modelling software, PSS/E™ version 30. For information on PSS/E™please refer to the PTI website www.pti-us.com

In the model files all 400 kV, 220 kV and 110 kV transmission stations are referred to by their assigned three letter codes. Click here to view the list of three letter station codes and corresponding station names. Busbars with names that do not correspond to a three letter code are either ‘dummy’ busbars necessary for modelling purposes or 110 kV and lower voltage busbars that do not fall under the jurisdiction of the Transmission System Operator.
The transmission network of Northern Ireland is not represented in the model files, other than the main existing and planned connection points between the Republic of Ireland and Northern Ireland at Tandragee and in Tyrone. In the model files ‘dummy’ generators have been placed at the Tandragee 275 kV station (bus 90020) and at the planned 400 kV station in Co. Tyrone (bus 90340) to simulate the cross-border power flows in each case. Please refer to NIE's most recent Seven Year Transmission Statement for information on the transmission network of Northern Ireland.
The East-West interconnector between Ireland and Great Britain is represented in the 2013 model files as a ‘dummy’ generator at bus 54600, which is connected to the 220 kV busbar at Woodland by means of a zero impedance link. This ‘dummy’ generator has a maximum and minimum power output of 500 MW and -500 MW respectively, positive output representing an import from Great Britain and negative output representing an export to Great Britain. The ‘dummy’ generator was modelled as having a fixed reactive power output of 0 Mvar under the assumption that the interconnector will involve self-compensating HVDC technology.
