Survey of Robustness Measures in Electrical Designs in Nuclear Power Plants
| 2018:519 | G. Lindahl, E. Nyholm, T. Schütte
In this study the electrical connection of the different nuclear power plants in Finland and Sweden has been reviewed in terms of their single line diagrams and how they are connected to the grid.
Means of diversifying the connection to the grid using other connections, such as cross-coupling, connection to both off-site switchgears etc. has been discussed showing some possible ways of increasing robustness by means of not connecting all electrical trains to the same source.
Motor generating sets, MG-sets, as a mean of isolating the electrical system of the plant from the off-site power system has been identified as a good measure and no common cause failures have been identified.
