High Voltage Network Expansion

Main content

The aim of this activity is to evaluate two alternative grid expansion plans in the Zurich regional network with regard to system security at the 380/220/150/132 (SBB) kV voltage levels. The analysis consists of load flow simulations, N-1 security calculations and selected N-2 outage scenarios. In particular for N-1 security calculations outages for all 220 kV lines and for all transformers feeding into the 150 kV urban grid are considered. The N-2 outage scenarios consist of cases where a given system component is out of service for maintenance work. For each such case the aforementioned N-1 security calculations are then successively performed.
