Abstract

This paper describes the Fault Ride Through (FRT) capability of generators of a part of the 132 kV high voltage power network in Telemark region, Norway using a simplified power system simulator model. The organization, “European network of transmission system operators for electricity” (ENTSO-e) is introducing a network code for the Transmission System Operators (TSO) in Europe where the upper limit of the FRT requirement for 132 kV system is 0.25 s. However, according to the Norwegian network code, this limit is 0.40 s. The generators in the Norwegian power system are located in a distributed network and most of these are hydropower generators. The simulation results show that the structure of the Nordic power system enhances the system stability. The dynamic model of the power network is developed by using DIgSILENT PowerFactory simulation tool.
