MASTER THESIS
Background
A distribution system with a large amount of
small hydro power production can cause stability
issues. This thesis will investigate the stability in
a distribution system in the municipality of Voss
kommune.
As of now there are five hydro power plants
connected to the 22 kV grid. In addition, six more
power plants are either under planning/building
or waiting for licences. My task is to propose
requirements for the construction of the new
synchronous generators to satisfy stability of the
power grid.
The thesis is carried out in close cooperation
with Siemens Power Technologies International
(PTI) and Voss Energi.
The model of the system is modeled in the
simulation tool PSS Sincal provided by Siemens
PTI. Some calculations are done in PSS
Netomac and Matlab.
