dc.description.abstractSolvSim Power Station (SSPS) is a hard-ware-in-the-loop simulator that can be utilized to test and prepare power stations for island operation. SSPS has been successfully used in Sweden over the past decade. During the test, the power station remains connected to the grid without the need to establish an actual island system. SSPS requires the tested power station to be synchronized to a strong grid. The principle of SSPS is to replace the normal frequency feedback of the governor with a simulated frequency. This thesis investigates the in uence of grid frequency variation on the test. Two scenarios of frequency variation is considered; 1) spontaneous frequency variation in large grid 2) grid frequency variations as a consequence of the test. In this thesis, a model of a power station connected to a grid with a variable frequency is implemented. SSPS tests are performed on the power station using a model of SSPS. The results of this thesis demonstrates that SSPS is dependent on the rate of change of frequency (RoCoF) of the grid rather active power output of the generating is used as an input during the test. The results also show that the in uence of grid frequency variation on SSPS tests is insignificant for both scenarios.
