METHOD AND SYSTEM TO INFLUENCE THE POWER GENERATION OF AN ADJUSTABLE SPEED GENERATOR
First Claim
1. A method to influence a power generation of at least one adjustable speed generator, where the at least one adjustable speed generator provides power at constant frequency to a local AC bus, the local AC bus being connected via a first voltage source converter to a DC link which in turn is connected via a second voltage source converter to an AC grid, the method comprising:
- controlling via the first voltage source converter an AC voltage in the local AC bus; and
modifying a reference value for a AC voltage magnitude of the local AC bus in dependence on a AC voltage magnitude of the AC grid.

Abstract
A method and a system to influence the power generation of at least one adjustable speed generator. The system includes a first voltage source converter connected to a local AC bus. The local AC bus is provided with power by the at least one adjustable speed generator. A second voltage source converter connected to an AC grid. A DC link is connected between the first and the second voltage source converter. At least one control unit controls the first and the second voltage source converters. The at least one control unit performs the method to control the AC voltage in the local AC bus via the first voltage source converter and to modify a reference value for the AC voltage magnitude of the local AC bus in dependence on the AC voltage magnitude of the AC grid.
