Device and method for checking the electro-dynamic behavior of a drive train of a power generating device on the network

摘要

The invention relates to a device for testing the electro-dynamic behavior of a drive train of a power generating device on the network, in particular a wind turbine on the grid at transient network errors, wherein the test drive train at least one generator for generating electrical power and at least one inverter for feeding the electrical power of Generator in an electrical network, and the device additionally comprises connection means for connecting the inverter to an electrical network, an electrical load for the drive train is provided and the device comprises at least one network error unit for simulating transient network errors and a flow control, with which at least the drive train and the network error unit can be controlled. The object to provide a device for testing the electro-dynamic behavior of a drive train of a power generating device on the grid at transient network faults to available, which can cost-effectively test different powertrains of different power classes on their electro-dynamic behavior in network faults is solved, in that means are provided for driving the generator, which have at least one flywheel mass accumulator for storing kinetic energy and the at least one flywheel mass accumulator can be coupled to the generator via a drive shaft.
