Abstract:
1. A method for operating a power system comprising: generating electrical power with an electrical generator of a wind power installation driven by a rotor to output the electrical power to an electrical grid; sensing an electrical current of the electrical power outputted to the electrical grid to detect a fault in the grid; maintaining connection of the wind power installation to the grid during the fault to continue to supply electrical current to the grid from the wind power installation during the fault; limiting the electrical current delivered by the wind power installation to the grid during the fault to less than a selected amount; controlling the wind power installation from a control station distant from the wind power installation to remotely adjust the amount of electrical current delivered by the wind power installation to the grid during the fault; and resuming normal function of the wind power installation when the fault is no longer in the grid.
