| 发明名称 | Turbine array and a method of controlling a turbine array during a loss-of-grid event | ||
| 摘要 | A turbine array including: a plurality of turbines; an electrical machine connected to each of the turbines and to an electrical grid; wherein at least one of the electrical machines is a motor-generator which can operate in a motor mode or a generator mode, and wherein the other electrical machines are generators; and a controller for detecting a loss-of-grid event; wherein the controller sets the motor-generator to the motor mode when a loss-of-grid event is detected, the motor-generator being driven by the generators and thereby providing a load to the generators. | ||

| 主权项 | 1. A tidal or tidal stream turbine array comprising: a plurality of tidal or tidal stream turbines together creating a local grid; an electrical machine connected to each of the turbines and to an electrical grid; wherein at least one of the electrical machines is a motor-generator which can operate in a motor mode or a generator mode, and wherein the other electrical machines are generators; and a controller for detecting a loss-of-main-grid event; wherein the controller is configured to switch motor-generator to the motor mode when a loss-of-main-grid event is detected, the motor-generator being driven by the generators and thereby providing a load to the generators, thereby allowing the generators to drive the motor-generator via local grid power. | ||
