摘要： The invention relates to a method to stabilize an electrical grid, which is subjected to a grid fault, by a wind energy installation like a wind turbine or a wind farm.
A deviation of the grid frequency (Delta_f) from a nominal frequency is determined at a connection point of the wind energy installation with the electrical grid. The grid frequency deviation (Delta_f) is counteracted by an active current, which is fed by a frequency converter of the wind energy installation to the electrical grid. The deviation of the grid voltage (Delta_U) from a nominal voltage is determined at the connection point. The grid voltage deviation (Delta_f) is counteracted by a reactive current, which is fed by the frequency converter of the wind energy installation to the electrical grid. The grid frequency deviation (Delta f) and the grid voltage deviation (Delta_U) are determined at the same time and the active current and the reactive current for the respective counteraction are determined in dependency of each other and in dependency of the maximum current of the frequency converter.摘要翻译： 本发明涉及通过诸如风力涡轮机或风力发电场的风能设备来稳定受到电网故障的电网的方法。 在风电装置与电网的连接点处确定电网频率（Delta_f）与标称频率的偏差。 电网频率偏差（Delta_f）由有功电流抵消，该有功电流由风能设备的变频器馈送到电网。 在连接点确定电网电压（Delta_U）与标称电压的偏差。 电网电压偏差（Delta_f）由无功电流抵消，无功电流由风能设备的变频器馈送到电网。 在同一时间确定电网频率偏差（Δf）和电网电压偏差（Delta_U），并且相应的反作用的有功电流和无功电流依赖于彼此并且依赖于 频率转换器。
