This dataset is developed for the wide-frequency impedance characteristic analysis of offshore wind turbines, addressing the technical challenge of enhanced wide-frequency dynamic interaction between the turbine and power grid with the expanding grid-connected scale of offshore wind power. The data is generated based on a Hardware-in-the-Loop (HIL) platform composed of grid simulation device controller (ACS), RTDS real-time simulation system and RTLink. Impedance testing is implemented by injecting positive-sequence/negative-sequence wide-frequency disturbances into the system via ACS, combined with the built-in frequency scanning analysis module of RTDS. The data originates from comparative simulations of an 18MW wind turbine under 20% and 90% rated active power operating conditions, when connected to an ideal power grid and a grid simulation device respectively. It covers wide-frequency disturbance scenarios from 1Hz to 1000Hz, focusing on simulating the response process of the wind turbine to wide-frequency disturbances under different loads. The main content of the dataset includes transient recording data of positive-sequence/negative-sequence voltage and current at the Point of Common Coupling (PCC), as well as key characteristic quantities of impedance amplitude and phase such as Zpp (positive-sequence impedance) and Zpn (positive-negative sequence coupling impedance) calculated via Fast Fourier Transform (FFT) analysis, which clearly presents the differences in impedance characteristics of the wind turbine across different frequency domains. This dataset provides core data support for verifying the injection accuracy of wide-frequency disturbances by grid simulation devices, analyzing the wide-frequency stability of wind turbines and optimizing weak grid adaptability test methods, with a total size of 691MB.
