海上风电交直流并网故障特征仿真数据集

本数据集主要面向海上风电并网系统故障分析与保护策略研究需求建设，基于PSCAD/EMTDC电磁暂态仿真平台产生。数据源于对永磁直驱风电机组通过交流海缆、交流架空线及柔性直流三种典型方式并网的精细化建模，系统设置了36种组合工况，精密模拟了不同故障位置、风电出力、线路参数与故障深度下的电网故障场景。数据主要内容包括并网点三相电压、电流的瞬时录波数据，以及从中提取的暂态过电压峰值、衰减时间、振荡频率等关键特征量，完整记录了故障全过程的动态响应特性。该数据集为研究海上风电并网系统的故障穿越能力、暂态过电压机理及保护配合优化提供了高精度、多场景的仿真数据基础，数据量约为148MB。

This dataset was developed to meet the research requirements of fault analysis and protection strategy optimization for grid-connected offshore wind power systems, and was generated using the PSCAD/EMTDC electromagnetic transient simulation platform. The data is derived from refined modeling of permanent magnet direct-drive wind turbines grid-connected via three typical schemes: AC submarine cables, AC overhead transmission lines, and flexible high-voltage direct current (HVDC) systems. The simulation system has configured 36 combined operating conditions, and accurately simulates power grid fault scenarios under different fault locations, wind power output levels, line parameters and fault depths. The main contents of the dataset include instantaneous recording data of three-phase voltage and current at the grid connection point, as well as key characteristic quantities extracted therefrom, such as transient overvoltage peak values, decay times, oscillation frequencies and other critical metrics, which fully record the dynamic response characteristics throughout the entire fault process. This dataset provides a high-precision, multi-scenario simulation data foundation for researching the fault ride-through (FRT) capability, transient overvoltage mechanism and protection coordination optimization of offshore wind power grid-connected systems, with a total data volume of approximately 148 MB.
