摘要 直驱式技术正在成为海上风电机组传动系统采用的主流技术之一, 对其运行状态的实时正确评估显得极为迫切。该文提出一种集成了相关系数法、劣化度分析法和模糊综合评判等多种方法的风电机组运行状态评价模型。采用客观赋权法中的相关系数法来计算指标权重; 归一化指标参数采用劣化度分析法; 利用多层次模糊综合评价法, 自下而上、逐级地对风电机组各个子系统的运行状态进行评价。并对该评价模型进行实际直驱风机在线监测数据的应用分析, 评价结果符合实际运行数据的分析。该文研究结果可为海上风电场直驱式风电机组日常运行维护的管理提供决策辅助, 提高海上风电场运营效率。

Abstract:Direct drive motor systems for offshore wind turbines will improve reliability and reduce maintenance costs. This paper describes a real-time status evaluation model for offshore direct-drive wind turbines. This model integrates the correlation coefficient method, deterioration analyses and fuzzy synthetic evaluation. The correlation coefficient method determines the weights of various indexes. The deterioration analysis normalizes the indicator parameters. The bottom-up, step-by-step, multi-level fuzzy synthetic evaluation method assesses the status of each subsystem of the offshore direct-drive wind turbine. An analysis of online inspection data for a direct-drive wind turbine shows that the model results are consistent with real operational data. This model is helpful for managing routine operations and maintenance for offshore direct-drive wind turbines to improve the operational efficiency of offshore wind farms.
