Understanding how turbines and site interact了解风机与风电场之间的相互作用• Historically, offshore data are rare and of poor quality because: 纵观历史，海洋数据稀缺且质量不高：

• Equipment is typically, unsupervised, remote and in a harsh environment

设备通常无人监管、或地处遥远，且较恶劣的海洋环境中• Equipment is dangerous and expensive to maintain 设备安全无保障、且维护费用昂贵• Consequently, offshore

wind farm operation is more risky than onshore, as the environment is generally less well understood

由于对海上环境知之甚少，相比 于陆上风电场，海上风电场运行 更具风险

Prevention is Better than Cure 防患于未然• Site Characterisation, can we afford to take risks? 了解风电场特性，我们能够承担风险吗？

Power Performance Assessment Offshore 海上风电场风机功率表现评估• The need to verify the compliance of assets offshore using power

performance assessment is more urgent given the costs and risks, yet this is not being observed. 在评估海上风场的资产表现时如何应用功率表现评估方法，及考虑实施成本及风险至关重要，但截至目前为止，未有相关评价

• To comply with current IEC 61400-12 requirements based on mast mounted anemometry it is likely that the cost of a power performance assessment will outweigh the benefits. 根据国际电工委员会（ IEC ） 61400-12 进行测风塔测量，其功率表现评估的成本很有可能超过评估的收益。

• The forthcoming 3rd edition of IEC 61400-12-1 will include detailed provision for remote sensing. 即将出版的 IEC 61400-12-1 第三版将包含有关遥感测量的详细规定。

• Remote sensing using 2nd generation LiDAR such as Galion can be used to produce IEC 61400-12 compliant power curves. 使用第二代激光雷达如Galion 进行遥感观测可测量符合 IEC 61400-12 要求的功率曲线。

• Remote sensing will also facilitate a better understanding of wind flow and wake behaviour generally in the offshore environment. 遥感技术也将为我们更好的认识海上环境风流及尾流提供便利条件。

Performance MonitoringInspection of performance metrics enables rapid identification of anomalous performance in seconds or minutes. 检查发电量表现指标可以在几秒或几分钟内快速识别发电量异常现象。
