Iced Wind Turbine Control Optimization

自2010年以来，Senvion已经在魁北克安装了200多台MM82/92 2.05 MW寒冷气候版本（CCV）风力涡轮机，这些涡轮机暴露在低温和中等到严重的结冰条件下。风力涡轮机叶片上的冰积可能会导致空气动力学和质量失衡，从而导致产量损失以及极端负荷的增加。该项目的主要目标是优化Senvion涡轮机的冰运行模式，以最大限度地提高能源产量，同时确保最大限度地降低高极端负荷的风险。更具体地说，该项目旨在改善冰检测，验证冰诱导载荷，并优化结冰事件期间的涡轮机控制参数。这些目标将通过对目前在魁北克两个风电场运行的四台Senvion MM92 CCV风力涡轮机进行测量活动来实现，这些涡轮机暴露在中度和重度结冰条件下。涡轮机配备了额外的气象、冰和负荷传感器。数据将被分析并用于表征结冰事件和验证负载假设。根据分析和仿真结果，对水轮机冰态运行模式进行优化。预计到该项目结束时，Senvion涡轮机的冰运行模式将大大改善，为上述制造商在日益增长的加拿大风能市场（主要是在寒冷气候中）提供竞争优势。由于优化的冰运行模式，风电场所有者将最大化他们的资产，加拿大电网将更加稳定，从而导致可再生能源的更大渗透。

Since 2010, Senvion has installed a fleet of more than 200 MM82/92 2.05 MW Cold Climate Version (CCV)wind turbines in Quebec which are exposed to low temperatures and moderate to severe icing conditions. Iceaccretion on wind turbine blades may cause aerodynamic and mass imbalances that can lead to productionlosses as well as increased extreme loads.The main objective of this project is to optimize the ice operation mode of a Senvion turbine in order tomaximize energy yield while ensuring a minimal risk of high extreme loads. More specifically, the project aimsto improve ice detection, validate ice induced loads, and optimize turbine control parameters during icingevents.These objectives will be achieved by conducting a measurement campaign on four Senvion MM92 CCV windturbines currently operating at two wind farms in Quebec, and which are exposed to moderate and severe icingconditions. The turbines are equipped with additional meteorological, ice and load sensors. The data will beanalyzed and used to characterize icing events and validate load assumptions. The turbine's ice operation modewill be optimized based on the results of analysis and simulation.It is expected that the ice operation mode of Senvion turbines will be greatly improved by the end of thisproject, providing the said manufacturer with a competitive edge in the growing Canadian wind energy market,which is predominantly in cold climate. As a result of an optimized ice operation mode, wind farm owners willmaximize their assets and the Canadian power grid will be more stable, leading to greater penetration ofrenewable energy.
