Bayesian optimization for multi-screw archimedes turbine design

位于安大略德里的Bluestreak设备公司正在开发阿基米德螺旋式水力发电机（ASG），这种发电机可以在安大略沿岸的数千个低水头（1- 10米）地点使用。在过去十年中，欧洲安装了数百个助理秘书长，还有更多的助理秘书长正在开发中。ASG与其他水力涡轮机相比具有商业竞争力，对环境的影响非常低，包括对鱼类的影响。在过去的六年里，Bluestreak研发了阿基米德螺旋发电机技术，并成功安装了北美第一个并网的阿基米德螺旋水电站。他们目前正在商业化他们的ASG系统，并有几个在不同的规划阶段。Bluestreak和大卫卢比茨教授（圭尔夫大学）开发并验证了一个精细的工程模型，可以可靠地预测指定阿基米德螺旋系统的功率输出。该模型可以迭代地用于优化特定场地的单个阿基米德螺旋发生器的内部收益率，这也是Bluestreak在微型水力发电领域的商业优势的关键部分。圭尔夫大学的Graham Taylor博士的研究团队通过Engage和Engage Plus项目与Bluestreak合作，取代了费力的手动参数调整，以找到最佳地点-使用基于贝叶斯优化的解决方案进行特定配置。从那以后，Bluestreak开始考虑在每个站点安装多个螺钉。因此，这个为期2年的CRD旨在将当前的框架扩展到同时优化多个阿基米德螺旋涡轮机（AST）的实际情况。我们还将开发性能模型和优化器的改进（与单螺杆和多螺杆相关）。该项目旨在使Bluestreak的系统更具竞争力，同时推进工程设计全局优化的最新技术。

Bluestreak Equipment, of Delhi, Ontario, is developing Archimedes screw hydro generators (ASGs) that could be utilized at thousands of low head (1-10m) sites along waterways just in Ontario. Several hundred ASGs have been installed in Europe in the past decade, with more in development. ASGs are commercially competitive with other hydro turbines, with very low environmental impacts, including on fish. In the past six years, Bluestreak researched and developed their Archimedes screw generator technology, and successfully installed the first grid-connected Archimedes screw hydro plant in North America. They currently are commercializing their ASG system and have several more in various stages of planning. Bluestreak and Prof. David Lubitz (University of Guelph) have developed and validated a refined engineering model that can reliably predict the power output of a specified Archimedes screw system. The model can be used iteratively to optimize the IRR of a single Archimedes screw generator for a specific site, and is a key part of Bluestreak's business advantage in the microhydro field.Dr. Graham Taylor's research team at the University of Guelph collaborated with Bluestreak through Engage and Engage Plus projects to replace the laborious laborious manual tuning of parameters to find an optimal site-specific configuration with a Bayesian Optimization-based solution. Bluestreak has since moved to consider multiple screws installed per site. Therefore, this 2 year CRD aims to extend the current framework to the practical case where multiple Archimedes screw turbines (ASTs) are optimized simultaneously. We will also develop improvements to the performance model and optimizers (relevant to both single- and multi-screw). The project aims to make Bluestreak's system more competitive while advancing the state-of-the-art in global optimization for engineering design.
