Distributed hydrokinetic power generation for remote community applications in cold climates

在加拿大，84%的电力、热力和交通能源来自化石燃料；对于偏远社区来说，能源需求主要由化石燃料提供。能源驱动因素-导致气候变化、石油峰值、环境排放、长期能源安全和可持续性的温室气体-要求我们的社会开发具有成本效益的技术组合，以便利用可再生能源，并提高我们社区使用的可再生能源的比例。本次探索补助金续期中提议的活动旨在开发海洋工业所需的新技术，以实现较低的统一成本，并满足该行业为可持续社区提供河流和潮汐水力涡轮机所需的实际要求。一种新的坚固耐用的仪器将被开发出来，用于在潜在的河流涡轮机地点测量长达两年的速度，以预测发电量。这台新仪器将在加拿大水动力涡轮测试中心(CHTTC)进行现场测试，数据将用于建立预测速度分布、能力系数和累积水速分布(2MSc)的表达式。CHTTC流道的特点是同时测量二维平面上的速度，通过声学多普勒风速仪穿越水柱，并使用微结构剖面仪。这将是第一次在高速河流位置(2毫秒)进行如此详细的速度和湍流测量。将为寒冷气候下的流体动力河流应用建立新的1千瓦部署系统的模型、制造和测试，以简化部署并实现涡轮机在水流中的稳定性。其目的是在寒冷气候的可持续社区全年运行船用涡轮机时，显著降低统一的电力成本(1个博士学位)。将在CHTTC对Darrieus涡轮机进行数值建模和实验测试，以了解如何优化涡轮机的位置以最大限度地提高功率生产(1 PhD)。拟议的研究计划的价值在于，通过以低于替代方案的统一成本运营水力涡轮机，使生活在寒冷气候中的社区变得自力更生和可持续。

In Canada 84% of our energy for electricity, heat and transportation comes from fossil fuels; for remote communities, energy needs are mainly supplied by fossil fuels. Energy drivers---greenhouse gases that lead to climate change, peak oil, environmental emissions, long term energy security and sustainability---require our society to develop a portfolio of technologies that are cost effective in order to harness renewable energy and increase the percentage of renewable energy used in our communities. The activities proposed in this Discovery Grant renewal are directed towards developing novel technologies that are required by the marine industry to achieve lower levelized costs and to address practical requirements needed by the industry to provide sustainable communities with river and tidal hydrokinetic turbines. A new, rugged instrument will be developed to measure velocities for up to 2 years at potential river turbine sites to predict power production. This new instrument will be tested in-situ at the Canadian Hydrokinetic Turbine Testing Center (CHTTC) and the data will be used to develop expressions to predict velocity distribution, capacity factors and cumulative distribution of water velocities (2 MSc). The CHTTC flow channel will be characterized by simultaneously measuring velocities in 2-D planes, by traversing the water column with acoustic Doppler anemometry, and by using a microstructure profiler. This will be the first time such detailed velocity and turbulence measurements are made in a high velocity river location (2 MSc). A new 1-kW deployment system for hydrokinetic river applications in cold climates will be modeled, manufactured and tested to simplify deployment and achieve turbine stability in the flow. Its purpose is to significantly decrease the levelized cost of electricity when operating year round marine turbines in sustainable communities in cold climates (1 PhD). Numerical modeling and experimental testing of Darrieus turbines at the CHTTC will be performed to understand how to optimally position turbines to maximize power production (1 PhD). The value of the proposed research program is to allow communities living in cold climates to become self-reliant and sustainable by operating hydrokinetic turbines at levelized costs that is lower than alternatives.
