Sample interview questions: How do you evaluate and select appropriate turbine systems for different hydroelectric projects?
Sample answer:
When evaluating and selecting appropriate turbine systems for different hydroelectric projects, several factors need to be considered. These factors include the project’s specific requirements, site conditions, available water resources, environmental considerations, and economic viability. By carefully analyzing these aspects, a hydroelectric engineer can make an informed decision on the most suitable turbine system for the project.
-
Project Requirements: Understanding the project’s objectives, such as desired power output, operational flexibility, and expected lifespan, is crucial. Different turbine systems have varying efficiencies, capacities, and capabilities, so aligning these factors with the project’s requirements is essential.
-
Site Conditions: Evaluating the site characteristics is vital in determining the type of turbine system to be used. Factors such as the head (vertical distance between the water source and turbine), flow rate, and available space can influence the turbine selection. For example, low head sites may require a different turbine design than high head sites.
-
Water Resources: Evaluating the available water resources is necessary to determine the turbine system’s suitability. This involves analyzing the water source’s flow variability, seasonal changes, and sediment content. These factors influence the choice between a run-of-river or storage-based system, as well as the design parameters of the turbine.
-
Environmental Considerations: It is important to assess the environmental impact of the turbine system. Evaluating potential effects on aquatic life, fish passage, and downstream flow regime is essential for sustainable project development. Choosing a turbine system that minimizes these impacts through fish-friendly designs or fish passage structures should be prioritized.
-
Economic Viability: Evaluating the economic feasibility of different turbine systems is crucial. This involves assessing the initial investment cost, expected energy … Read full answer
