Turbine System Design
WRE Ltd has built up significant expertise in the design of screw turbine systems. These are preferred by the Environment Agency where applicable, but can have particular issues. They are very sensitive to head and tail water level variation, and poor design or understanding of these issues can typically cause noise problems at low flows, power quality problems at low power (causing the system to have difficulites remaining connected to the national grid), and underperformance at optimum conditions.
At WRE Ltd we understand these issues, and ensure that we gather sufficient data via the use of multiple logging sensors stationed on site during the design process. This allows us to complete in-depth analysis to ensure that the design is tailored to the specific site conditions.
In addition to screw turbines, WRE Ltd have significant experience of higher head systems using both crossflow turbines and Pelton turbines with a number of installations throughout the country
