Presentation Description: Preliminary siting of wind farms is difficult in Nepal due to high cost license of siting software and inability to consider key parameters such as accessibility, land use scenario etc. Nepal has multiple rich wind resource areas that are located in largely inaccessible and geographically morphed areas.
This presentation elaborates a framework to identify most feasible wind farm site in the pre-project development stage. The methodology follows overlaying key parameters such as elevation, transportation routes, land use policy, geographical terrain to generate an area consisting of numerous project zones. The framework considers multiple wind turbine generators with different rated power capacities and blade lengths to provide flexible and site-specific energy yield estimates. Finally a self-developed spreadsheet turbine sizing and yield calculator toolkit incorporates secondary wind resource data from Global Wind Atlas and power curve of turbines to calculate the wind farm size and energy yield for all wind turbine generators. The final output will also have considered wake effect losses by adopting a commercially accepted turbine distance formula. Each selected project site is given the best suited wind turbine with total farm size, energy production estimates and capacity factors.
The presentation will contain a case study for Mustang District, Nepal.
Methodology: The presentation will consist a interactive demonstration session of both project siting and sizing by the self-developed spreadsheet turbine sizing and yield calculator tool.
Upon completion, participants will be able to create a project area by overlaying various critical project siting parameters such as accessibility, elevation profile, land use profile etc. Thereafter, the participants will also be able to will list potential zones/clusters within the master overlay to perform project sizing.
Upon completion, participants will be able to define parameters for the selection of wind turbine generator. The participants will learn to describe key identifiers such as turbine dimensions, power curve (vs. wind resource) etc. to select best suited turbines for a project zone and make a comparison between each turbine.
Upon completion, participants will be able to size a wind farm capable of being constructed in a project zone and hence the master project overlay. Furthermore, the participants will be able to conduct energy yield estimates of the wind farm by using secondary wind speed data from a reliable source, wind turbine power curve. Also, the participants will be able to define the placement of wind turbines by considering wake effect in the wind farm.
