Micrositing

Once the whole project has been assembled it is time to do the micro-siting study.

Once the whole project has been assembled, that is, there is a Clima object with met mast statistics, there are wind resource maps with all grid points properties and a new wind farm has been created, it is time to do the micro-siting study, and in particular, the energy yield calculations.

Wake models and wake effects

There are eight wake models that can be used to run the energy yield calculations. Regarding wake effects, this modules allows recreating the whole wind field for a particular sector including the wake induced wind.

Furowake

FUROW includes a CFD far wake model based on the optimisation of the previous version UPMPARK developed by Polytechnic University of Madrid. This model is coupled with a near wake model that reproduces the pressure distribution as well as the velocity field near the rotor.

Energy yield

Energy yield calculations are based on the maps calculated on the previous stage of wind resource calculation as well as in the Clima object. Once those are defined, wind turbines are set on the desired positions and wake model is chosen to calculate wake losses. Moreover, DRIX correction can be applied in case of complex terrain.

Energy report of the project

As the most complete wind software, Furow provides all the information of the project with a final energy report including meteorological information and energy figures for the whole wind farm and each individual wind turbine.

Uncertainty analysis

Uncertainties in a wind project comes from different sources. In Furow these uncertainties are classified in those coming from wind speed and direction, and others from wind farm configuration and performance.

Site compliance

Within the micro-siting menu, it is possible to evaluate IEC parameters to check the class and subclass for each position of the wind farm.

Wind farm power curve

A wind farm power curve indicates the power level of a given wind farm for every wind speed and direction measured at any point of the site.

Sector management

Within the Wind farm object properties, there is a tab where it is possible to manually implement a wind sector management strategy to stop wind turbines for certain wind speed and direction ranges.

Site distorsion

Measurements of the meteorological mast may represent a distorted flow caused by wind turbines rotation. In those cases it is necessary to correct wind measurements of wind speed and wind speed standard deviation with the wind speed deficits and added turbulence created by the wind turbines.

Wind farm noise calculation

With this module, the user can estimate the noise level of a wind farm and determine the areas affected by excessive noise caused by the wind turbines. In this way it will be known if the chosen site is suitable considering the effects of the noise to near living areas as certain noise levels must not be exceeded according to standards of each country.

Economic and financial module

On this module of Furow the user will be capable of making a full financial assessment of the wind farm which is being developed in order to determine its future economic viability as well as the profitability of the project and shareholders. Based on the fixed and operating costs, the generated revenues and different financial assumptions, an excel file with a financial report is generated including the operational cashflow, balance sheet, income statement, etc. and profitability parameters.
