Applicability Analysis

Add applicability analysis function. The function integrates the latest hydrodynamics and multibody dynamics simulation technology to replay the influence of complex terrain on turbine running state. The funciton aims at timely identification and management of applicability risks of turbine model selection.

Operations are as follow:

  1. Open the operation pane: Click a WTG group and switch to the operation pane to open the applicability calculation page.
  2. Select calculation method according to terrain complexity. If all the turbines located on uncomplicated terrain, select RANS, otherwise select DES. Details of operation panel setup please check the user manual via this link.
  3. Select multiple component groups: Click the Set button in the Component Group Setup area and click Configuration on the overview page to select component groups.
  4. Click applicability calculation page to check the result.

PV

  1. Add PV economic evaluation model.

    Tip

    Annual operation cost is recommended to be set as 30~60rmb/kW/year.

  2. Add optimal tilt angle, equivalent full load hours, terrain slope and aspect in solar resource grid.

    Tip

    Optimal tilt angle means the angle between the module plane and the horizontal plane when the south-facing photovoltaic module obtaining the maximum irradiation.

  3. PV array can be displayed on GIS.

WRA

  1. The tower load is reduced by 8%. The relevant instructions are added on the front page of the load list
  2. Noise map supports exporting kml and map file.
  3. Buildings data supports exporting kml file.

3D GIS

  1. Add wind farm 3D effect.

  2. 3D map can display terrain profile.

Economic Evaluation

Economic evaluation supports economic evaluation under the price of reasonable hours in the whole life cycle.

If the reasonable hours in the whole life cycle are 36000h and equivalent full-load hours are 2300h，so the subsidy period number of the program is 36000/2300=15.65 yrs.
