their measurement will require respective models for their evaluations to used
the monitoring WPD.
For the density measurement it is necessary the air temperature reading is
needed.
3.2.3. Indicators
As shown on figure 4 the monitoring of wind power plant is based on the
number of indicators. The definition of each indicator is specified by the
respective wind power model as presented in following description:
1 Wind Power Density
These evaluation lead us to the definition of the tree parameters to be as
the monitoring of the Wind Power Density, namely: pressure and temperature
of the air, average wind velocity and frequency of the wind.
2 Efficiency of wind power plant
Mechanical energy obtained by the wind energy is converted to the
electricity by the electric generator with respective efficiency defined
respective efficiency defined by
η = WDP
.
A / E
power
(4)
Monitoring parameters are: WDP and E
power
3 Power frequency
Power frequency is parameter needed for the wind power plant
synchronization. Together with electric power measured by the electric
currency in amperes and grid voltage in volt, it is a stability constrain for the
connection to the grid. I require mentoring of following parameters: frequency
fluctuation and voltage fluctuation in the grid.
4 Electricity cost
Cost of the electricity produced by the wind power plant is defined as the
total amount of plant expenses divided by power produced. The expenses are
defined by the cost of manpower and maintenance cost.
