Consider following factor：The size of output power of wind power generation is related with the inswept area of wind speed, atmospheric density and wind wheel, wherein wind speed pair
Wind-driven generator power output plays a decisive role.
Only consider wind speed ideally, power out-put characteristic as shown in Fig. 2, its power out-put characteristic mathematics
Expression formula can be described as：
Wherein, PRFor rated power, vinAnd voffIt respectively refers to the incision of wind turbine and cuts out speed, vRFor rated wind speed.
In view of the output characteristics of wind-power electricity generation, defining three kinds of operational modals is respectively：Stop mode, maximum power with
Track (MPPT) mode and constant output mode, such as table 1：
The action of 1 wind power generation unit of table and change condition for operational modal conversion
The operating status of wind-power electricity generation can be divided into following four according to the difference of wind speed：
Wind speed is cut when wind speed is less than unit, is not enough to drive wind wheel blade rotation, wind-driven generator will not work, idle
Rate exports, i.e., when change condition is t1, acts p1.
When wind speed is between incision wind speed and rated wind speed, unit operation is in part output state.But due to wind-force
Generator may operate in maximum tracking mode (MPPT), realize that the maximum conversion of wind power is moved that is, when change condition is t2
Make p2.
When wind speed be between rated wind speed and cut-out wind speed when, wind-power electricity generation chance due to its unit capacity limitation,
