The stationary part of structure is measured, the two is also a coaxial configuration.I.e. the rotating part of the azimuthal measurement structure of impeller with it is static
Part is a coaxial configuration.According to IEC 61400-1 standard requirements, azimuthal 0 ° of impeller rotates for a blade in impeller
Angle when in plane vertically upward.For slip ring high-precision encoder measurement method, due to slip ring high-precision encoder
For an increment type output valve, therefore it cannot judge the azimuthal relatively described 0 ° of azimuthal angle of wind power generating set impeller
Degree；And if not being aligned with a blade central axes close to switch measurement methods measurement phase close to switch for multiple,
Debugging initial stage does not calibrate zero-bit and compressor emergency shutdown power-off etc. under the unsaved situation of reasons initial value, after unit operation its
Measured value and a deviation is actually always existed, and reasons are likely to be in a stochastic regime to the deviation at any time etc..
Summary of the invention
It is an object of the invention to overcome the above problem, 0 ° of impeller azimuth value can accurately be refreshed automatically by providing a kind of measure
The azimuthal measurement method of wind power generating set impeller.
The technical scheme is that a kind of azimuthal measurement method of wind power generating set impeller comprising following step
Suddenly：
Step 1, real-time measurement impeller azimuth continuously measure a blade from 0 ° to 360 ° of initial angle of azimuthal angle
Angle value；
Impeller azimuth angle value when 0 ° of the impeller azimuth that step 2, measurement IEC standard require measures a blade rotation
Impeller azimuth angle value when going to the blade central axes vertically upward；The rotating part of the azimuthal measuring device of impeller with
Stationary part is a coaxial configuration, and impeller often rotates a circle, and the azimuthal measuring device induction of impeller is primary, impeller azimuth
Measuring device will obtain a pulse signal, the position of the signal designation is the azimuthal 0 ° of azimuth position of impeller；
Step 3 obtains the impeller that the time step 1 is reset when the instruction of 0 ° of azimuth signal based on IEC standard requirement in step 2
Azimuth is 0 °；
Step 4, the impeller azimuth for obtaining step 1 are exported after step 3 resetting to get the impeller side of wind power generating set is arrived
Parallactic angle.
Preferably, the impeller azimuth is measured by close switch, azimuthal in the measurement impeller
Rotating part installs one close to switch, and the close switch is coaxial with the central axes of one of blade, in measurement impeller side
The structure stationary part of parallactic angle is arranged with close to the exploration hole to match is switched, and impeller often rotates a circle, close to switch and detection
