Description
Technical Field
The invention relates to the technical field of wind direction instrument installation zeroing of wind generating sets, in particular to a zeroing device and a zeroing method for a large-scale semi-direct-drive unit anemoscope.
Background
At present, the wind direction indicator of the wind generating set adopts a manual zero setting mode in the installation process and the operation and maintenance process, as shown in fig. 6, the zero scale line of the wind direction indicator is corrected and parallel to the axis of the hub by virtue of the experience of technicians, and because human sense organs hardly accurately judge whether the zero scale line of the wind direction indicator is parallel to the central axis of the engine room or not, a fan cannot accurately align to the incoming wind direction, the situation of inaccurate zero setting can lead to the integral right shift of the power curve of the generating set, and the generating capacity of the generating set is directly influenced, as shown in fig. 7.
When the wind generating set is designed, the included angle between the actual axis of the engine room and the wind direction is zero degree, when the wind direction of the incoming wind is not deviated from the axis of the engine room, the Power obtained by the fan impeller is Power1, when the wind speed is unchanged and the wind direction deviation angle is theta, the Power obtained by the fan impeller is Power2, and the two formulas are satisfied: power2=power1×cos3θ. When the wind direction deviation angle theta is 2 degrees, the loss of the generated energy is about 2 per mill, and for a wind field with the capacity of 50MW and the annual availability time of 2000 hours, the generated energy of 200000KW.h can be increased, namely the income of about 100000RMB can be increased.
Accurate wind direction signal can be given to the fan to the accurate wind direction of anemoscope, and when fan and incoming wind direction were inaccurate, impeller skew wind direction can lead to the impeller and even the mechanical load unbalance of whole fan, and this kind of load can be much bigger than other loads, if can reduce, just can prolong fan life, perhaps let current fan drive bigger impeller.
Through the analysis, a more accurate and reliable zeroing device and method are needed to zeroe the anemoscope of the fan, so that the wind wheel of the unit can be accurately aligned with the incoming wind direction, and the performance and the generated energy of the unit are improved.
