Abstract
The invention discloses a wind power plant ultrasonic wave wind resource monitoring method. The method includes the following steps that when a clock is started to reckon time, the clock and a clock server at the data receiving end are subjected to clock synchronization; interruption is triggered according to a set time interval, in the interruption process, a site is saved into a stack, and after the interruption returns, the site is popped up from the stack and recovered; an ultrasonic probe starts to transmit a signal so that wind resource data of a wind power plant can be monitored; after the acquired wind resource data are filtered and processed in other mode, received signals are obtained; the ultrasonic probe is used for calculating the wind speed and the wind direction through signal receiving and transmitting time difference between the received signals; a timestamp is added to a result obtained through data calculation, and packaging is performed; the interruption returns to the site, packaging data are transmitted to a master program; after the packaging data are uploaded by the master program, the interruption is triggered again on a next time point. Therefore, wind resources of the wind power plant can be monitored in real time, and the output power fluctuation phenomenon caused by large-scale wind and power centralized grid connection can be effectively monitored.
