Central management device for wind measurement masts

Abstract

An embodiment of the application discloses a central management device for wind measurement masts which is used for checking completeness and validity of wind measurement data and capable of timely discovering failure of a sensor of a wind measurement mast. The central management device comprises a sensor, a processor, a storage, an input / output device and a bus; the sensor, the processor, the storage and the input / output device are connected with the bus; the sensor is used for cyclically acquiring wind measurement data of a wind measurement mast according to a first preset duration threshold; the processor is used for detecting whether the wind measurement data are complete; if not, detecting missing data information in the wind measurement data, and transmitting the information to a user terminal; if yes, detecting validity of the wind measurement data, and analyzing invalid data and valid data obtained; generating a wind measurement data analysis report according to the invalid data and valid data; uploading the measurement data and the wind measurement data analysis report to a wind data resource library.

Description

technical field [0001] This application relates to the technical field of wind power data analysis, in particular to a centralized management device for wind measuring towers. Background technique [0002] Assessing the wind energy resources of a wind farm needs to rely on field wind measurement data. Before evaluating the wind energy resources of a wind farm, it is necessary to establish a wind measuring tower in the wind farm for wind measurement. The wind measuring tower is erected in the target wind field and is a tall tower structure used to measure wind resource parameters. Various anemometers, wind vanes, temperature, air pressure and other monitoring equipment as sensors are installed at different heights of the tower body, and the measurement data are recorded and stored in the data recorder installed on the tower body. [0003] There are a large number of enterprise-level wind measuring towers, usually in the thousands. The current monitoring method for wind measu...

Problems solved by technology

[0004] Since the management personnel need to open the mailbox to export the wind measurement data for monitoring, it is only when the wind measurement data is exported that some sensors are found to be faulty, resulting in incomplete measured data (that is, missing data due to partial data loss). Some of the data is invalid, and the amount of monitored data is huge, which also leads to managers sometimes not being able to find incomplete wind measurement data and some invalid data in time, resulting in low-accuracy data results after the test. The tower cannot be maintained in time and the management efficiency is low.
