Wind turbine generator data collection method based on multi-parameter collection device

Abstract

The invention provides a wind turbine generator data collection method based on a multi-parameter collection device. The wind turbine generator data collection method comprises the following steps: step 1, performing data collection according to a sampling rule; 2, processing the collected data according to a processing rule to obtain a characteristic value corresponding to the data; 3, classifying the data according to the characteristic values corresponding to the data; step 4, the classified data is transferred to a to-be-transmitted data queue, a data stack is formed, and the to-be-transmitted data queue comprises a fault data queue, an abnormal data queue and a normal data queue; 5, performing data transmission on the obtained data stack; according to the scheme, through the portable multi-parameter collection device, operation data collection can be carried out in a most economical and convenient mode under the conditions that other hardware equipment is not added and an online diagnosis system is not installed.

Description

technical field [0001] The invention belongs to the field of data acquisition of wind turbines, and in particular relates to a data acquisition method of wind turbines based on a multi-parameter acquisition device. Background technique [0002] Wind turbine equipment includes related disciplines and majors such as machinery, electricity, electricity, industrial control, materials, aerodynamics, etc. At the same time, wind turbines have complex structures, frequent load changes, and harsh operating environments. Accompanied by fog and other environments. Therefore, the operation and maintenance of wind turbine equipment is a systematic and complex project. Due to the location and working environment of wind turbines, inspection and maintenance are difficult and costly. Therefore, how to monitor equipment, give early warning of abnormalities, and prevent problems before they happen becomes the focus of wind power equipment operation and maintenance. At present, wind turbine ...

Problems solved by technology

[0003] For the first method, the most important purpose of the SCADA system is to monitor the operation of the equipment and ensure the safe operation of the wind turbine unit. Once the equipment fails, most of the wind turbines in service only push some alarm information, and cannot provide specific equipment failure information. And through The data provided by SCADA cannot be analyzed to accurately locate the fault and the cause; for the second method, on the one hand, it is to monitor a type of data such as monitoring vibration data, or to detect a certain device such as a blade monitoring system. On the other hand, it needs to be connected after data collection The computer uploads the data and then analyzes it, but it is impossible to judge whether the collected data is "effective", and the efficiency of the entire data collection method is relatively low; as for the third method, the current wind power equipment monitoring is mainly through various third-party monitoring equipment and The system monitors and analyzes the fan equipment, but this requires the installation of relevant acquisition devices, sensors and other equipment on the fan. Although it is online acquisition, it needs to occupy the limited network bandwidth of the wind field on the one hand, and on the other hand, this method requires Each fan needs to install a set of equipment, which is expensive

At present, many wind turbines in service were built many years ago. During the construction, redundant network lines and cabin WiFi interface functions were reserved. There is no rich network and other hardware conditions
