Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] like figure 1 As shown, the real-time processing method of wind turbine scada data based on flow calculation of the present invention comprises the following steps,

[0034] Step (A), receiving fan unit scada data, the process is as follows:

[0035] (A1) The operating data of the fan unit is stored in the distributed message queue kafaka through the collector;

[0036] (A2) Create different message topics according to the scada systems of different manufacturers, and subscribe to each topic message through the stream computing engine storm program, so as to obtain the scada real-time data of the scada system;

[0037] (A3) Place the obtained scada real-time data into the complex event processing engine esper;

[0038] Step (B), remove duplicate data: analyze the section data of scada real-time data of each fan unit per second, and deduplicate the section dat...

Abstract

The invention discloses a real-time processing method for wind turbine unit scada data based on stream computing. The method includes the following steps that A, the wind turbine unit scada data is received; B, repeated data is removed; C, the data is subjected to standardized processing; D, the operating state of the data is analyzed; E, the data is saved; F, the operating state of a wind turbine unit is diagnosed, wherein diagnosis is carried out when the operating state of the wind turbine unit breaks down according to the saved data. The real-time processing method for the wind turbine unit scada data based on stream computing is used for processing wind power scada real-time data, the processing performance is high, the expandability is high, the processing mode is flexible, the coding quantity is low, the new method is provided for wind power scada real-time data processing, and good application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of wind power data processing, in particular to a method for real-time processing of scada data of wind turbines based on flow calculation. Background technique [0002] Wind turbine scada (Supervisory Control And Data Acquisition) data collection frequency is relatively high, mostly once a second, and there are many collection points. One wind turbine will involve 1000-2000 measurement points. Therefore, one wind turbine will generate 200MB a day Data, a large-scale wind field has about 200 wind turbines, and a wind field will generate 300,000 measurement point data per second. [0003] At present, most of the scada data of wind turbines are processed by the scada system of each wind turbine manufacturer. With the demand of lean management, it is necessary to build a unified scada data processing system in order to uniformly access and process the scada data of wind turbines in the entire wind farm. At the...
