Method and system for data collection and control of wind power plant device through front-end processor

Abstract

The invention provides a method for data collection and control of a wind power plant device through a front-end processor and a system for the data collection and the control of the wind power plant device through the front-end processor. The front-end processor is provided with a communication interface connected with a data processing server and provided with wind power plant device communication interfaces of various standards. A front-end data collecting system in the front-end processor comprises a data collecting module, a data internal conversion module, a data calculating and processing module and a data storage module. The data collection comprises the steps: real-time data of the wind power plant device are collected by the front-end processor and unified conversion and statistic analysis processing are conducted on the real-time data; the obtained data are stored and sent to the data processing server so as to be called by an upper-level system. The control comprises the steps: a control order is sent by the upper-level system, the received control order is converted by the front-end processor and sent to the corresponding wind power plant device, and the converted control order is read and conducted by the wind power plant device. The system for the data collection and the control of the wind power plant device through the front-end processor is stable in operation, timely and accurate in data conducting, professional in function, friendly in interface, and capable of achieving remote monitoring or centralized control of various wind turbine generators.

Description

technical field [0001] The invention relates to a data collection and control technology, in particular to a method and system for collecting data and controlling wind farm equipment through a front-end computer. Background technique [0002] The data acquisition system is the basis of the wind farm central control system and other systems, and is responsible for the functions of basic data acquisition and control command transmission. [0003] Data acquisition systems generally operate in harsh external environments such as large temperature changes, strong power surges, large electromagnetic interference, and large vibrations. In addition, due to the large differences in equipment on-site in wind farms, fans of different manufacturers, power substation equipment and Other equipment adopts different communication protocols, so the requirements for wind farm monitoring system are getting higher and higher, and higher requirements are put forward for the real-time and stabili...

AI Technical Summary

Problems solved by technology

[0004] At present, the data acquisition methods used by a large number of wind farm central control systems (substation SCADA systems) are hybrid centralized systems. The data acquisition system is integrated with the upper system without hierarchical processing. If new equipment needs to be connected Changes to the overall system are not conducive to extended development

[0005] Therefore, the existing data acquisition system still has inconvenience and defects in terms of stability, compatibility, and configuration flexibility, and needs to be further improved.
