The invention discloses a method and a device for collecting and analyzing data of wind generating set. The method includes the steps of A, acquiring data by communicating with a master control PLC (programmable logic controller) of the wind generating set, acquiring high-frequency data and low-frequency data by multithreading, and storing; and B, analyzing the acquired and stored data. The device comprises a data acquisition module, a data storage module and a data analyzing module. The data acquisition module is connected with the master control PLC of the wind generating set through a communication module and comprises a high-frequency data acquisition module and a low-frequency data acquisition module. The high-frequency data acquisition module and the low-frequency data acquisition module are connected with the data storage module which is connected with the data analyzing module. By the aid of the multithreading manner, instantaneity and integrity of data acquisition of the wind generating set are achieved, implementing is convenient, and cost is lowered.
Description
technical field [0001] The invention relates to the field of wind power generation, in particular to a method and device for collecting and analyzing data of a wind power generating set. Background technique [0002] In recent years, with the vigorous promotion of clean energy in the world, the wind power industry has developed rapidly, and the installed capacity of wind farms has increased year by year. The proportion of wind power is increasing, and it has gradually become a conventional energy source. The operation data of the wind turbine has become one of the key factors for the stability of the operation of the wind turbine, and the real-time and reliability of the operation data of the wind turbine are particularly important. [0003] The operating data of wind turbines can provide valuable support for wind turbine operation status monitoring, fault diagnosis and control optimization. Traditional OPCServer technology has two disadvantages: [0004] 1) Cost issues. ...
