Problems solved by technology
Most of the existing wind turbines rely on manual methods to monitor the operation performance of wind turbines in real time, and the number of wind farms ranges from dozens to hundreds, especially a regional enterprise monitors thousands of wind turbines , relying only on manual methods, which is not only difficult to achieve, but also costly
In recent years, many scholars have proposed to monitor the operation performance of wind turbines by adding sensor measuring points on the unit, but in practical applications, there are indeed inaccurate positioning of monitoring points, and the installation of sensors increases investment costs, reliability and practicability. Inferior disadvantages

Embodiment Construction
[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] like figure 1 As shown, a method for monitoring the power characteristics of a regional wind farm unit designed by the present invention is used in the actual application process to perform horizontal comparative monitoring of the power characteristics of the same area and the same type of wind turbines in the regional wind farm, including the following steps:
[0029] Step 01. Statistically obtain the measured wind speed records in the specified area of the regional wind farm within the current time period, the measured wind power records of the same type of wind turbines in the area, and the corresponding relationship between them; among them, in order to improve the data In the process of statistically obtaining the measured wind speed records in the specified area of the regional wind farm within the curre...

The invention relates to a method for monitoring power characteristics of units of regional wind farms. Existing actually measured data of the regional wind farms are used, the method for transversely monitoring the power characteristics of the units of a regional wind farm group is provided, the power characteristics of the wind generation units are automatically monitored in real time, a real-time alarm can be given to the units with performance being reduced to a certain extent, operation and inspection workers are reminded to take measures, the performance of the wind generation units can be restored timely, the wind generation units are kept in a normal running status, and therefore the generating capacity of the wind farms is enhanced.
Description
technical field [0001] The invention relates to a method for monitoring the power characteristics of a regional wind farm unit. Background technique [0002] As energy and environmental issues are getting more and more attention today, wind energy, as a clean and renewable energy, has developed rapidly in many countries. my country also regards the development of wind energy as a key point of its national energy strategy. With the continuous growth of domestic wind power development scale, the installed capacity of wind power enterprises has also increased, and the number of installed units has also increased. The performance will also decline accordingly, and many other uncertain factors may lead to the decline in the performance of the wind turbines. How can the wind power operating enterprise monitor these units with degraded performance in a timely manner, analyze the reasons for the performance degradation, and take timely corrective measures to restore the units. It is ...
