Virtual anemometer tower device of wind power plant power prediction system

Abstract

The invention discloses a virtual anemometer tower device of a wind power plant power prediction system, and relates to the technical field of wind power production and operation. The device comprisesa virtual anemometer tower device and a substation external network, the virtual anemometer tower device is connected to a wind power plant power prediction substation external network through a network cable, and the substation external network is connected with a substation internal network through forward isolation and reverse isolation; the ip of the substation external network and the ip ofthe virtual anemometer tower device are arranged to be in the same network segment, and normal communication is guaranteed. The problem that the anemometer tower cannot be installed in a wind field due to the terrain environment or the problem that fault data of an existing anemometer tower is interrupted is solved. By using the virtual anemometer tower device, the continuity of anemometer tower data can be ensured, and the real-time updating of the anemometer data and the reporting rate of an uploading power grid are ensured. Due to the application of the virtual anemometer tower device, thecontinuity and integrity of wind measurement data of a wind power plant are improved, data assessment caused by anemometer tower faults or communication problems is effectively avoided, and the overall efficiency of a power prediction system is improved.

Description

technical field [0001] The invention relates to the technical field of wind power production and operation, in particular to a virtual wind measuring tower device for a wind farm power prediction system. Background technique [0002] With the rapid growth of wind power installed capacity, problems such as grid integration become more and more prominent, and wind energy has unique characteristics of volatility, intermittency, and anti-peak regulation. affect the overall operation. Prediction of results through wind power forecasting can provide safety and reliability to the grid as well as the ability of the grid to accommodate wind. With the introduction of "two detailed rules" by the regional energy supervision bureaus, the assessment rules of each region have requirements for the reporting rate of power forecast data. If the data reporting rate does not meet the relevant requirements, the wind farm will be assessed. The reporting of wind tower data is also gradually incl...
