Emergency control method with failure of anemorumbometer of wind generating set

Abstract

The invention discloses an emergency control method with failure of an anemorumbometer of a wind generating set. The emergency control method comprises the following steps of: (1), taking all units in a wind field as a centre, and forming a small network through an SCADA (Supervisory Control and Data Acquisition) system of the wind field and three units closest to the position of the SCADA system; (2), when the units are operated normally, feeding collected wind speed and wind direction signals back to a central controller through the SCADA system, and displaying various real-time information in real time; (3), when the anemorumbometer of the units is failed, reporting to the central controller at first, carrying out heterochromous display at an obvious position by the central controller, and giving an alarm to monitoring personnel; and (4), meanwhile, starting emergency control programs at corresponding functional positions in a fan control program, applying for reading wind speed / direction information from the SCADA system by a fan controller, if application is not successful, stopping; if the application is passed, sending instructions to the units according to data read in the SCADA system, and maintaining operation of the units till maintainers maintain a fan to exclude faults.

Description

technical field [0001] The invention relates to a control method, in particular to an emergency control method when an anemometer of a wind power generating set fails. Background technique [0002] Due to the high-altitude operation of wind turbines outdoors, and the anemometer is outside the cabin cover of the unit, its operating environment is very complicated: vibration, dust, exposure to the sun, freezing, rain and other extreme conditions; After years of salt spray corrosion, the probability of failure of the anemometer wind vane is relatively high. Usually, wind turbines are designed with two wind speeds and one wind direction. This design mainly solves the problem of unit shutdown caused by the anemometer, but once the wind vane fails, the fan will immediately shut down and cannot be started before the fault is eliminated, reducing the unit availability and economic benefits. [0003] When the anemometer of the unit fails and the wind speed is higher than the cut-ou...

Problems solved by technology

This design mainly solves the problem of shutting down the unit caused by the anemometer, but once the wind vane fails, the fan will stop immediately and cannot be started before the fault is eliminated, which reduces the availability and economic benefits of the unit

[0003] When the anemometer of the unit fails and the wind speed is higher than the cut-out wind speed of the unit, the unit cannot choose the stop position, resulting in a high risk factor for the unit
