Wind turbine generator multimode adaptive control method and device, and computer storage medium

Abstract

The invention discloses a wind turbine generator multimode adaptive control method and device, and a computer storage medium. The wind turbine generator multimode adaptive control method comprises thesteps: S1, a digital prototype model of a wind turbine generator is built; S2, operating state data of the controlled wind turbine generator are collected in real time; S3, the collected operating state data are input into the digital prototype model to be compared, whether the controlled wind turbine generator is in a normal operating state or not is judged, and if not, the step S4 is shifted tobe executed; and S4, the control mode is determined according to a comparing result to control the controlled wind turbine generator to be adjusted to be in the normal operating state. The wind turbine generator multimode adaptive control device comprises a prototype model building module, a data collecting module, a state judgment module and a multimode adaptive control module. Multimode adaptive control over the wind turbine generator can be achieved, operating reliable stability of the wind turbine generator is improved, and the advantages of simple realizing method, low cost, high controlefficiency and precision and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of wind turbine control, in particular to a wind turbine multi-mode self-adaptive control method, device and computer storage medium. Background technique [0002] Various faults may occur during the operation of the wind turbine in the wind farm. At present, after the failure of the wind turbine, the location and cause of the fault are manually checked, and then the wind turbine is controlled to return to normal operation. Detecting the fault state before the wind turbine failure occurs will not only cause economic losses, but also affect the normal and stable operation of the wind turbine, and the wind turbine is in a period from the abnormal operation state to the alarm or fault when the fault occurs. A "sub-healthy state", if the abnormal point can be detected before the failure occurs and corresponding control corrections can be made, the load can be effectively reduced, unnecessary downtime maintenance...
