Abstract

The invention discloses a fuzzy expert system-based fan safety chain fault analysis method and system. The method comprises the steps of collecting all operation data of safe operation of a wind driven generator; performing fault analysis on the operation data by using a fuzzy expert system; and if a the set has a fault in operation, performing emergency shutdown, and making the set offline. The fault analysis is performed on the safe operation data of the wind generating set by utilizing the fuzzy expert system to determine a fault occurrence type, and with the combination of historical data in a certain time period, the fault analysis accuracy is improved, and the fault maintenance time is shortened; and the system further has a data display function, so that a worker can conveniently check the operation state at any time.

Description

technical field

[0001] The present invention relates to the technical field of fault analysis of wind power generators, in particular to a method and system for fault analysis of wind turbine safety chains based on a fuzzy expert system. Background technique

[0002] Wind energy is the kinetic energy generated by the movement of large volumes of air over the Earth's surface. Due to the different temperature changes on the ground and the different water vapor content in the air after being irradiated by the sun, the air pressure in different places is different, and the high-pressure air flows to the low-pressure area in the horizontal direction, that is, the wind is formed. Wind energy resources are determined by the wind energy density and the annual cumulative hours of available wind energy. The World Meteorological Organization estimates that the global wind energy is about 2.74Γ—109MW, of which the available wind energy is 2Γ—107MW, which is 10 times larger than the total...
