Embodiment Construction

[0036] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0037] like figure 1 As shown, an automatic fault diagnosis system triggered by a fault model disclosed in the present invention includes: a sensor, multiple fault models, a fault classifier and a fault level evaluation module; wherein each fault model corresponds to a group of component types and fault types ;

[0038] The sensor is used to obtain the vibration acceleration signal of each component of the equipment to be detected;

[0039] Fault model, which stores the corresponding component type, component fault chara...

Abstract

An automatic fault diagnosis system triggered by a fault model disclosed in the present invention includes: a sensor for obtaining vibration acceleration signals of each component of the equipment to be detected; a fault model for storing the corresponding component type, component fault characteristic frequency and corresponding component type and the component fault code of the component fault characteristic frequency, when there is a frequency component matching the component fault characteristic frequency in the vibration acceleration signal, the component fault code is sent to the fault classifier and the start signal is sent to the fault level evaluation module; the fault classifier, for the component The fault code is classified and the corresponding fault type information is searched, and the fault type information is output as the fault type diagnosis result; the fault level evaluation module calculates the vibration intensity according to the vibration acceleration signal after receiving the start signal, and evaluates the fault level to obtain the fault level diagnosis result . The invention can improve the fault diagnosis efficiency of wind turbines and other equipment.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis. More specifically, it relates to an automatic fault diagnosis system triggered based on a fault model, which is especially suitable for fault diagnosis of wind power generating sets. Background technique [0002] The unit power generation cost of wind power is basically close to the cost of thermal power generation. It is currently the most commercially valuable and most popular energy type among all renewable energy sources. [0003] Wind power generation is the key direction of the medium and long-term planning in the national energy field. The total installed capacity of wind turbines in my country has reached 74 million kilowatts, accounting for 7% of the total installed capacity of the power grid. The total installed capacity of wind power in the 13th Five-Year Plan will reach 150-200 million kilowatts; by 2050, the total installed capacity of wind power will reach about 17-20% of th...
