Traction converter fault early warning model, modeling method, early warning method and system

Abstract

The invention discloses a traction converter fault early warning model, a modeling method, an early warning method and a system. The modeling method comprises the following steps of 1, collecting multiple groups of modeling data of a traction converter in M different operation states, wherein each group of modeling data comprises a plurality of groups of operation parameter values and operation state data corresponding to the next time point of the acquisition time point of the operation parameter values, the M different operation states comprise M fault states of the traction converter, or the M different operation states comprise M-1 fault states and normal states of the traction converter, and 2, taking the operation parameter value in the modeling data as input, taking the operation state data as output, and learning to obtain a traction converter fault early warning model. According to the method, the fault state of the traction converter can be predicted in the running process of the train, early warning is carried out before the fault of the traction converter occurs, and therefore enough stress protection time is given, and the running safety of the train is better guaranteed.

Description

technical field [0001] The invention belongs to the field of traction failure analysis of rail transit vehicles, and in particular relates to a traction converter failure early warning model, modeling method, early warning method and system. Background technique [0002] With the development of high-speed train technology and the construction of a large number of high-speed railways, the speed of trains is getting faster and faster, and the load of trains is also increasing, and the probability of failure of parts on trains is also increasing. Among the many system equipment of the train, the traction converter provides electric energy for the train traction and auxiliary power consumption, and is a very important part of the train. The traction converter is composed of many components, and the integration degree between the components is high. When a component fails, it is likely to cause a large chain reaction, and in severe cases, it may cause machine failure during train...
