Abstract

The invention provides a fault positioning method and device of a wind power generator set. The method comprises the following steps that an ant colony algorithm topological structure is generated according to an electrical topological structure and a signal incidence relation of a system; an information element size of each path is determined according to the number of times of signal hopping ofeach path in the ant colony algorithm topology structure in a current detection period; and if it is determined that the fault occurs in the current detection period, the path corresponding to the maximum information element is the path with the fault, and a part, where the signal hopping occurs, in the path corresponding to the maximum information element is determined as a fault part. Accordingto the method and device, due to the fact that the ant colony algorithm is adopted for fault positioning, so that automatic positioning is achieved by a machine, manual checking is not needed, and manual analysis processes are reduced; and fault positioning can be carried out quickly, the utilization rate of the wind power generator set is improved, and the loss of power generation amount is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wind power generation, and in particular to a fault location method and device for a wind power generating set. Background technique [0002] A wind turbine is a device that converts wind energy into electrical energy. Due to the high integration of aerodynamics, structural mechanics, electrical machinery, material science, power electronics technology, power system analysis technology, relay protection technology, automatic control technology and modern communication technology, the wind turbine is a complex energy conversion system. Therefore, when the same fault occurs in the wind turbine, it may be caused by different reasons. For example, for the "three-axis angle inconsistency" fault of the pitch control system, the cause of the fault may be the fault of the encoder itself, the fault of the encoder power supply, or the fault of the pitch control system or the fault of the driv...
