Abstract

The present invention provides a fault location method and device for a wind power generating set. The method includes: generating an ant colony algorithm topology structure according to the electrical topology structure and signal correlation of the system; The number of signal jumps in the path determines the pheromone size of each path; if it is determined that a fault occurs within the current detection cycle, determine the path corresponding to the largest pheromone as the path where the fault occurs, and determine the path corresponding to the largest pheromone. A component whose signal jumps is a faulty component. Due to the use of ant colony algorithm to locate the fault, it can be automatically located by the machine without manual investigation, which reduces the manual analysis process, and can quickly locate the fault, which improves the availability of wind turbines and reduces power generation. Loss.

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...
