Abstract

The invention provides a wind power converter, a fan conversion system and a fault processing method thereof. The method comprises the steps that whether a wind power converter breaks down or not is judged, and if so, the type of the fault is determined; if the type is a general fault, a fault notification is sent to a fan master control system of a wind generating set in a fan converter system, so that the wind generating set enters a shutdown mode; and after a preset wind generating set shutdown condition is met, the wind power converter is controlled to be shut down. Namely, when the wind power converter has a general fault, the fault notification can be sent to the fan main control system, so that the wind generating set enters a shutdown mode, enough time is reserved for the wind generating set, the wind generating set can be ensured to be stably shut down, and the impact on a fan transmission chain caused by an existing rapid load reduction shutdown mode is eliminated. The service life of a fan transmission chain is guaranteed, and the safe operation coefficient of the wind generating set is improved.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a wind power converter, a fan converter system and a fault processing method thereof. Background technique [0002] With the continuous development of wind power generation technology, wind power converters have also been widely used. According to the data survey, the installed capacity of wind power in my country is increasing year by year, which provides a strong impetus for the development of my country's wind power converter industry. [0003] At present, after any failure of wind power converter, such as serious failure or general failure, it will first notify its main controller through the fault dry node and communication signal, and then stop after a certain delay; however, wind power converter This method of rapid load reduction and shutdown will have an impact on the fan drive chain, which greatly affects the service life of the fan drive chain.
