Embodiment 1

[0055] A method for reporting fault codes in a wind power generation control system, such as figure 1 As shown, the reporting method may include the following steps:

[0056] Step S11: activate the fault code;

[0057] Step S12: judging whether the fault code is a dominant fault code, wherein the dominant fault code corresponds to the shutdown fault of the wind turbine;

[0058] If it is judged to be yes, execute step S13: reset the shutdown fault corresponding to the dominant fault code;

[0059] If the shutdown fault is successfully reset, step S14 is executed: the dominant fault code is not reported, and the wind turbine is kept in normal operation;

[0060] If the shutdown fault reset is unsuccessful, step S15 is executed: the dominant fault code is reported.

[0061] In this embodiment, the fault codes may include explicit fault codes, recessive fault codes and derived fault codes. Wherein, the dominant fault code may correspond to the shutdown fault of the wind turbi...

Embodiment 2

[0088] The method for reporting fault codes in the wind power generation control system of this embodiment is a further improvement on the basis of Embodiment 1. In the case where the number of dominant fault codes is multiple, the reporting method may further include the following steps:

[0089] The dominant fault code is selectively reported according to the preset fault priority; wherein, for any first dominant fault code activated first and second dominant fault code activated later, if the second dominant fault code The fault priority of the code is not lower than the fault priority of the first dominant fault code and the shutdown fault reset corresponding to the first dominant fault code and the second dominant fault code is unsuccessful, then reporting the first dominant fault code and the second dominant fault code;

[0090] If the fault priority of the second dominant fault code is lower than the fault priority of the first dominant fault code and the shutdown corre...

Embodiment 3

[0103] A system for reporting fault codes in a wind power generation control system, see Figure 4 , the reporting system 1 may include:

[0104] an activation module 11 for activating the fault code;

[0105] The judgment module 12 is used for judging whether the fault code is a dominant fault code, wherein the dominant fault code corresponds to the shutdown fault of the wind turbine; if it is judged to be yes, the reset module 13 is called; 13 is used to reset the shutdown fault corresponding to the dominant fault code;

[0106] The fault code processing module 14, if the shutdown fault reset is successful, will not report the dominant fault code and keep the wind turbine running normally; if the shutdown fault reset is unsuccessful, report the obvious fault code. Sexual fault codes.

[0107] Further, the reporting system 1 may also include a recording module 15:

[0108] If the judgment module 12 judges it to be no, the recording module 15 records the fault type corresp...

Abstract

The invention discloses a reporting method and reporting system of fault codes in a wind power generation control system. The reporting method comprises the following steps of activating the fault codes; judging whether the fault codes are explicit fault codes or not, wherein the explicit fault codes correspond to shutdown failure of a wind generating set; if the fault codes are explicit fault codes, the shutdown failure corresponding to the explicit fault codes is reset; if the shutdown failure is reset successfully, the explicit fault codes are not reported, and normal running of the wind generating set is kept; if the shutdown failure resetting does not succeed, the explicit fault codes are reported; and according to the technical scheme, the shutdown frequency of the wind generating set is effectively reduced, and meanwhile, wear to a brake system due to frequent shutdown can be reduced.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a method and a reporting system for reporting fault codes in a wind power generation control system. Background technique [0002] Wind power generation is one of the energy-saving and environmentally friendly new energy power generation methods in recent years, which can convert renewable wind energy into electricity. The implementation of wind power generation is inseparable from the overall regulation of wind turbines, generator sets, communication modules and various monitoring modules by the wind power generation control system. When the wind power generation control system detects a fault, it will activate the fault code representing the fault, and can report the fault code to remind the staff to repair it in time. [0003] However, in the prior art, all activated fault codes are reported in full without processing, which will not only cause the wind turbine ...
