The invention discloses a wind power generator variable-pitch battery charging system with an online monitor function. The system comprises a charging module, a temperature detection module, an internal resistance detection module, a processing module and an alarm module. The charging module is connected with a battery and used for converting alternating currents through power conversion to charge the battery. The temperature detection module is connected with the battery and used for detecting temperature of the battery. The internal resistance detection module is connected with the charging module and used for detecting the internal resistance of the battery after charging is completed. The processing module is respectively connected with the charging module, the temperature detection module and the internal resistance detection module. The alarm module is connected with the processing module and used for generating alarm signals when the battery is abnormal. Through the wind power generator variable-pitch battery charging system, the abnormal state of the battery can be timely monitored at the same time in the charging process, and therefore the situation that a pitch of a wind power generator cannot be normally unfolded when the battery breaks down can be avoided.
Description
technical field [0001] The invention relates to the technical field of wind power generators, in particular to a wind power generator pitch battery charging system with an online monitoring function. Background technique [0002] As non-renewable energy is facing the dilemma of depletion worldwide, in order to meet the needs of industrial production and human life, people's attention and utilization of renewable resources such as solar energy, wind power, and water power have been increasing day by day. Among them, wind power generation is a relatively mature energy development technology, which is widely popularized and applied especially in plateau and coastal areas. [0003] At present, the backup power supply of the wind turbine pitch system mostly uses lead-acid battery packs. Since the lead-acid battery is discharged at a current of 3C-5C when the pulp change system is collected, the lead-acid battery will be damaged to varying degrees after a period of use. If the ba...
