Problems solved by technology

Due to the harsh working environment of wind turbines (for example, field conditions, no-man’s land, etc.), when a fault that cannot be reset automatically occurs, personnel are required to go to the site to deal with it, which not only consumes a lot of manpower and material resources, but also loses power generation

Abstract

The invention provides a method and apparatus for monitoring a battery in an uninterruptible power supply. The method comprises: external power inputting to an uninterruptible power supply is stopped and a battery in the uninterruptible power supply provides power for a load; when the battery provides power for the load, a discharge coefficient of the battery and discharge time of the battery for releasing the stored electricity by a first predetermined percentage are detected; according to the discharge coefficient of the battery, one standard discharge curve is selected from a plurality of standard discharge curves of the battery; and the discharge time and the standard discharge curve are compared to determine whether the battery fails to work.

Description

technical field [0001] The present invention relates to the technical field of wind power generation, and more specifically, relates to a method and a device for monitoring a battery in an uninterruptible power supply of a wind power generating set. Background technique [0002] In view of the negative impact of fossil fuel consumption on the ecological environment, renewable energy has attracted much attention in recent years, and it will be the general trend to replace traditional energy with new clean energy. Due to the short construction period and high power generation efficiency of wind power generating units, they are more and more popular, so wind power has become the main force of new energy power generation in my country. [0003] The operating environment of wind turbines is different from other industrial environments. Due to the harsh working environment of wind turbines (for example, field conditions, no-man’s land, etc.), when a fault that cannot be reset aut...
