Wind turbine generator storage battery detector

Abstract

A wind turbine generator storage battery detector comprises an access selection module, a prepositive amplification band-pass filtering module, a correlated operation module, an integrator module, a DC amplification module, a single-chip microcomputer system module, an AC constant current signal generation circuit module, a square wave conversion circuit, a sampling circuit, a keyboard module, a display module and a serial port module. The wind turbine generator storage battery detector provided by the present invention can test the performances of a single set of multiple sets of lead-acid storage batteries, can measure the end voltages, the internal resistance values and the environment temperatures of the storage batteries accurately, and can determine the residual capacity and the performances of the storage batteries accurately, thereby evaluating the overall characteristics of the storage batteries. The detector of the present invention does not need to disconnect the two poles of the storage batteries at detection, does not need to charge and discharge the storage batteries, does not need to disconnect the loads of the storage batteries, and is simple in steps of a used method, many in measurement items and high in result precision.

Description

technical field [0001] The invention belongs to the technical field of accumulators, and in particular relates to an intelligent accumulator detector for a wind power group. Background technique [0002] Lead-acid batteries are usually used in wind turbines. Once the lead-acid batteries are aged or damaged, it will bring serious safety hazards to the entire wind turbine system. By regularly testing the remaining capacity and performance of lead-acid batteries, potential safety hazards can be discovered as early as possible, thereby effectively avoiding accidents. Existing battery testers often can only detect voltage, electricity, etc., but cannot detect information such as internal resistance and remaining capacity of the battery, and cannot judge the performance status of the battery. In particular, it is often necessary to disconnect the battery output during measurement, or to charge and discharge the battery, which affects the normal operation of the back-end equipment...
