Problems solved by technology
When the battery is overcharged or overdischarged, it will affect the life of the battery. Therefore, how to control the charge and discharge of the battery for energy storage to improve the utilization rate and service life of the battery is an urgent problem to be solved.
Battery photovoltaic charge-discharge controllers have already been released. Most photovoltaic charge-discharge controller products use pulse voltage charging to charge the battery. The controller’s analysis and design of battery terminal voltage indicators are slightly insufficient.

The invention relates to a wind power storage operation control method. The method is mainly technically characterized by comprising the following steps: 1, a wind power storage operation controller is connected into a wind power generation system; 2, a CPU unit samples external voltage of a battery and temperature of the battery via a divided voltage acquisition module and a temperature acquisition module, outputs PWM signals and carries out charging control on the battery via a charging power switch circuit; and 3, the CPU unit samples external voltage of the battery and temperature of the battery via the divided voltage acquisition module and the temperature acquisition module, outputs PWM signals and carries out discharging control on the battery via a discharging power switch circuit. according to the method of the invention, the battery temperature and external voltage analog are sampled in real time, and the PWM signals are outputted to control the power switch to charge and discharge the battery; functions of fault removing, abnormal information alarm and the like during the operation process can be realized, the battery can be ensured not to over charge or over discharge, quick charging and discharging can be realized, and the charging and discharging efficiency and the service life of the battery can be prolonged.
Description
technical field [0001] The invention belongs to the technical field of wind power energy storage operation control, in particular to a wind power energy storage operation control method. Background technique [0002] With the gradual exhaustion of conventional energy sources and the increasing environmental pollution, countries around the world are paying more and more attention to distributed power generation technology, which has led to continuous innovation of distributed power generation technology. At present, the types of distributed power sources mainly include micro-gas turbines, solar photovoltaic cells, wind generators, batteries, and flywheels. As an important form of distributed power generation, the microgrid is usually a small power generation and distribution system composed of distributed power sources, energy storage devices, energy converters, related loads, monitoring systems, protection systems, and power transmission equipment. Autonomous systems capabl...
