With the unprecedented development of new energy technology£¬the wind power technology is brought into a brand-new situation£®Using Lead-acid battery to store electric energy, it is an important security of the safe operation of the wind turbine. Locating in the generator hub, it can provide backup power supply for generator. This smart charger, combined with the control system of wind turbine, will charge the battery automatically.
Based on the demand of actual enterprise product, a smart charger that specializes in Lead-acid battery of wind generator hub is developed and supports the control system of wind turbine. Some ralated work are performed, including the hardware circuit, control program, testing and validation.
This thesis mainly elaborates the software and hardware design of ARM board that controls the charger.
Switch power technology is applied to the charger, with running three-gradation charge intelligently based on 32-bits ARM kernel controller. A STM32F103RB, produced by STMicroelectronics, is adopted as controller, which samples the voltage, current and temperature of the battery and the switch power, and analyzes how to control three-gradation charge. Meanwhile, temperature compensation for charging voltage and current, safety monitoring, serial communication between the charger and peripheral equipment are operating. The charger is all-intelligent that detects the power and temperature and protects automatically, diagnoses the problem by itself and transforms to the acquisition equipment of the generator. These main parameter controlling the charger are reconfigurable online, thus improving greatly the compatibility with different wind turbine control system and lead-acid battery, but also enhancing the adaptation to various natural environment.
This thesis presents an ARM control board and implements the monitoring, alarming, temperature compensation, PC communication and parameter configuration. The result shows that all indexes meet requirements of the product.
