Like the battery pack in the independent photovoltaic system, the same role is used, and the energy storage is no wind, and there is no sunlight.
In a scenery complementary power generation system, the controller mainly includes a wind power control system, a photovoltaic control system, and a battery charge and discharge controller. They are mainly based on the charging status of the battery to control the operational mode and opening of the wind turbine, solar cell power generation, thereby ensuring the normal power supply of the load and the safe operation of the various parts of the system.
The inverter is not marked in the system block diagram, which outputs the direct current obtained by the wind turbine output transform, and the solar battery array output and battery discharge converted into an alternating current required to load. The main circuit of the inverter is composed of high-power transistors, using a string pulse width modulation, strong anti-interference ability, and the three-phase load imbalance can reach 0-100%, and there is a strong overload and current limiting protection.
The role is also to prevent the battery from discharge through the solar cell when there is no sun.
Guancang Village, Dawang Village, Jiulong Town, Wangcang County, Guangyuan City leads to environmental pollution problems. On August 9, 2017, the masses reported to the Central Fifth Environmental Protection Supervision Group of Wang Cang County, Daxia Village, Yangcang, Dried Rattle, Purchase Problem. After investigation, the mass reporting problem is true. Beginning in January 2017, the masses have repeatedly reflected the issues to Guangyuan City, Wangcang County, and the relevant units of Wang Cang County and the responsible person fulfilled their duties, and the rectification is not in place. According to the research and decision of Wang Cang County Commission for Discipline Inspection, He Jiaqiang, Secretary of the Party Committee of Jiulong Town, Taoist Liang Zilong, Town, Jiulong Town; President of the People’s Congress of Jiulong Town, Gong Dan, County Agricultural Bureau, Zhou Kuilin, County Environmental Protection Bureau Environmental Monitoring Brigade Brigade, Liu Yingtao, criticized.
Common imported batteries include: Sanyo battery, Panasonic battery, LG battery, Samsung lithium battery.
The application of the wind turbine in the network environment requires the battery, and the total capacity of the battery pack is calculated as follows: total capacity = (total power power ¡Á 1.67 per day ¡Á 1.67) ¡Â The battery pack voltage. In practical applications, the voltage of the battery pack needs to be consistent with the rated output DC voltage of the wind turbine. The total power of the electric equipment is 800W, the electric power generator power is 1000W, the rated voltage is 48V, and the theoretical total capacity of the storage battery = (6 ¡Á 800 ¡Á 1.67) ¡Â 48 = 167ah. In the actual configuration, it should be slightly larger than the calculated value, because the battery should be completely discharged, thus selecting a 200AH48V battery, or a battery of 100AH24V is used in series. However, a larger battery should not be configured to prevent the battery due to a long time floating or full of life.
Battery configuration description:
1. The battery must be placed in a dry room temperature, placing the battery’s surrounded by spacious and ventilated, determines the total number of batteries in series, and then designed to place the battery and controller, the inverter holder.
2. Connect the battery in series, the specific method is: the positive electrode of the first battery picks up the negative electrode of the second battery, and is pushed.
3. Apply all the wiring headers to oil or other anti-corrosion materials, and install the fuse positive in the battery; in order to avoid electromagnetic interference, the connection wire between the battery and the controller should be shorter than 3 meters.
