摘要: 针对新疆南疆偏远地区棉田灌溉用电需求受限问题,考虑充分利用当地良好的光照资源,设计了一种面向棉田灌溉的光-储联合供电系统。该系统主要由光伏发电单元、双向DC-DC变换器、变流环节及储能模块等构成,在设定系统参数的同时进行了系统控制策略设计,并利用Simulink仿真平台搭建了系统仿真模型。仿真结果表明,该系统不仅能够快速响应光伏功率跟踪、维持储能蓄电池充放电状态平稳,而且可以实现交流输出电压,符合棉田灌溉负荷的用电要求。

Abstract: In view of the limited demand of electricity for cotton field irrigation in remote areas of southern Xinjiang, considering the full use of local good light resources, a light-storage combined power supply system for cotton field irrigation was designed. The system was mainly composed of the photovoltaic power generation unit, bidirectional DC-DC converter, converter and energy storage module, etc. While setting the system parameters, the system control strategy was designed, and the system simulation model was built by using the Simulink simulation platform. The simulation results showed that the system could not only respond quickly to photovoltaic power tracking and maintain the stable charging and discharging status of energy storage batteries, but also meet the requirements of cotton field irrigation load with ac output voltage.

Key words: cotton field irrigation, combined optical-storage power supply, control strategy, Simulink simulation
