摘要

本文考虑供电系统的连续性，提出了风光互补供电系统设备容量设计，讨论了离网型光伏风能发电系统的构成及特点，以及蓄电池和控制器在系统中的重要作用。通过理论研究结合工程实际，对一种风光工程应用的光伏电池方阵、风机、控制器、蓄电池组和离网型逆变器的容量计算及选择进行了分析。本系统的应用，不但解决了发电系统存在的问题，还保障了风光互补供电系统的连续性、稳定性和可靠性，最终使其可以满足广大用电客户的需求。%In view of the continuity of the power supply system, the capacity design of wind/PV hybrid power system equipment was proposed. The construction and characteristics of off-grid wind and solar power generation system were discussed in this paper. The roles of controller and battery in the system were considered. By theoretical research and engineering practice, the capacity calculation and selection of a wind/PV hybrid power system with photovoltaic cell matrix, wind generator, controllers, batteries, and off-grid inverter were analyzed. The implementation of this system not only can solve the common problems of power system, but also can guarantee the continuity, stability and reliability of the wind and solar hybrid power system, thus meeting the requirements of general electricity customers ultimately.
