基于PLC的风光互补发电控制系统设计

基于PLC对风光互补发电系统的控制系统进行了设计，依据最大功率点跟踪控制理论（MPPT）分别对风力发电和光伏发电的控制系统进行了设计，实现最大限度的利用风能发电和太阳能发电的互补性能，提高系统的运行效率，增加系统的输出功率。试验结果表明该控制系统基本实现光伏发电和风力发电的最大功率点跟踪控制，同时满足蓄电池充电及过充、过放保护的要求，为风光互补发电系统的进一步应用提供理论参考。

Design of Wind-solar Hybrid Power Generation Control System Based on PLC

This paper designs the scenery complementary power generation control system based on PLC, and according to maximum power point tracking （MPPT） control theory, the control system of wind power and photovoltaic power generation system are designed respectively. The system realizes the use of wind power and solar power; the complementary capability has maximized exertion; the system efficiency has a great increase; and the output power reaches a high value. The experiment results show that the design of wind-solar hybrid power control system can realize the maximum power point of photovohaic power and wind power tracking control, satisfy the battery segmented charging and overcharge, overdischarge protection requirements, and provide theoretical reference for further application.
