摘要
为解决偏远地区供水供电问题,根据不同的容量和用途开发2套风光互补提水系统及其对应的控制器。针对有蓄电储能的低压小功率系统,研究并制定简单高效的控制方案和基于蓄电池荷电状态的运行模式。针对无蓄电储能的高压大功率系统,提出以风电、光伏与水泵的协调控制方法保证风能与太阳能的利用率和系统的稳定性。对控制器产品样机和系统运行特性进行实验验证。
In order to provide a solution of water and electricity supply applicable to remote areas,two sets of hybrid photovoltaic(PV)-wind pumping systems and corresponding controllers in terms of different capacities and applications are designed and developed in this paper.Regarding a low-voltage and low-power system with batteries,a simple and highly efficient control scheme and operating modes according to battery state-of-charge are studied and determined.Accordingly a high-voltage and high-power system with no battery,a coordinated control strategy pertinent to wind power,PV and pump is proposed,which can guarantee the availability of wind power and solar energy whilst keeping the stability of the whole system.The prototype of controller and the system operating characteristics are verified by experiments.
