摘要
海洋能源是新能源中不可或缺的一种。由于海水的能量密度远远高于风能和太阳能,因此潮流发电在新能源领域一直是研究的新方向。潮流发电如何将产生的电能进行最大能量捕获,以及保持发电机处于最佳运行状态上,都是目前研究的重点。本文在潮流发电方向中,自主研制了一套潮流发电机组,为实验室模拟潮流以及实际海域发电提供良好的发电单元,并进一步设计出与之相配套的最大功率控制系统。该系统采用可应用于潮流发电的改进型最大功率跟踪(MPPT)控制算法;以及多电池均衡充电策略,即阶梯择优电池切换控制策略,保证潮流系统持续运行在最大功率。该控制系统在实际海域已进行实验和控制算法验证,为进一步探索潮流发电有深远的影响。
Marine energy is an indispensable source of new energy.Due to the energy density of seawater is much higher than that of wind energy and solar energy,it is particularly important in new energy power generation.How current power generation captures the maximum energy produced by the power generation and maintains the generator in its best operating condition are the focus of current research.This article independently develops a set of tidal power generating units in the tidal power generation direction to provide a good power generation unit for the laboratory simulation of tidal currents and actual sea power generation.And further design a matching maximum power control system that uses an improved MPPT control algorithm that can be applied to power flow generation;And multi-battery equalization charging strategy,which is a step-by-step battery switching control strategy to ensure that the power flow system continues to operate at maximum power.The control system has been verified by experiments and control algorithms in actual sea areas,which has far-reaching implications for further exploration of power generation.
