摘要
为了达到提高光伏逆变器的容量和性能目的,采用并联型注入变换技术。根据逆变器结构以及光伏发电阵电流源输出的特点,选用工频隔离型光伏并网逆变器结构,并在仿真软件PSCAD中搭建光伏电池和逆变器模型,最后通过仿真与实验验证了理论的正确性和控制策略的可行性。
In order to improve the capacity and performance of photovoltaic inverter,the parallel injection transform technology was adopted.According to the inverter structure and output characteristics of PV generating array current source,the frequency-isolation type photovoltaic grid-connected inverter structure was selected,and photovoltaic cell and the inverter models were built in PSCAD simulation software.The correctness of the theory and feasibility of the control strategies were verified through simulation and experiments.
