摘要
随着电力系统中分布式发电及微电网技术的广泛应用,传统的储能变流器无法满足需求。针对储能变流器进行研究,获得一级拓扑变换双模式储能变流器的主电路拓扑结构,同时具备并网运行以及离网运行功能,确定了并网/离网模式转换策略及控制策略。以数字信号处理器(TMS320F2812DSP)作为核心控制芯片,研制了一台功率为20kW储能变流器样机。结果表明,该储能变流器动态响应快、充放电电流谐波小、并网/离网模式转换时间短,具有较好推广价值。
Traditional energy storage converter has been unable to meet demand with the development of distributed generation and micro-grid technology. This research focuses on energy storage converter development by achieving main circuit topological structure of dual-mode energy storage inverter with both in-grid and off-grid operation function and determining the in-grid/off-grid mode switching and control strategy. With digital signal processor （TMS320F2812 DSP） as the core control chip, a 20 kW energy storage converter prototype was developed. Results show the advantages of the energy storage converter, including quick dynamic response, small charge/discharge current harmonic, short in-grid/off-grid mode switching time, and therefore great promotion value.
