交直流混合微电网的规划设计

摘要

由于交直流混合微电网可以减少多重变换器运行所产生的损耗、谐波电流，同时能够提高系统的经济性、可靠性，所以现在已成为当今微电网的主要发展方向。笔者将从电压等级、接地方式、母线结构和网络拓扑等角度，探讨交直流混合微电网的规划设计，以供有意对交直流混合微电网进行深入研究的专家学者参考。%Due to micro AC/DC hybrid power grid can reduce multiple converter loss, harmonic current generated by the operation, at the same time can improve the efficiency of system, the reliability, so now it is the main direction of micro grid today. Grounding method, the author will from voltage grade, bus structure and network topology of micro AC/DC hybrid power grid planning and design were discussed, for the intention to conduct the thorough research to the micro AC/DC hybrid power grid in the experts and scholars to provide the reference.
