针对电压暂降问题，提出了一种采用飞轮储能矩阵变换器的串联功率调节系统。先前的研究强调了提供足够的能量存储的重要性，以补偿弱系统中长时间的深电压跌落。由于选择飞轮作为首选储能设备，该解决方案利用单个ac/ac功率转换器作为电网接口，而不是更传统的ac/dc/ac转换器，从而提高了功率密度和系统可靠性。本文建立了包括双同步参考系中分别与飞轮机和电网耦合的矩阵变换器在内的整个系统的动力学模型。利用该动态模型设计了一个将电压暂降和空转状态下的负载电压补偿和储能管理功能无缝集成的矢量控制系统。给出了数值模拟结果和实验室规模硬件样机的实验结果来验证系统的性能。
A new series power conditioning system using a matrix converter with flywheel energy storage is proposed to cope with voltage sag problem. Previous studies have highlighted the importance of providing adequate energy storage in order to compensate for deep voltage sags of long durations in weak systems. With the choice of flywheel as a preferred energy storage device, the proposed solution utilizes a single ac/ac power converter for the grid interface as opposed to a more conventional ac/dc/ac converter, leading to higher power density and increased system reliability. The paper develops the dynamic model for the complete system including the matrix converter in dual synchronous reference frames coupled to the flywheel- machine and the grid, respectively. The dynamic model is used to design a vector control system that seamless integrates functions of compensating load voltage and managing energy storage during voltage sag and idling modes. The numerical simulation results and experimental results from a laboratory-scale hardware prototype are presented to verify system performance.
