【摘要】：针对电力系统对可靠性、节约能源、智能化的要求,提出一种基于纳米复合磁性材料、具有内在磁状态自动调节能力的可控电抗器磁路设计方案。首先,分别从宏观及微观角度研究复合磁性材料的磁化模型,确定剩磁与矫顽力的关系并给出材料的制备工艺;其次,运用磁路磁阻理论分析方法,将制备的纳米复合磁性材料植入传统可控电抗器中,完成电抗器结构设计和电磁设计方案;最后,提出该电抗器的磁路设计方法并制备了一台220V/1k V?A/700m H样机,建立实验系统及其控制系统。仿真及实验结果表明,基于纳米复合磁性材料的可控电抗器仅依靠材料的剩磁即可实现连续、平滑的电感值调节,对电力线路能够进行快速无功功率补偿,节能效果显著。所设计的可控电抗器可以作为一种保障智能化电网安全运行的新型电力设备。
[Abstract]:In order to meet the requirements of reliability, energy saving and intelligence in power system, a magnetic circuit design scheme of controllable reactor based on nano-composite magnetic material with the ability of automatic adjustment of internal magnetic state is proposed. Firstly, the magnetization models of composite magnetic materials are studied from the macro and micro perspectives, the relationship between remanence and coercivity is determined and the preparation process is given. Secondly, the magnetic circuit magnetoresistive theory analysis method is used to implant the nanocomposite magnetic material into the traditional controllable reactor to complete the design of the reactor structure and electromagnetic design. Finally, the magnetic circuit design method of the reactor is presented, and a 220V/1k V?A/700m H prototype is prepared, and the experimental system and its control system are established. The simulation and experimental results show that the controllable reactor based on nano-composite magnetic material can realize continuous and smooth inductance adjustment only depending on the remanence of the material, and the power line can be compensated for reactive power quickly, and the energy saving effect is remarkable. The designed controllable reactor can be used as a new type of power equipment to ensure the safe operation of intelligent power grid.
