摘要
针对低压配电网无功补偿问题,提出一种基于超声导波技术的创新解决方案.该方法利用超声导波在低压线路中的传输特性,实现对线路无功功率的实时监测与动态补偿.详细阐述超声波信号生成、超声波与线路耦合以及实时监测与控制等关键技术的实现原理.通过实验验证,在补偿电压为300 V、频率为1.2 MHz时,线路功率因数从 0.75 提升至 0.98,无功功率降低86.7%,同时电压总畸变率控制在 5%以内.研究结果表明,该方法能够有效提高低压终端线路的供电质量,为解决配电网末端无功问题提供新的技术路线.
Abstract
This article talks about a new way to fix power issues in low-voltage grids using sound waves.It uses sound waves to watch and adjust extra power in the wires.The text explains how to make sound waves,connect them to wires,and monitor everything.The experimental results show that when the compensation voltage is 300 V and the frequency is 1.2 MHz,the line power factor is increased from 0.75 to 0.98,the reactive power is reduced by 86.7%,and the total voltage distortion rate is controlled within 5%.This helps make electricity better at the end of power lines and gives a new fix for power issues in grids.
