Intelligent Pole-mounted Dynamic Reactive Power Compensator Based on Synchronous Vacuum Switches

设计了一种新型智能型柱上机械投切电容器无功补偿设备。该设备首次将选相投切真空永磁断路器应用于户外柱上投切并联电容器。利用真空断路器开断能力强、分散性小、安全可靠的特点,实现了户外柱上无功补偿领域技术的突破。选用浮点DSP作为控制核心,对电容器组进行选相投切。动作时间自适应补偿,提高选相投切时间精度,抑制了电容器投切产生的过电压和涌流。相对于传统的户外无功补偿设备,此系统可靠性高,过电压和涌流小,损耗小,成本低,填补了国内户外无功补偿领域选相投切技术的空白。
