摘要
高压智能同步开关技术是有效抑制电力系统操作过电压和涌流以及全面提高电能质量的关键技术,而实现高压开关过零同步投切关键在于对三相电压过零点的精确检测。研究了三相电压过零的精确检测方法,设计所需的数字低通滤波器,在altera器件CYCLONEEP1C6中实现,并用Quartus5.0中嵌入式逻辑分析仪得到验证。
Intelligent synchronous high voltage switch can be utilized to minimize the switching overvohages and high inrush currents in power systems ,as well as to improve the overall power quality ,and that achieve the synchronized-closing of high voltage switch key to precision dectection of zero crossing point for three phase voltage. The detection precision of zero crossing point for three phase voltage was designed ,and designed by a low-pass digital filter, and implemented in ahera CYCLONE EP1C6,and verified by using quartus 5.0 embedded logic analyzer.
