摘要
提出了基于复杂可编程逻辑器件CPLD(Complex Programmable Logic Device)的暂态保护AD(Analog-to-Digital)模块。该模块无需主控制器的干涉,采集时间几乎只取决于AD转换器的时间,具有采样速度快、智能化、可靠性高、价格符合工程实际等一系列优点,同时保持与保护主控制器有良好的接口,可方便地嵌入到微机保护装置中,具有较强的工程实际应用价值。
It’ s proposed transient protection AD modules based on CPLD. This module is without interfering with the main controller, the acquisition time depends almost exclusively on time AD converter with sampling speed, which is with high intelligence, reliability, price in line with engineering a series of advantages, while maintaining and protecting the main control module has a good interface, which can be easily embedded into microprocessor-based protection device,with a strong practical value engineering.
