摘要
随着变电站综合自动化程度的提高,微机保护产品得到大量的应用。为了提高逻辑功能的适用性,提出了可编程逻辑的概念。用可编程逻辑来实现微机保护的新方法,具有简单、灵活、可靠、稳定等诸多优点,可以灵活地实现监控、保护和故障隔离等功能。
As the advancing in substation automation, microcomputer-based protection products are widely used. To improve the applicability of the logic functions, programmable logic concepts are presented. Using the programmable logic to realize the microcomputer-based protection has many advantages such as simple, flexible, reliable and stable, etc.. It also has many functions including monitoring, protection and fault isolation, etc., which significantly improves performances of substation automation systems.
