CPLD在高压微机保护装置中的应用研究

The Application of CPLD in the High-Voltage Digital Relay Protection Equipment

随着基于EDA技术的CPLD的快速发展,CPLD以其高速度、高可靠性等优点在变电站综合自动化系统中得到了广泛的应用。本文介绍了一种在高压微机保护装置中利用CPLD技术的方法,通过此方法使保护装置的PCB布线大为简化,抗干扰能力和实时性能都有了很大的提高。

With the development of Complex Programmable Logic Device （CPLD） based on the EDA technique, CPLD has been widely applied in the substation automation system. A detailed method of the using of CPLD in the digital, relay protection equipment is given. This scheme not only makes the layout of the PCB more simplified, but also improves the real-time performance and anti-jamming of the digital relay protection equipment.
