软交换技术在百万级水电站的应用与实践

Application and practice of soft switching technology in large hydropower station

当前在电力系统行政语音网内广泛使用的程控交换系统,由于该技术较为老旧及使用时间不断增加,给运维人员的运维消缺带来越来越多的麻烦。天生桥水力发电总厂在对语音交换系统的改造中采用了软交换系统,通过对软交换系统的运维消缺情况进行跟踪,发现软交换系统可以很好的解决程控交换系统产生的众多问题。因此,软交换技术在电力通信系统中有着很好的推广应用前景。

SPC（ Statistical Process Control） switching system was widely used in current power systems in administrative voice network. Due to the old technology and the increasing use of time,it brought more and more troubles for maintenance staff with equipment maintenance and eliminate defect. The soft switch system was selected in the transformation of voice exchange system by the CSG Power Generation Company Tianshengqiao Hydropower Station. By tracking the equipment maintenance and eliminating defect,the company found that the soft switch system can solve many problems of SPC switching system. Therefore,soft switching technology had a good application prospect in power communication system.
