提高数字电力线载波机运行可靠性的研究

Research of Improving Reliability for Digital Power Line Carrier Operation

数字电力线载波机和模拟电力线载波机在实际应用中,哪种设备能更好的满足电力通信的要求是一个值得研究的问题,对该问题的争论从数字电力线载波机面市以来一致没有停息,2008年初南方电网遭受的特大冰灾更引来了一场数字电力线载波机的危机。文章试图对不具备或单纯依赖自动速率调整的数字电力线载波机的固有弱点进行分析,并针对如何提高数字电力线载波机的可靠性和设计上应采取的措施提出一些看法,希望能促进我国数字电力线载波机的技术进步。

In the practical application, the digital power line carrier machine and simulate power line carrier machine, what kind of device can better the meet the power communication requirements is worth to explore. Since the digital power line carrier coming onto the market, the debating of this issue on the consensus do not stop. However, the Southern Power Grid at the beginning of 2008 suffered serious ice storm has caused a crisis of the digital power line carrier. This article attempts to analyze the inherent weakness that simply relied on the automatic rate adjustment of the digital power line carrier machine, and puts forward some opinions that improve the reliability of digital power line carrier machine, it can promote our digital power line carrier of technological progress
