In the smart-grid era, distribution power systems are undergoing a great deal of renovation. Utilities, more than ever before, are adopting technologies that aim primarily at enhancing the reliability of the power delivery systems in a safe and sustainable manner. In this paper, we analyze the reliability enhancements that distribution automation technologies bring to power distribution systems. We...
This paper describes hybrid-redundant design of monitoring systems with proprietary industrial-control computer boards. Input channels use three-mode redundancy, host controllers two-mode redundancy and output channels use warm redundancy. Experiments and analysis of system reliability by the Markov model indicate that the reliability of normal operation for 5 years is above 0.9.
