Predicting and improving power reliability

The availability for use or reliability of a telecommunications installation is dependant on a number of critical factors. Perhaps the most fundamental is whether or not the facility is online with all systems functioning correctly. This state can only occur, and be relied upon, if the systems are operating in environments that they have been designed for and in particular are receiving power of an acceptable quality. This paper explores the reliability of the sources of power available and how they can be used to maintain quality critical supplies at the point of use, thereby improving the reliability of the installation as a whole. This paper discusses power supply systems and reliability study methods. The following power system component sections are described: substations, generators, UPS, data conversion, rotary and hybrid rotary systems, flywheels, and batteries. Reliability improvement and maintenance are also discussed.
