U.S. Power Reliability: Are We Kidding Ourselves? | TD World

Difficult to Compare Reliability LevelsDifferent Consumer PerceptionsAccess Over ReliabilityThe European PerspectiveDr. Matthew C. Cordaro “All I know is that when I was on the EPRI board, I saw many of their studies that showed the U.S. system to be at least 99.99 percent reliable. The big question and goal for them was what we needed to do to move to 6 nines reliability.”–Matt Cardaro Stepping back from this and considering the big picture, it is really difficult to compare reliability levels unless the systems being considered are very similar in almost all respects, including the severe weather conditions they may experience. Even in the U.S. alone it is almost impossible to compare utility reliability, especially when different systems use different assumptions. and record and tabulate their indices in different ways. In fact. a number of utilities in this country do not even report their reliability results to a central collection agency or industry group. I have not studied the foreign data to any extent, but are all these countries measuring reliability in exactly the same way using the s...Get price

High voltage substations overview (part 1) | EEP

Circuit ConfigurationProtective MeasuresArrangement and ModulesHigh voltage substationsare points in the power system where power can be pooled from generating sources, distributed and transformed, and delivered to the load points. Substations are interconnected with each other, so that the power system becomes a meshed network. This increases the reliability of the power supply system by providing alternate paths for flow of power to take care of any contingency, so that power delivery to the loads is maintained and the generators do not face any outage. The high voltage substation is critical component in the power system, and the reliability of the power system depends upon the substation. Therefore, the circuit configuration of the high voltage substation has to be selected carefully. Busbars are the part of the substation where all the power is concentrated from the incoming feeders, and distributed to the outgoing feeders. That means that the reliability of any high voltage substation depends on the reliability of the busbars present in t...Get price
