Options for increasing the reliability of electric power objects by methods of reserving elements |
S.E. STEPANOV
The ways of improving the reliability of the operation of electric power facilities by reserving the elements of power supply systems are considered, using the example of compressor stations and line consumers. Variants of realization of various kinds of structure formation of power supply systems of objects of the raised danger are offered. Theoretically grounded reliability calculation indices are presented, which allow estimating the probability of failure-free operation and the average time of trouble-free operation for various methods of reserving systems. Numerical reliability calculations for typical examples of power supply systems with redundancy are performed. It is shown that the best reliability indicators are provided by the power supply systems of compressor shops with redundant backup and with sliding backup. Structural schemes for the practical implementation of methods for reserving electric power facilities and estimating reliability indicators are also presented, based on the design features of the main gas pipelines.
Keywords: reliability, power supply system, redundancy, probability of failure-free operation, average time of trouble-free operation.
