Problems solved by technology

[0002] The secondary system in the distribution network plays an irreplaceable role for the distribution network. Data collection and fault protection are the two most important functions of the secondary system. Evaluate the reliability of the secondary system to be built. In this case, the reliability of the completed secondary system is unknown, and it is likely that the reliability of the completed secondary system is poor, such as communication failures and Misjudgment of the fault location, etc., the construction of the secondary system is relatively blind. If the reliability of the built secondary system is poor, it will lead to higher maintenance costs

Abstract

The invention discloses a power distribution network secondary system reliability assessment method and device, equipment and a storage medium. The method comprises the steps of simulating operation time and fault repair time of equipment with shortest normal operation time in a primary system and a secondary system to be tested according to reliability parameters of all equipment of the primary system and the secondary system to be tested; determining work task completion data of each secondary device according to the operation time, the fault repair time and the corresponding relationship among the operation time, the fault repair time and the work task completion data of each secondary device; and determining a terminal online rate, a fault correct reflection rate and a terminal correctaction rate of the secondary system to be tested according to the work task completion data and a corresponding relationship between the work task completion data and a preset index, so as to evaluate the reliability of the secondary system to be tested. The reliability of the secondary system to be tested is evaluated, so that the reliability of the constructed secondary system is higher, and the later maintenance cost is reduced.

Description

technical field [0001] The present invention relates to the field of power systems, in particular to a method for evaluating the reliability of a secondary system of a distribution network. The present invention also relates to a reliability evaluation device, equipment and a computer-readable storage medium for a secondary system of a distribution network. Background technique [0002] The secondary system in the distribution network plays an irreplaceable role for the distribution network. Data collection and fault protection are the two most important functions of the secondary system. Evaluate the reliability of the secondary system to be built. In this case, the reliability of the completed secondary system is unknown, and it is likely that the reliability of the completed secondary system is poor, such as communication failures and Misjudgment of the fault location, etc., the construction of the secondary system is relatively blind. If the reliability of the built seco...
