Abstract

The invention provides a fault probability calculation method of secondary electric power equipment. The fault probability calculation method of the secondary electric power equipment comprises the following steps of obtaining the quantification value of the operation state of the secondary equipment; obtaining the fault probability of equipment with different state grades; and performing correlation fitting on the quantification value of the operation state of the equipment and the fault probability by a least square method. The invention provides a fault probability resolving method based on secondary equipment state evaluation; and on the basis of completing a state parameter model, a correlation curve of the operation state and the fault probability is fit by the least square method. The method has the advantages that the on-site and historical operation records can be sufficiently used; the fault probability of the secondary equipment is measured and calculated according to the mathematical law; and the data support is provided for the risk quantification evaluation of the secondary equipment.

Description

technical field [0001] The invention relates to a calculation method, in particular to a calculation method for the failure probability of electric secondary equipment. Background technique [0002] Failure probability is an important reliability index of equipment, and it is also the basis for equipment risk assessment. The high-voltage primary equipment used for power transmission and transformation in the power grid directly determines the production process of electric energy transmission, so the statistics and calculation of the failure probability of such equipment are paid attention to. As for the secondary equipment for protection, measurement and control of primary equipment, the normal and reliable operation is also the basic requirement to ensure the stability of the power grid and the safety of power equipment, and it needs to receive equal attention. [0003] The current research on failure probability focuses on the relationship between operating time and equi...
