Embodiment Construction

[0057] see figure 1 , figure 1 It is a flow chart of the steps of the secondary equipment risk assessment method of the present invention.

[0058] The risk assessment method for secondary equipment includes the following steps:

[0059] S101. Preset the weight ratio of each maintenance state parameter of the secondary equipment to the maintenance state value of the secondary equipment, and establish a calculation model of the maintenance state value of the secondary equipment;

[0060] In this embodiment, the calculation model of the maintenance state value of the secondary equipment adopts a tree structure, including a target layer, a criterion layer, a sub-criteria layer and an index layer; wherein, the target layer includes the maintenance status of the secondary equipment state value; the criterion layer includes several evaluation criteria corresponding to the maintenance status of the secondary equipment; the sub-criteria layer includes several sub-criteria correspond...

Abstract

The invention provides a power secondary equipment risk assessment method and a system thereof. By building a calculation model for secondary equipment maintenance state values in advance, the maintenance state values of secondary equipment can be calculated according to the maintenance state parameters of the power secondary equipment. By building a secondary equipment fault probability curve, the maintenance state values are converted into the fault probabilities of the secondary equipment. Then, by building a calculation model for secondary equipment fault loss values, corresponding probable losses caused by all kinds of faults to the secondary equipment are calculated. The products of the fault loss values and the fault probabilities are taken as the risk values of the secondary equipment. Secondary equipment state assessment is closely correlated with risk assessment through the average fault probability of the equipment. The current operation risk of the equipment can be obtained through a state assessment result. Therefore, operators can aim at and well do the operation and maintenance of the equipment according to the calculation results of the risk values, secondary professional operation management can be optimized and objective bases can be provided for equipment type selection and whether the equipment is required to be replaced or not.

Description

technical field [0001] The invention relates to the technical field of electric power secondary equipment maintenance, in particular to a risk assessment method for electric secondary equipment and a risk assessment system for electric secondary equipment. Background technique [0002] With the development of the power industry, the operation, maintenance and management of power secondary equipment has become more and more important. Secondary equipment risk assessment is to comprehensively consider the risks of equipment safety, economy and social impact, determine the risk level of secondary equipment, and provide a basis for decision-making in production management such as equipment operation, maintenance, overhaul, testing, and technical transformation. [0003] The definition of risk in IEEE Standard 100-1992 is widely used in the field of engineering equipment management, that is, risk is defined as "the measurement of the probability (ie failure) and severity of an un...
