Embodiment Construction

[0035] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] The specific steps of the fault early warning method for random power access equipment in this embodiment include the following:

[0037] 1) Obtain equipment information, equipment alarm information and equipment maintenance record information in real time;

[0038] 2) According to the equipment information, equipment alarm information and equipment maintenance record information, calculate the expected service life of the equipment and the correlation between the alarm type and the fault type, the correlation between the equipment use frequency and the fault type, the equipment use frequency and the alarm type According to the correlation degree between levels, determine the fault type corresponding to each alarm type, and calculate the corresponding type of fault occurrence probability according to the alarm type sending fre...

Abstract

The invention relates to a fault early warning method for random power access equipment. The method includes: 1) obtaining equipment status information, alarm information and maintenance record information in real time; life, the degree of correlation between alarms and faults, the degree of correlation between frequency of use and faults, the degree of correlation between frequency of use and alarms, and then calculate the probability of failure; Send an early warning signal to replace the equipment as soon as possible, otherwise, judge whether the probability of failure is greater than the preset value, if so, perform an early warning and push the location information of the equipment and the type of pre-occurring failure to the operation and maintenance personnel. The method of the present invention pushes the possible failure types and failure probability of the equipment in time, and performs maintenance before the failure probability, thereby improving the normal operation time of the random power supply and further promoting the construction of the random power supply.

Description

technical field [0001] The invention specifically relates to a fault early warning method for random power access equipment. Background technique [0002] Low-carbon economy and sustainable development are the inevitable requirements for the sustainable development of human beings. The application of renewable energy, energy storage, and electric vehicles is growing rapidly. New energy is connected to the power grid through power electronic equipment, and the utilization level of equipment is directly related to new energy. develop. [0003] The development of new energy involves a wide range of areas, and investment owners are concerned about their return on investment, hoping to reduce downtime and recover costs quickly; power grid operation companies are concerned about their impact on the power grid, and hope that equipment failure will cause greater uncertainty to the power grid; Users (and possibly investment owners) pay attention to safer and more reliable applicatio...
