Problems solved by technology

The specific method is that for each key monitoring node of the power generation equipment, the alarm, early warning, and upper and lower limit thresholds of faults are manually set based on experience, and the real-time monitoring data is compared with the threshold to confirm whether the current equipment is in normal working state; this This method separates each key feature of the power generation equipment, and cannot comprehensively consider the operating status of the equipment. At the same time, when the number of key features of the equipment is large, it is not conducive to the overall analysis of the equipment.

Abstract

A power generation equipment fault detection method and system, comprising: bringing the current power generation power of the power generation equipment into a pre-established power generation equipment fault detection fitting model to obtain a current voltage fitting value; based on the current voltage fitting value, voltage monitoring determine whether the power generation equipment is currently faulty; bring the predicted time into the pre-established power generation equipment operation situation prediction model to obtain the voltage predicted value of the power generation equipment at the predicted time; determine the power generation equipment predicted time based on the voltage predicted value Whether there is a fault or not, through real-time detection of whether the power generation equipment is faulty and the operation situation after a certain period of time, the fitting data and prediction data of the key characteristic features related to the power generation equipment are provided to make the detection results more convincing and improve the normal operation of the power generation equipment. safety in the process.

Description

Technical field: [0001] The invention belongs to the field of power generation equipment fault detection, and in particular relates to a power generation equipment fault detection method and system. Background technique: [0002] Since the industrial revolution, the functional requirements for equipment failure detection have emerged. Generally speaking, workers judge whether equipment has failed or not, mainly through long-term accumulated experience or observation of equipment appearance. . With the rapid progress of industrial development, industrial equipment is also developing day by day, developing in the direction of intelligence, large-scale, high-speed and distributed. Compared with the traditional equipment, the structure of the equipment is more complex, and at the same time, the functions are more powerful, which increases the difficulty of maintenance. Then, the probability of equipment failure has been greatly increased compared with before, and the informati...
