Early warning method for generator overheating fault hidden danger based on three-dimensional display

Abstract

The invention relates to an early warning method for a generator overheating fault hidden danger based on the three-dimensional display. The method comprises the following steps: (1) establishing a generator three-dimensional model by utilizing a generator design drawing; (2) introducing temperature measuring points and operation data, establishing a technology supervision interface; (3) running the three-dimensional model of the generator, and displaying the running state of the running data and the temperature measuring point; (4) checking whether the running parameters exist or not, and carrying out relevant curve analysis; (5) judging whether a generator overheating fault occurs or the measuring point is abnormal; (5) if the temperature measuring point is abnormal, replacing the temperature measuring point, and providing a temperature measuring point position space display; (6) if the generator overheating fault occurs and the generator needs to be shut down, running the monitoringoperation before the shutdown of the generator. According to the method, the three-dimensional display advantages are fully utilized, and the important equipment and the running data of the generatorare displayed in real time. When the temperature of the generator is found to be abnormal, a preliminary judgment conclusion for whether the temperature of the adjacent parts is reasonable or not isobtained according to the space position. Necessary processing measures are adopted, and accidents caused by the technical analysis process are avoided.

Description

technical field [0001] The invention belongs to the technical field of production safety and accident prediction, and relates to a three-dimensional display-based early warning method for potential generator overheating faults. Background technique [0002] The main equipment of large-scale thermal power plants includes boilers, steam turbines and generators, etc., whose role is to completely convert heat energy to mechanical energy and then to electrical energy. The coupling between equipment and the complexity of the system, etc., determine that the thermal power plant is a production site with high failure aluminum and great damage. These failures will cause major economic losses and social consequences. Therefore, it is necessary to detect and analyze the equipment status parameters through the technical means of fault diagnosis to judge whether there is any abnormality in the equipment, the location and cause of the fault, the deterioration trend of the fault, and the t...
