Generator rental has become the main unit of the power grid-in order to prevent accidents in the operation of large-capacity generators, on the one hand, we must solve the quality of the generator design and manufacturing process; on the other hand, we must improve the level of operation and maintenance, improve the quality of unit installation and maintenance, and carry out Research on online monitoring and diagnosis technology to eliminate latent faults of generators to prevent sudden accidents and reduce accident losses is necessary-at present, hydrogen-cooled generators overheating alarms, RF monitors, hydrogen leakage and hydrogen humidity have been developed in China Monitoring, brushless excitation generator rotor current and temperature monitoring, etc., and have played a great role-but these devices often run independently, and some devices output data can only explain indirect information about the potential failure of each part of the motor, some Difficult to determine the safety margin of operation-due to the large number of protective devices, it is difficult to deal with parameter out-of-bounds alarms, and because a large amount of information may be incomplete, inaccurate, or even contradictory, a little carelessness or delay by decision makers may cause a significant economy Loss and social impact-so this information needs to be processed automatically, Study online monitoring data fusion generator rental purpose is to use information fusion technology to the field of industrial measurement and control, ensure the unit safe, stable and economical operation.
Application of data fusion in fault diagnosis of generator rental
Application of data fusion technology in generator fault diagnosis Synchronous generator rental is the basic equipment for generating electrical energy and is the heart of the power grid. Its operational reliability directly affects the operation of the power grid and whether it can supply power to users safely and economically. For generator leasing, it is not only a priority to improve product quality and reliability during the design and manufacturing stages, but also to implement online monitoring and diagnosis after grid-connected operation has become an urgent issue. Its main purpose is: to check the defects of the generator in the initial stage so as to arrange maintenance in a planned way, thereby reducing the number of forced shutdowns and avoiding accidents; meanwhile, extending the mean time between failures of the generator and shortening the average repair time and reducing maintenance costs And improve generator availability. In order to ensure the safe and reliable operation of generators, some countries around the world have carried out research on online monitoring and diagnostic technologies in recent decades, and gradually promoted their application. In the previous annual conferences of CIGRE since the 1980s, generator fault monitoring and diagnosis has been listed as one of the central topics of the SC-11 (rotary electric machine) committee. In recent years, research and adoption of data fusion technology expert diagnostic systems have been started, making diagnostic technology develop to a more advanced level.
Data fusion is an automatic information comprehensive processing technology formed and developed in the 1980s. It makes full use of the complementarity of multi-source data and the high-speed operation and intelligence of electronic computers to improve the quality of the resulting information. This technology was first widely used in the military, and soon spread to the fields of automatic control, medical diagnosis of air traffic control, and so on. The application of data fusion technology for fault diagnosis in generator online monitoring has a good application prospect.
Generator rental operation monitoring data comes from different sensors. For example, the stator winding insulation online monitoring can obtain the RF level value of the RF monitor, or the current indication value measured by the local overheating monitoring device. http://hzbxx.cn/
