Abstract

The invention provides a method for monitoring the operation conditions of power primary equipment. The method comprises the steps of signal acquisition, analysis and transfer, diagnosis and estimation and the like. The invention also provides a monitoring device matched with the method. An operating power grid is monitored in real time by use of a non-contact vibration spectrum monitoring and infrared detection mode, the characteristic curve data is generated for the vibration and temperature parameters of the primary equipment, and a complete expert system is established by use of the fuzzy mathematics theory and artificial neural network. The abnormality prediction diagnosis detecting the abnormal sign at the preliminary service stage of the equipment and the aging diagnosis of the equipment performance changing year by year are realized. Whether the equipment fails or whether overhauling is needed is determined through the self-learning self-diagnosis fuzzy theory. Whether the equipment fails is analyzed and the fault type is diagnosed through the vibration spectrum monitoring and infrared detection technology in combination with an intelligent diagnosis system, thereby effectively improving the operation efficiency of the primary equipment and pushing forward the further development of intelligent power grid.

Description

technical field [0001] The invention belongs to the field of power system monitoring, in particular to a method and a device for real-time monitoring of the operating conditions of primary equipment in a power system. Background technique [0002] Condition maintenance of power equipment is currently in the ascendant at home and abroad, and more and more power equipment is included in the category of condition monitoring. With the development of sensing technology and computer technology, multi-function, multi-state online monitoring system will be developed. At present, most of the primary equipment in the power system adopts the planned maintenance system (such as temporary maintenance), which has serious defects, which causes waste of human and financial resources, and also has a certain impact on the reliable operation of the power grid. The proposal of smart grid makes people pay attention to real-time monitoring of grid equipment, especially primary equipment. If the...
