MOA condition management and fault prediction method and MOA condition management and fault prediction system

Abstract

The invention discloses an MOA condition management and fault prediction method and an MOA condition management and fault prediction system. The method comprises that an MOA condition management and fault prediction model is established, and takes MOA characteristic parameter data as input and the MOA condition as output; operation data related to different MOA conditions is calculated, and a training knowledge base is established based on the calculated operation data; the MOA condition management and fault prediction model is trained by utilizing data stored in the training knowledge base; and the MOA characteristic parameter data measured in real time is input to the trained MOA condition management and fault prediction model to obtain the MOA condition. According to the technical scheme, the operation data that reflects the different MOA conditions is calculated to train the MOA condition management and fault prediction model, and then the real-time MOA characteristic parameter data is input to the trained MOA condition management and fault prediction model to obtain the accurate MOA condition, and basis is provided for MOA maintenance.

Description

technical field [0001] The invention relates to the field of system management, in particular to a MOA health management and fault prediction method and system. Background technique [0002] Zinc oxide surge arrester (referred to as MOA) is an important protection device to protect high-voltage power devices from lightning and operating overvoltage hazards. Its safe and reliable operation is very important to power systems. It has been widely used in my country's 10-500kV power grids. Due to the long-term power frequency voltage of MOA, as well as the influence of impulse voltage and internal moisture, the internal valve plate will deteriorate, the resistive current will increase, and the power consumption will increase, resulting in an increase in the temperature of the MOA internal valve plate, and even thermal collapse, causing The explosion of MOA endangers the safe operation of the power system. [0003] With the development of electronic technology, sensor technology,...
