The paper studied and constructed an expert system for vibration fault diagnosis in large steam turbine generator set, and briefly described the structure and function of various components of the expert system, detailed described the knowledge database and inference machine. In this expert system, the knowledge database built on production rule, and the inference machine based on confidence. Finally,...
The paper presents the range and possibilities of using expert systems at diagnostic measurements of insulation systems of power appliances taken by the acoustic emission (AE) method. Multi-parametric descriptors characterizing the AE signals, which can be used in the knowledge base as criteria making the identification of basic partial discharge forms (PDs) possible, have been characterized in detail...
The requirement for power system operators to respond more efficiently to the stressed power system conditions that may create large number of alarms asks fort advanced alarm processor that can help operators recognize the nature of disturbance quickly and reliably. Many of the conventional alarm processors lack the ability to analyze complex events efficiently within a time constraint. This paper...
As high-voltage electric equipment has complex structure and works in harsh environment, FBG (fiber Bragg gating) sensors were applied to realize the real-time monitoring of some characters in which temperature was taken as the main factor. Using neural network to recognize and classify fault types, making a further fusion of fault information by expert system. After simulation and experiment, it...
In this paper, a design mode of expert system for insulation states on high voltage electric equipments is presented. The paper describes the blackboard structure and introduces it to expert system, which can help to make operation decisions for the related personals. This paper elaborates the work mechanism and implementation procedure of the expert system in detail, take the system being used by...
