Design And Research On The Intelligent Control System Of The Operating Parameters Of Transformer

In the process of power system operation，electrical equipment can be safe andreliable operation or not plays an important role in the system safety. With the growth inthe living standard and the development of science and technology, the power grid hasgradually expanded the scale; meanwhile the performance of electrical equipment isalso put forward higher requirements. The power transformer is the importantequipment in power system, its safe and reliable operation has great significance forpower system. Therefore, how to timely and accurate grasp the running state oftransformer, did great significance to the reliability of power system and the transformerrepair. At present, the domestic research gives more and more attention in this field, andalso achieved some results. Therefore this paper comprehensive the operation state oftransformers research, apply expert system and fuzzy theory evaluate the operation stateof transformers.This paper first introduces the current common transformers and its fault types aswell as fault symptoms, and then put forward the thought of expert control system,through the expert control system to determine whether the operation process oftransformer is in the normal state, and at the abnormal state,the system can makes rapidand accurate diagnosis. In the process of diagnosis, this paper combined with humanexperts described the characteristics of fault; it proposed fault diagnosis algorithm basedon fuzzy mathematical model. Finally the transformer operation parameters ofintelligent monitoring system combined with the knowledge of database theorywhichimplement on VB6.0platform. The platform operate easily and has friendlyinterface, the diagnosis results are satisfactory.
