Research On-linetransformer Condition Monitoring System

Power transformer to adjust voltage level,an important task of energy transmission and tide control,is the core of electrical equipment in power system,in order to improve the stability of the power transformer,high efficiency,safety,and the long run,real time control of the transformer by the state data of abnormal condition and maintenance,fault will be nipped in the bud,so that enhance the stability of system operation still can lengthen the operation life of the transformer,this paper puts forward to establish multiple monitoring subsystem of transformer on-line monitoring system for research.By itself the power transformer structure and compare the three types of fault analysis,grasp the common failure forms and important parameters of transformer,and the gas chromatography,micro water content in oil,iron core earth current,the temperature measurement,vibration,oil level principle of on-line monitoring system for interpretation and the overall design idea,and according to the requirements of on-line monitoring system,more hardware equipment selection and optimization scheme of system,and design the circuit loop,successful structures can meet the design thought of hardware platform.Provide hardware assurance for real-time control of transformer status data.According to the characteristics of different monitoring subsystems,the composition of multi-child system is designed according to the characteristics of different monitoring subsystems.Citing the different system monitoring and fault types by the acquisition module workflow,to enable staff to transformer monitoring the relevant information in a timely and effective manner,to respond in a timely manner,in order to obtain optimal results,system using configuration software to monitor transformer,configuration software to gather relevant information from automation equipment,and the information in the form of graphics,such as better,easy to understand and analysis,to convey important information in a variety of means to the related staff,make information processing,storage and analysis a control instruction,etc.In order to establish the on-line monitoring system building strategy,the construction of multiple online monitoring systems and remote monitoring are realized.Finally,a substation transformer on-line monitoring system for the practical example,this transformer on-line monitoring system characteristics,and through the acquisition of data,this paper compares and analyzes relevant subsystem and verify the correctness of the on-line monitoring system for fault diagnosis,the main content is divided into two parts: the first part ofthe multiple subsystems,for example to analyze its key technology;The second part of the transformer on-line monitoring system for actual validation into line,through multiple sets of data analysis to illustrate how monitoring subsystem operation.
