| Nowdays, Intelligent substation are usually equipped with Transformer on-line monitoring system,Video surveillance system,Burglar alarm security system,Fire alarm system, The main transformer fire system, Heating and ventilation system and other auxiliary control system of different functions.Because the equipments types and interface standards are always different,there is no linkage in these subsystems.And at the same time,the auxiliary control system produces mass of real-time monitoring data and historical data. The mass data can’t be entirely processed and analysis by the labour,so as to increase the operation personnel work load.Based on the existing hardware in order to classification the alarm information data of auxiliary control system fastly and precisely to provide aided decision for operation and maintenance personnel of auxiliary control system operation.This paper introduces the status of development of intelligent substation and its auxiliary control system,and the development history,theory,methods,and the advantages of application in the power system of data mining technology.And apply the classification methd of data mining in data processing of auxiliary control system. The paper introduce classification of the data mining method into auxiliary control system of the data processing, establish the alarm information system and the data warehouse, characteristics of warning data analysis, research and that adapt to the mining theory and mining method.The paper design the Alarm Information Classification Model, analysis the transformer monitoring alarm information and environmental alarm information and establish classification model respectively.At the end, the paper take part of the data of Wu XI Xi Jing Intelligent Substation as test exemple to prove the practical utility and the effectiveness of this method. |
