| In the power system and various user systems,high-voltage electrical appliances and switching equipment have an important position and role,with the development of power systems,generating,transmit,power supply and reliability requirements are getting higher and higher.SF6 Insulated Switchgear(GIS,Gas Insulated Switchgear)has many advantage like small footprint,low noise,no fire hazard,long maintenance cycle,safe and reliable operation,with excellent performance of closed combination of electrical,strong ability to start and safet y and reliability Get the power market is widely recognized,at this stage GIS has gradually replaced other switching equipment and become the mainstream varieties.GIS equipment will circuit breakers,isolating switches,bus and transformers soaked in high-performance insulation materials,complex structure,manufacturing process,the maintenance of technical means and reliability of the state assessment put forward higher requirements.The status of GIS equipment has a direct impact on the safety of power system and the reliable operation of power grid.Therefore,it is of great practical significance to carry out the evaluation of state condition and optimal condition maintenance of GIS equipment.The status of GIS equipment assessment and its optimal state maintenance strategy are explored scientificly in this paper,the main work is as follows:1.Analyze the fault characteristics of GIS equipment in the life cycle,discuss the general idea of establishing the state evaluation method,the index system,model and method of equipment evaluation.By analyzing the factors that affect the running status of GIS equipment,combined with the existing state parameters data acquisition means,to determine the status of GIS equipment parameter evaluation system,as well as the value of the parameters of the standard.2.Study the characteristics of GIS equipment state parameters and the method of obtaining the method and the method of determining the weight of each state parameter.The reason why the state model is calculated by fuzzy analytic hierarchy process is discussed.The state evaluation model of GIS equipment based on fuzzy analytic hierarchy process is established.The model is used to verify the influence of the underlying state parameters of typical GIS equipment on the overall evaluation of equipment,which has certain practical application value.3.Put forward the object and method of GIS status evaluation software platform design,use ACCESS database and Visual C ++ programming language to compose the state evaluation information software of GIS equipment,put the mathematical process involved in the evaluation model into the program,simplif y the evaluation of GIS equipment status model of the application,easy to equipment status evaluation of information management. |
