Study On Integration Technology Of The Typical Intelligent Power Distribution Equipment

Currently,in our country the construction of distribution automation level is relatively low,the integration of distribution equipment and intelligent level is low,although we have to build a sizable all kinds of large and medium-sized industrial parks and residential areas,but most of the park,community intelligent distribution network level is still far,which can not meet the technical requirements for the intelligent distribution network automation system are in the park in island operation state,has not really formed between devices,systems integration and mutual harmony,all sorts of intelligent application functions cannot really play its role.Therefore,in urgent need of the distribution network especially distribution equipment for the file to upgrade,to carry out the distribution of primary equipment and secondary equipment integration,improve the intelligent level of power distribution equipment at a time,to better improve the acceptance ability of the distribution network in the future.Relying on Jiangsu Huaian city distribution network engineering,analyzed the existing primary distribution equipment and technical conditions and application of the intelligent power distribution terminal demand,in-depth discussion of power distribution equipment and intelligent power distribution terminal once fusion and integration technology,the power distribution equipment and intelligent power distribution terminal integration,optimize the operation mode,reduce the equipment installation area,strengthen the integrated equipment functions,implementation of collecting the data of low power distribution equipment and a variety of maintenance mode,and put forward a suitable intelligent power distribution equipment integrationfor Jiangsu Huaian city distribution network,mainly includes the following research content:1,this paper introduces the typical power distribution transformer,circuit breaker,load switch and introduces the typical power distribution equipment state monitoring traditional way at a time.2,a device in a typical distribution circuit breaker as an example,this paper introduces the principle of intelligent circuit breaker monitoring,including circuit breaker operation state monitoring,travel-time monitoring and life on-line monitoring principle,puts forward the concrete scheme of intelligent circuit breaker monitoring transformation.3,puts forward the suitable for smart new intelligent power distribution terminal design scheme of power distribution equipment modification,and based on IEC61850,carried out the modeling of intelligent power distribution terminal and self-describing function implementation,also carried out based on IEC61850 intelligent power distribution equipment state monitoring and modeling.4,puts forward the intelligent power distribution equipment integration solutions,including phased evolution of integrated solutions,put forward the intelligent power distribution equipment and reliable connection mode in the process of integration.To carry out the typical integration technology of intelligent power distribution equipment,can realize the power distribution primary equipment and secondary equipment integration,improve the intelligent level of power distribution equipment at a time,better improve the acceptance ability of the future distribution network,the technical scheme and some equipment demonstration application in Jiangsu Huaian city distribution network,the economic effect is remarkable.
