Research On Interface Problems In Automatic Verification System Of Current Transformers

With the development of our country’s electric power business, the currenttransformer which is most widely used in power system makes an increasingly importantposition in the implementation of network reconstruction. However, the accuracy andreliability of the current transformer’s performance indicators including insulation, error,angular, compression and magnetic saturation have a great influence on the safe andreliable operation of the power system. Especially, because of the traditionally artificialverification which exists many problems such as large amount of operation, strongrepeatability and low efficiency of verification, it is in great need of finding a highefficiency and automatic verification system for verifying transformer regularly, to ensurethe error of the performance index keeps in a reasonable scope, and to guarantee the wholepower system operating safely and orderly.Based this background, this thesis discusses about designing automatic verificationsystem of measurement with low voltage current transformer, and deeply studies theinterface design and interactive between measuring integration platform and transformerverification system. Then the released Web service interface is employed and tested byusing the software testing method. At the beginning, this thesis analyzes and summarizesthe method of current transformer verification to this day. Then it focuses on the demandof the eight functions and the interface design of the3-tier model of verification system,and briefly illustrates the adopted XML agreement for the interactive interface. Moreover,according to the interactive features between the measuring integration platform and thetransformer verification system, it takes the SetDetectNotice interface for example torealize the features such as convenient, security and cross-platform with the unifiedinterface calling method of combining Web service with the staging data base. Finally, ittakes the basic path testing method which is one of the white-box testing methods, to testand verify the interface’s business process logic in Web page and Form separately.
