Abstract

The invention discloses a model sharing method between a power distribution main station and a terminal. The method comprises the following steps of comparing an update time t1 with a last update time t2, and if t1>t2, updating a power distribution terminal model; obtaining a to-be-updated model; performing mapping association between an IEC61968/IEC61970 model in the power distribution main station and a terminal model based on the IEC61850 standard; comparing with a current mode after the power distribution terminal receives an updated file; uploading a model comparison result by the power distribution terminal; sending an operation instruction by the power distribution main station according to the comparison result; conducting operation by the power distribution terminal according to the operation instruction; and uploading a final update time of the power distribution terminal model by the power distribution terminal. The invention utilizes the mapping function of the IEC61968/IEC61970 and IEC61850 models and provides a powerful guarantee for rapid and accurate position and processing of power distribution network faults.

Description

technical field [0001] The invention relates to a model sharing method between a power distribution master station and a terminal based on IEC61968 / IEC61970 and IEC61850 standards, and belongs to the technical field of distribution network automation. Background technique [0002] With the increase in the reliability and safety requirements of distribution network power supply, the degree of automation of distribution network is also increasing year by year, and the number of distribution automation terminals is increasing day by day. At present, the distribution network feeder automation mainly adopts two modes: centralized and distributed. The centralized fault handling mode needs to be operated through the research and judgment of the master station, which is difficult to cope with the access of massive data, which seriously affects the speed and accuracy of fault handling; the distributed fault processing mode handles faults on the spot through communication between term...
