Data-dimension-based modeling method of setting calculating of relay protection setting value

Abstract

The invention discloses a data-dimension-based modeling method of setting calculating of a relay protection setting value. With the method, a problem of distributed calculation of dispatching at all stages during relay protection setting calculation can be solved; and mutual data interaction can be reduced and the efficiency of combined calculation can be improved. The method comprises the following steps: (1), carrying starting; (2), determining an integration range; (3), carrying out distributed data calling; (4), determining whether data integrity meets a requirement; if so, executing a step (5); and if not, executing the step (3); (5), carrying out a data dimension analysis; (6), carrying out data clustering according to the spatial dimension, time dimension, and type dimension of the data; (7), carrying out data integration; (8), publishing a data integration result to all-stage dispatching; (9), carrying out setting calculation work; (10), determining whether data needs to be updated; if so, skipping to the step (2); and if not, executing a step (11); and (11), carrying out completion.

Description

technical field [0001] The invention belongs to the technical field of power system relay protection setting calculation, and in particular relates to a data dimension-based relay protection setting calculation modeling method. Background technique [0002] With the increasing scale of the power grid, the structure of the power grid is becoming more and more complex, and the operation mode of the power grid presents a variety of characteristics, which puts forward higher requirements for the calculation of relay protection setting. The traditional calculation of relay protection fixed value adopts the distributed modeling mode according to the regulation level, so it becomes very difficult to cooperate with the power grid under the jurisdiction of different regulation agencies. When scheduling distributed computing at all levels, the amount of data interaction is large, and the efficiency of joint computing is low. [0003] The expansion of the scale and the complexity of t...
