A non-interpolation wave recording method adapting to point-to-point mode in smart substation

Abstract

The invention discloses a non-interpolation wave recording method adapted to a point-to-point mode in an intelligent substation. This method makes full use of the skew field in the standard comtrade format, calculates the skew every period of time according to the receiving time stamp and rated delay of the message, and fills this field into the configuration file of the recorder file to form the final recorder document. This method can preserve the original data of the channel to the greatest extent, and at the same time ensure that the phase difference of different channels in the recorded wave file is within a certain range.

Description

technical field

[0001] The invention belongs to the field of electrotechnical technology, in particular to a non-interpolation wave recording method adapting to a point-to-point mode in an intelligent substation. Background technique

[0002] In the point-to-point mode of the smart substation, the current fault recorder generally uses the interpolation method to complete the wave recording. This method does not save the original value of the merging unit, and may cause high-order harmonic data distortion, so it is not the best method. Methods.

[0003] Therefore, a new technical solution is needed to solve the above problems. Contents of the invention

[0004] The object of the present invention is to provide a non-interpolation wave recording method adaptable to point-to-point mode in an intelligent substation capable of better retaining the original data of the channel in view of the deficiencies in the prior art.

[0005] In order to solve the above problems, the pres...
