Abstract

The calibration of electronic transfer’s digital out is significant part for the reliable operation of intelligentsubstation. Due to China has a vast territory

and the temperature changes greatly when the season changes

accord-ing to the particular condition in alpine region

a new idea of an calibration system and a message-analysis sub soft-ware is proposed

which base on IEC6 1850-9-2 is developed by C++ language. For its particular use

the hardwareimproves the accuracy and stability of the calibration device by the selection of low-temperature environment elec-tronic components;The software solves the influence of the differential part of Rogowski coil transformer through theHilbert algorithm

and effectively reduce interference of non-synchronous sampling grid frequency fluctuation errorresults through quasi synchronization algorithm

the multi-thread method guarantees the higher efficiency of the multi-task processing such as sampling

message parsing

algorithm

display and storage processing in the calibration sys-tem. Finally

the test results of the electronic transformer in the low temperature environment in Heilongjiang

Thesystem fulfils requirements of on-site testing.
