Field checking method for intelligent substation protection equipment download configuration virtual terminal

Abstract

The invention discloses a field checking method for an intelligent substation protection equipment download configuration virtual terminal. The field checking method comprises the steps of reading a protection equipment process layer downloading configuration file, parsing and combining to form protection equipment SV, a GOOSE reception control block and a GOOSE transmission control block after the virtual terminal is checked to be correct, transmitting power grid normal state, faulty state SV and GOOSE messages to the protection equipment and conducting a GOOSE switching-out test, and checking whether the protection equipment download configuration virtual terminal is correct in the field. The field checking method provided by the invention is a means for checking whether the field protection equipment virtual terminal download is correct, does not rely on an SCD file, is high in field checking efficiency, is convenient for timely discovering potential hidden dangers of SCD file virtual terminal download, and is high in field adaptability.

Description

Technical field [0001] The present invention relates to the technical field of smart substations, and in particular to a method for on-site verification of virtual terminals installed in the protection equipment of smart substations. Background technique [0002] With the vigorous development of smart substations, the analog transmission in conventional substations has become the current digital transmission, and the loop information between various devices has changed from cable transmission in the past to fiber transmission in the present, and many transmission loop information is invisible Can't touch it. All the circuit information of the intelligent substation is integrated in the SCD file; each protection device of the substation also needs the SCD file to export the corresponding configuration file, and can work according to the configuration information after downloading. The downloading configuration of the protection device includes the station control layer MMS data mo...

Problems solved by technology

State Grid’s Sixth Unification and Ninth Unification Standards have unified the configuration files of various manufacturers, but many device configuration files before the Sixth Unification are still downloaded according to private files

Theoretically, the configuration information integrated in the SCD file is completely consistent with the actual working configuration information of each device. However, at present, the configuration virtual terminal of a device is temporarily modified before the substation acceptance, and the SCD file is not updated in time, resulting in the user getting the current substation. The SCD file is not up-to-date. At this time, it is impossible to communicate with the actual device during debugging, and the format of the downloaded configuration file is not uniform. Only by communicating with the manufacturer can debugging be done, which increases the debugging time and prolongs the operation and maintenance cycle.

At present, the test equipment on the market needs to import the SCD file to work. When the protection equipment is replaced, overhauled or newly commissioned, if the final version of the SCD is uncertain or the SCD file cannot be obtained temporarily, it is impossible to calibrate the virtual terminal of the on-site protection equipment in time. test
