Problems solved by technology

Since the launch of the DL / T860 standard, it is obvious that the original modeling method cannot meet the requirements of the existing standard and does not meet the bidding specifications of the State Grid
The original model file has poor interoperability because different manufacturers create different logical nodes LN

Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] The network topology of the station integrated power supply system is as follows: figure 1 As shown, the entire substation low-voltage power supply equipment shares one IED file. The integrated power supply system IED adopts serial communication with DC power supply LD, AC power supply LD, communication power supply LD, UPS power supply LD and total monitor LD, and DC, AC, communication and UPS power supplies are connected to the integrated power supply system as logic devices LD middle.

[0042] The DL / T 860 standard stipulates for substation low-voltage power supply equipment: each minimum functional unit that needs to communicate is modeled as an LN object, and the data and data attributes belonging to the same functional object are placed in the same LN object, in order to ensure interoperability Therefore, it is not recommended to create a...

Abstract

The invention discloses a DL / T860-based method for realizing the modeling of power supply equipment for substations, including the following steps: importing the provided default ICD file, judging whether the port configuration of the power supply equipment for substations has changed; backing up the IED performance description file and mapping file; start to generate IED performance description file according to DL / T860 standard; judge whether generating IED performance description file fails; use default IED performance description file; generate corresponding mapping file according to IED performance description file; verify IED performance description file and mapping Whether the file is correct; the power supply equipment used in the substation starts normally. The invention has the advantages of automatic generation of IED performance description (ICD) files, low technical requirements for staff, small workload and accuracy.

Description

technical field [0001] The invention relates to a method for realizing modeling of power system components, in particular to a method for realizing modeling of power supply equipment for substations based on DL / T860. Background technique [0002] At present, the low-voltage power supply equipment in substations is modeled using the 61850 model file implemented by the IEC 61850-7-420 standard. The IEC 61850-7-420 standard does not list the relevant extension classes for the logical nodes of the low-voltage power supply equipment in substations. Since the launch of the DL / T860 standard, it is obvious that the original modeling method cannot meet the requirements of the existing standard and does not meet the bidding specifications of the State Grid. The original model files have poor interoperability because different manufacturers create different logical nodes LN. [0003] The 61850 model file has been completed by manual editing. Manual editing of IED (intelligentelectroni...
