GB/T 37155.2-2019Technical guidance of protection and control system on regional power grid—Part 2: Information interface and communication (English PDF)

1 Scope

This Part of GB/T 37155 specifies the information protection communication principles and information interfaces based on IEC 61850 of protection and control system on regional power grid, as well as the requirements of inter-station communication principles, communication interfaces, communication protocols and inter-station information configuration methods.

This Part applies to protection and control system on regional power grid, of which the voltage level is 110 kV and below. The same type of protection and control system on regional power grid with other voltage levels and the same power grid reliability problem may refer to this Part.

Annex A (informative)

Step example of inter-station information configuration process The inter-station information configuration process is implemented by referring to the following steps (taking Figure A.1 as an example):

a) Station 2 exports the SED2 file containing the inter-station information and sets the engineering configuration permission attribute of the communication interval of this station. For example, in Figure A.1, the station domain control substation AA2 exports the SED file containing the communication interval IED AA2F1, i.e. SED2, and sets the engineering configuration permission engRight attribute of AA2F1 to "data flow", allowing engineering configuration; the engRight attribute of other interval IED is set to "fix", not allowing configuration.

b) Station 1 imports the SED2 file and completes the inter-station information connection between the communication interval of this station and the communication interval of station 2. For example, in Figure A.1, the regional control master station AA1 imports the SED2 file of the substation AA2, and completes the virtual terminal connection between the communication interval AA1F2 of this station and the communication interval AA2F1 of station 2.

c) Station 1 completes the inter-station information configuration of the communication interval of this station, sets the engineering configuration permission attribute of the communication interval of this station, exports the SED1 file. For example, in Figure A.1, the master station AA1 uses the IED configuration tool to complete the virtual terminal configuration of the communication interval AA1F2 of this station, and derives a SED1 file with the same ID (identification) as the SED2 but has been instantiated. The engRight attribute of the communication interval AA1F2 of this station is set to "fix", and the engRight attribute of the communication interval AA2F1 of station 2 is still "data flow".

d) Station 2 imports the SED1 file and completes the inter-station information configuration and in-station information configuration of the communication interval of this station. For example, in Figure A.1, the substation AA2 imports the SED1 file, implements the inter-station information configuration of the communication interval AA2F1 of this station, and uses the IED configuration tool to complete the in-station information configuration.
