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.2 Normative referencesThe following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 2900.49 Electrotechnical terminology - Power system protection (IEC 60050-448:1995, IDT) IEC 61850 (all parts) Communication networks and systems in sub-stations ISO/IEC 9314-3:1990 Information processing systems - Fibre distributed data interface (FDDI) - Part 3: Physical layer medium dependent (PMD)]3 Terms and definitions, abbreviations3.1 Terms and definitions For the purpose of this document, the terms and definitions defined in GB/T 2900.49 and following apply. electrical signals of analog quantity and switching value in the station and converts them to SV and GOOSE signals and sends upstream to the station domain control substation; the GOOSE trip command or control command sent downstream by the station domain control substation is converted to analog signal by the intelligent acquisition device for operational control. d) It uses SV and/or GOOSE transmission mechanism to transmit analog quantity and switching value information between the station domain control substation and the area control master station. 4.2 Station domain control substation information interface The station domain control substation information interface shall follow the following principles: a) The station domain control substation should have an interface to obtain information such as power, voltage and current RMS values of the station through station control layer equipment. b) The station domain control substation shall have a process layer communication interface, and can obtain analog quantity and switching value through process layer equipment or intelligent acquisition device. c) The in-station data transmission shall meet the requirements of SV and/or GOOSE transmission mechanism.5 Inter-station communication5.1 Inter-station (between distribution terminals) communication principles The substation inter-station communication shall follow the following principles: a) The inter-station communication should adopt peer to peer communication network topology, and have ring protection function and network self-healing capability. b) The inter-station communication data interface shall be compatible with transmission equipment such as SDH/MSTP, PTN, OTN, EPON. c) The inter-station communication shall support the transmission of analog quantity and switching value data, and the data shall be guaranteed in real time. d) The regional power grid with regional differential protection function shallAnnex 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. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
