Scope

Main Technical Content: 5 Access Requirements 5.1 Power Supply Requirements 5.1.1 Applicable Grid Type The power supply areas suitable for the integration of temporary and permanent power supply modes mainly include A+, A, B, and C categories. In A+ power supply areas, cables should be connected to the grid; in A and B power supply areas, it is recommended to prioritize connecting to cable networks or hybrid cable-overhead line networks, to avoid changes in the overhead line connection points due to the increasing cableization rate of regional lines. In C power supply areas, it is possible to connect to overhead lines or hybrid cable-overhead line networks. 5.1.2 Applicable Grid Structure The cable network structure is generally dual-ring or single-ring. The ring chambers or ring boxes are connected to the backbone network through ring entry and exit, as shown in Figures A.1 and A.2 in Appendix A. Permanent-temporary integration user equipment can be connected to the cable network through ring chambers or ring boxes, as shown in Figure A.3 in Appendix A. The overhead line structure is generally multi-segmented with moderate linkage or multi-segmented single linkage, as shown in Figures A.4 and A.5 in Appendix A. Permanent-temporary integration users can directly connect to overhead line towers through cable lines, as shown in Figure A.6 in Appendix A. The cable-overhead hybrid network used by permanent-temporary integration users should be a non-transitional grid structure. 5.1.3 Access Technical Requirements 5.1.3.1 The open capacity of distribution lines should meet the maximum power consumption requirements of temporary and permanent power supply. 5.1.3.2 Distribution lines should meet the N-1 condition of power grid equipment and comprehensively consider factors such as wire thermal stability and line voltage drop to determine the power supply capacity of typical power supply modes. The power supply capacity of each typical power supply mode
