The difference between the public connection points of photovoltaic power stations and network access points
The difference of grid point, access point and public connection point of photovoltaic power station In the following figure, which of A1, A2, B1, B2, C1, C2, and D belong to? 1) Access point, 2) Grid point, 3) Public connection point Dear friends, as a veteran of PV power stations, don’t say wrong! The correct answer is this: The following is a professional interpretation of the State Grid Corporation. In the grid connection point, for the distributed power supply with a booster station, the connection point is a bus or node on the high side of the distributed power booster station; for a distributed power supply without a booster station, the connection point is the output summary point of the distributed power supply. As shown in the figure, points A1 and B1 are the grid connection points of distributed power sources A and B, respectively. Point C1 is the connection point of the regular power supply C. The access point refers to the connection of the power source to the power grid. The power grid may be either the public or the user's power grid. As shown in the figure, points A2 and B2 are the access points of the distributed power supply A and B, respectively, and the access point C2 is the access point of the regular power supply C. 3. The public connection point refers to the connection between the user system (power generation or electricity use) and the public power grid. As shown in the figure, C2 and D are common connection points, and A2 and 82 are not public connection points. 4. Access to system engineering, as shown in the figure, A1-A2, B1-B2 and C1-C2 transmission and transformation projects and the corresponding power grid renovation projects are distributed power supply A, B and conventional power supply C access system engineering A1 -A2 and B1-B2 power transmission projects are invested by users. The C1-C2 power transmission project is invested by power grid companies. 5. Special line access refers to the distributed power supply special switch equipment (interval) at the distributed power access point. For example, the distributed power supply directly connects to the substation, open and close station, power distribution room bus, or ring network cabinet, etc. the way. 6. T-connection refers to that there is no dedicated switch device (interval) at the distributed power access point. For example, the distributed power supply directly connects to overhead or cable lines.
