In order to solve the problem of inaccurate and unreasonable capacity control quota of 10 kV line access distribution in the existing distribution network

which can not be differentiated according to the local actual situation

this paper combs the load operation data of distribution in a city in recent 6 years

analyzes the factors affecting the line load capacity

establishes the calculation formula of 10 kV line access distribution capacity

and calculates the average demand coefficient of typical distribution load. At the same time

the paper formulates the capacity control limit of 10 kV line access distribution transformer under different load development stages

different load properties

different 10 kV line target connection modes and power supply capacity.
