In order to improve the power transmission capacity of overhead lines,determine the optimal power adjustment node,and then control short-term overload,a short-and short-term overload capacity verification algorithm for overhead lines under low power consumption is proposed.The relationship between the power variation of each node and the line power variable is analyzed.The minimum power adjustment cost is taken as the objective function,and the minimum active power adjustment is taken as the constraint condition to control the short-term overload of overhead lines and confirm the overload capacity.The ex-perimental results show that JL/G1A-400/35 conductor can have a longer short-time overload time for overhead lines,which is conducive to the effective control of short-time overload.This method can determine the optimal power adjustment node and re-alize the control of short-time overload with the lowest power adjustment,and the control cost is the lowest.
