摘　　要：为了提高线路的电力输送能力,确定最优功率调整节点,进而控制短时过负荷,提出了低功耗状态下的架空线路短时短时过负荷能力确认算法。分析各节点功率变化量与线路功率变量的关系,以最低功率调整成本作为目标函数,并将有功调整功率最低作为约束条件,控制架空线路短时过负荷,确认过负荷能力。实验结果表明:架空线路应用JL/G1A-400/35导线可具有更长的短时过负荷时间,有利于短时过负荷的有效控制。该方法可确定最优功率调整节点、并以最低功率调整量实现短时过负荷的控制,且控制成本最低。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 experimental 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 realize the control of short-time overload with the lowest power adjustment,and the control cost is the lowest.
