摘要
输电线路的利用率是评价电网运行效率、指导电网规划的重要指标。提出基于时序分析法的输电线路利用率综合评估方法,通过输电线路利用率的概率分布特征评估输电线路的利用率。以4条典型220 kV输电线路为例,利用其SCADA实测数据综合分析了输电线路的利用率。算例分析表明,该方法能够较为全面地分析电网输电线路的利用率,对于完善电网规划具有指导意义。
The utilization rate of transmission lines is an important index to evaluate the operation efficiency of power grid,and guide the plan of future power systems. A time serial method is proposed in this paper to evaluate the utilization rate of transmission lines. The statistical distribution of the utilization rate is adopted to analyze the utilization of transmission lines.Four transmission lines are examined with field SCADA data to check their utilization rates. Examples show that the proposed method can evaluate the utilization of transmission lines efficiently, and results obtained are useful for plan.
