面向输电系统的潮流和网损分配研究

Research on power flow and power loss allocation for power transmission system

提出了一种系统化的输电系统潮流和损失分配方法。该方法基于基本电路理论、等效电流注入法和等效阻抗法。利用4个步骤用于跟踪每个发电机依次提供的电压、电流、功率流和损耗,该方法可以计算出各输电线的实际功率和无功功率及其来源和终点。每台发电机所产生的每一条线路的损耗分摊也可得到。测试结果表明,该方法能满足潮流方程、功率平衡方程和基本电路理论,在与以前的方法比较以证明所提出的方法的有效性。

This paper presents a systematic power flow and loss allocation method for transmission systems. The method was based on the basic circuit theory,the equivalent current injection method and the equivalent impedance method. Using four steps to track the voltage,current,power flow,and losses that each generator provides in turn,the method can calculate the actual and reactive power of each transmission line and its source and destination. Loss sharing for each circuit generated by each generator was also available. The test results show that this method can satisfy the power flow equation,power balance equation and basic circuit theory,and compare with the previous method to prove the effectiveness of the proposed method.
