摘要
针对配电网管理要求的不断提高,线损的准确计算越来越重要,因此,文章分别介绍等值电阻法、分相等值电阻法、电压损失率法3种计算方法,说明各算法优缺点,选取实际三相不平衡低压配电网作为案例,通过分析得到:在计算三相不平衡低压配电网负荷时,采用分相等值电阻法的计算结果最精确,可以提高供电公司的经济效益,具有一定的应用价值。
In response to the continuous improvement of requirements for distribution network management,accurate calculation of line loss is becoming increasingly important.Therefore,this article introduces three calculation methods:equivalent resistance method,split phase equivalent resistance method,and voltage loss rate method.An actual three-phase unbalanced low-voltage distribution network is selected as a case study.Through analysis,it is found that when calculating the load of three-phase unbalanced low-voltage distribution network,the calculation results using the sub item equivalent resistance method are the most accurate,which can improve the economic benefits of power supply companies and has certain application value.
