Voltage quality evaluation method for power distribution line of rural power grid

The invention belongs to the technical field of combination of load moment calculation and power flow analysis of a power distribution network, and relates to a voltage quality evaluation method for a power distribution line of a rural power grid. The voltage quality of each node in the power distribution network is analyzed by obtaining and analyzing related information data of a power distribution automation system and combining a load moment method, and improvement measures are provided for improving the voltage quality of the power distribution network; the dynamic change process of the voltage quality is reflected through the maximum value and the average value of the active load moment of the transformer area, and the limitation of a traditional static statistical method is broken through; the evaluation result provides a decision basis for voltage quality treatment and power distribution network investment transformation. 本发明属于负荷矩计算与配电网潮流分析相结合的技术领域，涉及一种农网配电线路电压质量评估方法。通过配电自动化系统相关信息数据的获取分析，结合负荷矩的方法分析配电网中
