When evaluating power quality, voltage is a critical influencing factor. Voltage quality is typically assessed by measuring voltage deviation, fluctuation, waveform distortion, and three-phase symmetry—with voltage deviation being the most important indicator. To ensure high voltage quality, voltage regulation is generally required. Currently, the most widely used and effective method for voltage regulation involves adjusting the tap changer of power transformers.This paper primarily integrates

Long-Distance Power Line Distribution: Low Voltage and Large Voltage FluctuationsAccording to the "Technical Guidelines for Distribution Network Planning and Design" (Q/GDW 1738–2012), the supply radius of a 10 kV distribution line must meet the voltage quality requirements at the line’s end. In principle, the supply radius in rural areas should not exceed 15 km. However, in some rural regions, the actual supply radius may extend beyond 50 km due to low load density, small and widely dispersed e
