    Abstract: Introduction was made to the serious low-voltage issues happened in Jihe line of city grid. This paper analyzed the mechanism and the main factors of low-voltage issues, listed the feasible solutions and focused on researching the feasibility of series compensation capacitor scheme. According to the reason leading to the low-voltage issues in Jihe line and the physical truth of city grid operation, this paper presented three-stage project treatment scheme of near term, medium term and long term. The best way to solve the low-voltage problem in remote rural area, which is beneficial to the ongoing project of power quality improvement of the rural distribution networks, is also proposed.
    Key words: distribution network; low-voltages; voltage regulator; improvement
