Research on Low Voltage Control Measures of distribution Network

distribution network voltage is the main index of power quality, which has a direct impact on the safety and stability of distribution network and the safe operation of power equipment, power loss of transmission lines, industrial and agricultural safety production and people's daily electricity consumption. Based on the PSASP simulation software, the real-time simulation analysis of the voltage in the Nailin area is carried out. During the irrigation period, the simulation results show that the low voltage problem is serious, and the daily load fluctuation is obvious, so it is necessary to adopt the control measures which can adjust the voltage in both directions flexibly. After comparison, the line voltage regulator and SVG are proposed to be used. After low voltage control, the simulation results show that the low voltage problem is obviously improved . Finally, the management measures to improve the low voltage problem are put forward.
