Research On Voltage Quality Problems Of Dalian Grid And Its Improvement Method

Nowadays, with the rapid economic development electricity has become a part of people’s daily lives. The stable operation of power system is very important to maintain daily life and society stability. The improvement of voltage quality have great significance to the safety operation of power grid and electrical equipment, protection of product quality and scientific experiments as well as people’s life and production. Voltage quality directly related to the national economy. To improve the quality of the grid voltage, the voltage of the grid should be collected and analyzed.This paper counts the electricity consumption and voltage quality of section 10kV substation of Dalian Ganjingzi region in 2014. And taking appropriate measures to improve the voltage quality by analysis of the statistical data. Distribution Automation System can reflect the electricity consumption of each user, stability of voltage and current, the operation status of each substation timely, providing the basis for power grids transformation, reducing energy emissions without affecting production, generalizing the safe and clean production development strategy, thus achieving efficient use and recycling of resources, namely the circular economy.
