Abstract：In recent years, with the steady development of national economy, especially under the stimulation policy of new countryside construction and “village appliances”, the voltage is lower than the demand of user at peak times. It brings a lot of inconvenience to the life of people. In order to solve the problem of the low voltage, this article firstly analyzes the main causes of low voltage. Secondly, it advances the measures for the corresponding causes to control the voltage. And then, this paper uses the PSCAD/EMTDC simulation software to establish the rural distribution network power supply model based on actual case, and it simulates the low voltage causes about the long power supply radius, big transmission line diameter, overloaded distribution transformer and the three-phase unbalanced load. Finally, it verifies the measures for the low voltage.
