Distribution Network Automation Technology based on Low-voltage Intelligent Switch

With the continuous progress of social economy, the shortage of electric power is becoming increasingly severe. At this time, the development of smart grids is extremely important. At present, permanent fixed equipment is used for online monitoring and load control of each main power supply terminal. However, the dedicated power quality monitoring and load control equipment is very cost-effective and has limited monitoring effects. In order to study a method that can reduce power loss and improve the efficiency of distribution network automation, at the same time, in response to the needs of the construction and development of smart distribution networks, a distribution network automation technology based on low-voltage smart switches is proposed. In the experiment, the relevant content of the low-voltage smart switch is introduced, and the mathematical model is established during the analysis of the distribution network automation technology. At the same time, the changes of the supply voltage deviation, voltage fluctuation and flicker, and three-phase voltage unbalance are numerically calculated. . The design principles and performance of low-voltage distribution switches are explained in the design of the system, so as to analyze the importance and feasibility of distribution network automation technology based on low-voltage smart switches in the field of distribution network technology. The experimental results show that the distribution network automation technology based on low-voltage smart switches can reduce the maximum interruption time, the minimum interruption interval time, and the total interruption time of each load by nearly 10% which improves the utilization rate of electricity.
