Abstract
With the development of national economy, the demand for electricity from all walks of life has been gradually increased. People also put forward higher requests to the reliability of power supply. Feeder automation can quickly cut off the faulty line to ensure the safe and stable operation of the line. Under the sustainable development of modern society, people attach a great importance to all aspects of smart power grid construction, which is also significant for the smart grid distribution work. To ensure the reliable and high-quality power supply environment, the scientific and reasonable design and planning of power distribution automation system shall pay attention to arranging power distribution, and the appropriate feeder automation operation mode shall be selected. Only in this way can we ensure that the power outage is short once a fault happening in power grid system. At the same time, the line loss rate can be reduced, the efficiency of power supply can be raised, and issues in power equipment investment can be effectively treated. This paper mainly discusses the design and implementation of feeder automation, puts forward some practical application measures, and provides reference for the stable operation of feeder automation.
Highlights
The developing national economy has promoted the further development of power system modernization, and the continuous improvement and development of distribution network automation system have been the development trend of modern power enterprises
We can find the problem in recovery, processing and load of distribution network fault, which cannot adapt to the needs of the development of modern society
Secondary indexes Output value per unit of electricity B11 Power supply load net asset B12 Cost of the unit substation capacity B13 Load ratio of main transformer B14 Average outage time of users B15 Voltage deviation B16 One family one standard rate B17 Power consumption rate B18. This is the project evaluation index of distribution feeder automation in power enterprises in X city, from which we can find that when it comes to the popularization and application of feeder automation, people lay stress on the output value per unit of electricity, cost of the unit substation capacity, cost of unit capacity and load ratio of main transformer and regard them as important evaluation indexes, so as to create a stable supply space; while feeding system in distribution network operates, the corresponding fault state variables are all installed in the intelligent terminal unit
Summary
The developing national economy has promoted the further development of power system modernization, and the continuous improvement and development of distribution network automation system have been the development trend of modern power enterprises. The feeder automation and the combination of intelligent terminal can effectively measure the operation results of distribution network automation system. We can find the problem in recovery, processing and load of distribution network fault, which cannot adapt to the needs of the development of modern society. It is of great practical significance for the safe operation of feeder automation to discuss the design and implementation of feeder automation
