The power distribution network has grown complex and vulnerable as it increases its demand. The system's reliability has become a prominent factor for the end-users, although the continuity of supply in the distribution network still remains a challenge. In order to achieve the same distribution, automation came into the picture. The term “Distribution Automation” usually refers to an advanced switching system, which works as a subsystem of the existing network. The purpose of the subsystem is to offer real-time observation and control in distribution networks and electricity market operations. Consequently, the development of an autonomous system for isolating failures and restoring power for the distribution of LV (low voltage)/MV (medium voltage) can be an attractive solution for improving energy facilities' reliability. Advanced management techniques are devices and algorithms used to analyze, diagnose, and predict conditions in a distribution network, as well as to identify and take appropriate corrective actions to eliminate, mitigate, and prevent power outages and power quality problems. To demonstrate the model, we used a PIC16F877, CT microcontroller, and a power supply unit.

With the development of the smart grid technology, power distribution network puts forward a higher request for transmission bandwidth and reliability. First, we analyze the characteristics and the business needs of the distribution network. Then we analyze the distribution network communication technologies, both wired and wireless. Based on our analysis, we should combine various communication technologies according to the comprehensive economic and technical indexes in power distribution automation communication system.

Abstract On the basis of analyzing and summarizing the current situation of the construction and use of distribution automation systems at home and abroad, according to the requirements of the use of distribution automation systems, a data two-way interactive distribution automation system architecture design is proposed. In response to the requirements for multi-source data collection in the distribution network, a distribution automation system architecture with partitioned collection and bidirectional data flow is proposed to improve the perception of distribution network equipment. Propose the self-recognition technology of power distribution system and terminal based on IEC61968 and IEC61850 model mapping to realize the fast access of power distribution terminal. Propose a grid integration modeling and global decision analysis method based on model splicing technology to realize multi-dimensional data fusion and analysis applications.

As the basis of power distribution network automation, the feeder automation plays an important role in the distribution network. The traditional feeder automation system has a long fault isolation time, the frequent switching and outgoing and then overlap power filter troubleshooting repeatedly. 10 kv feeder automation system in the thesis is controlled by the upper PC computer system and the lower machine system, and the lower machine system's intelligent controller collects the operation information of the voltage and current of the line being monitored in real time with AC-sampling technology, and through the GPRS wireless communication network will field data is passed to the remote control center. When the short circuit faults occur, the controller will immediately disconnect the switch, and the incorrect information will be sent to the remote control center, the remote control center to collect incorrect information from all the controllers, then provide the fault judgment and control strategy through relevant logic. Practices have proved that the system could improve the level and reliability of power distribution network effectively.
