Nowadays, technologies are rapidly developing, automation is omnipresent in our life. In the power system, automation technology solutions have been applied gradually and widely to meet the requirements of reliability. Before, when a fault occurs on the distribution network, the fault locating, isolating and grid restoring are still being done manually, so a large number of customers that are not in the fault zone still suffer outage for a long time. Distribution Automation System was developed to solve this problem. Currently, with the development of information technology, the Decentralized Loop Automation (DLA) in the distribution network is carried out by communication between the protective devices in the grid. Communication between devices can be done using time-control rules, using GOOSE messages, wifi or according to protocol IEC 61850. In addition, the protective devices can be connected to the control center to create a Centralized Loop Automation (CLA) in the distribution network. The paper considers the DLA solution with the time-control rules for a simple grid. Time-control rules models and simulation results were performed on MATLAB/ SIMULINK software. The paper proposed a user interface for DLA solution with many different failure cases, especially considering the protection coordination in case of doubles failure. The results of the paper show that DLA can isolate faults automatically and restore the grid in a short time, and these results can be developed as an experimental simulation in the future.

Service Restoration

Whena fault of the distribution network has occurred, it is necessary to pinpointthe type of the fault and its location and to isolation the fault by sectionswitches. It is then the task toattempts to restore service to as many unfaulted sections of the feeder aspossible via the available sources. Torestore feeder sections, the feeder must be bothering least one backup sourcewith sufficient capacity to bear the additional load. A method based on the backup feeder loadbalancing is proposed and software is developed. The service restores software obtains thedistribution operation data from distribution automation system (SCADA) and thefeeder parameters from power grid production management system (GPMS). Then compares that loads with the sparecapacity for backup sources and bring out the service restoration plan for thedispatch staff.

Power Restoration

The purpose of this paper is to propose a mixed integer programming model of service restoration reconfiguration considering the minimum switching frequency and power losses. The recovery after the service failure of distribution network is a multi-objective optimization problem with constraints. This paper also discusses the reconfiguration algorithms for power restoration and load balancing in the real-time operation environment of distribution network, which can make the problem solving easy to handle and control. The methods and measures for service auto restoration in distribution automation system are analyzed by examples.

Outage Analysis

Abstract People’s lives are becoming more and more inseparable from electricity, and the requirements for the quality of power supply are getting higher and higher. Because of most of the faults in the power system originate from the distribution network, the need to standardize the management of power outages and improve the efficiency of research and judgment has become more and more significant. However, in China, the differences in the development of automation construction in various places and the outage information of different departments require that power outage business applications should try to achieve accurate analysis of outage information under different scenarios. This paper designs a power outage analysis approach, which comprehensively analyzes distribution network data such as substations, lines, and meters, and establishes a signal credibility image, which flexibly mines and analyzes outage events from multiple dimensions and effectively improves the fault tolerance of fault location.
