Substation automation research frontiers

Abstract

Substation automation has critical role in power systems. Substations are responsible for many protection, control and monitoring functions that allow robust routing of power from generators to loads through a complex network of transmission lines. With the latest technology development many intelligent electronic devices (IEDs) available in substations today are capable of performing enhanced functionalities beyond what their basic function is. This brings an opportunity for adding new functionalities that go well beyond what the traditional substation automation solutions have provided. This panel presentation summarizes university research undertaken through collaboration between industry, EPRI, DOE and NSF's Power Engineering Research Centre consortium. Projects focused on implementing a new concept for merging operational and nonoperational data are introduced. They are aimed at expanding the substation automation role towards better serving many utility groups: operations, protection and asset management.Index Terms-substation automation, expert system, fault location, genetic algorithm, intelligent electronic device, neural network, power system monitoring, substation measurement, sampling synchronization, asset management, alarm processing.

Environment Understanding Algorithm for Substation Inspection Robot Based on Improved DeepLab V3+

“…The substation, one of the important components of the power grid, is also the basis for measuring and controlling the power grid [ 1 , 2 ] and is responsible for the regulation of voltage rise and fall and the distribution of electrical energy in the power network. In order to ensure the normal operation of the substation, it is necessary to conduct regular inspection of the operation state of the power equipment in the substation, so as to eliminate the power security risks in an early and timely manner [ 3 , 4 , 5 ].…”

Monitoring and Controlling Services for Electrical Distribution Systems Based on the IEC 61850 Standard

“…Consequently, automation of power distribution systems has increasingly been adopted by power utilities worldwide in recent years as part of their efforts to pro-vide a more reliable supply to its customers and to enhance operational efficiency. Thus, the principal objective of electric system automation is to respond rapidly to real time events with pre-specified actions in order to maintain uninterrupted power service [2].…”
