Abstract: An electrical substation is a major and vital part where electrical power is transmitted to major and minor consumers. To ensure safety and reliability of the substation it is essential to borrow the principles of automation. The current architecture of substation automation contains various devices such as Digital Protective Relays (DPRs), Digital Fault Recorders (DFRs), PQ Meters (PQMs), Intelligent Electronic Devices (IEDs) and Supervisory Control And Data Acquisition system (SCADA). The Intelligent Electronic Devices (IEDs) perform various operations like control and record valuable information of both operational and nonoperational data. Amongst the installed IEDs, several problems emerged. The most important problem is lack of data verification in both analog and digital data's. This led to serious errors in substation operations. Understanding current statuses of substation equipments (such as circuit breakers), load flows, location and type of faults can be very difficult with unmatched sets of data. The SCADA system offers only open loop operation, thus it does not have continuous control over operations. This dissertation aimed at proposing a way of replacing the functions of IEDs through LabVIEW eliminating the disadvantages of lack of data verification and open loop operation. LabVIEW is a more versatile tool that can be modified whenever necessary and can be integrated with graphical user interface.

TL;DR: A common format for data files and exchange medium used for the interchange of various types of fault, test, or simulation data for electrical power systems is defined.
Abstract: A common format for data files and exchange medium used for the interchange of various types of fault, test, or simulation data for electrical power systems is defined. Sources of transient data are described, and the case of diskettes as an exchange medium is recommended. Issues of sampling rates, filters, and sample rate conversions for transient data being exchanged are discussed. Files for data exchange are specified, as is the organization of the data. A sample file is given.

Abstract: The advent of power industry deregulation has placed greater emphasis on the availability of information, the analysis of this information, and the subsequent decision-making to optimize system operation in a competitive environment. Intelligent electronic devices (IEDs) being implemented in substations contain valuable information, both operational and nonoperational, needed by many user groups within the utility. The challenge facing utilities is determining a standard integration architecture that meets the utility's specific needs, can extract the desired operational and nonoperational information, and deliver this information to the users who have applications to analyze the information. This article provides an overview of substation integration and automation fundamentals and focuses on best practices.
