Using Immersive Virtual Reality for Electrical Substation Training
ISBN: 978-989-8533-40-1 © 2015 USING IMMERSIVE VIRTUAL REALITY FOR ELECTRICAL SUBSTATION TRAINING Eduardo H. Tanaka1, Juliana A. Paludo1, Carlúcio S. Cordeiro1, Leonardo R. Domingues1, Edgar V. Gadbem1 and Adriana Euflausino2 Eldorado Research Institute1, CPFL2, Campinas, SP, Brazil ABSTRACT Usually, distribution electricians are called upon to solve technical problems found in electrical substations. In this project, we apply problem-based learning to a training program for electricians, with the help of a virtual reality environment that simulates a real substation. Using this virtual substation, users may safely practice maneuvers with varying degrees of complexity. To improve the user’s sense of immersion, interactive devices such as the Oculus Rift virtual reality headset are going to be adopted. The project’s stakeholders had a good impression of the device and believe that the proposed methodology will improve the training and effect positively the electricians’ performance, reducing accidents inside the substation area and decreasing the time required to reestablish the power supply after a failure. KEYWORDS Electrical Simulation, Immersive Virtual Reality, Interactive Devices, Problem-Based Learning, Training Staff. 1. INTRODUCTION The electric power system consists of power generation, transmission and distribution networks, and load consumption. The power generation is the origin of the electrical energy. A transmission network is composed by high-voltage power lines, which drive electric power from a generation station to a load center area, as they are usually far apart for long distances. A distribution system has medium and low voltage networks and conducts electrical energy from the transmission system to industrial, commercial and residential loads. -

Smart Grid Conceptual Model (Second Discussion DRAFT) October 12, 2018
Update of the NIST Smart Grid Conceptual Model (Second Discussion DRAFT) October 12, 2018 NIST Smart Grid Conceptual Model The NIST Smart Grid Conceptual Model describes the overall composition of electric grid systems and applications. It is meant to provide a high-level view of the system that can be understood by many stakeholders. Originally introduced in the 2010 publication of the first NIST Smart Grid Interoperability Framework, the Conceptual Model is updated with each Framework revision. The Smart Grid Conceptual Model update in this document (see Figure 1) reflects large increases in the number and types of distributed energy resources (DERs) used throughout the grid, the increasing importance and automation of distribution systems, and the role of service providers in the Distribution system. Smart Grid Conceptual Model Operations Service Provider Markets Distribution Transmission Customer Secure Communication Flows Electrical Flows Generation including DER Domain Source: DRAFT NIST Smart Grid Framework 4.0 `` Figure 1- DRAFT Updated NIST Smart Grid Conceptual Model The key concepts derived from the updated Conceptual Model remain broadly similar to those of previous editions. First, the roles and responsibilities for actors and equipment in the electrical grid are a function of the domain in which they are applied. Through this lens we understand that functions required of grid equipment will likely change depending on the grid context, or domain, in which it is used.1 Benefits associated with equipment, resource, or action will similarly vary with domain and other context. Second, the conceptual model reinforces the contrast between the growing complexity of information exchange necessary to operate the grid, and the relatively straightforward physical exchanges of energy that actually are the grid. -
A Comprehensive Review of Operation and Control, Maintenance and Lifespan Management, Grid Planning and Design, and Metering in Smart Grids
Review A Comprehensive Review of Operation and Control, Maintenance and Lifespan Management, Grid Planning and Design, and Metering in Smart Grids Luis Hernández-Callejo Department of Agricultural Engineering and Forestry, University of Valladolid (UVA), Soria 42004, Spain; [email protected]; Tel.: +34-975-129-213 Received: 24 March 2019; Accepted: 26 April 2019; Published: 29 April 2019 Abstract: New technological advances based on software, hardware and new materials must be implemented in smart grids. In addition, these advanced electrical grids must incorporate elements of artificial intelligence. Advances in software development must be complemented with the development of new hardware (power electronics and active distribution among others). The aforementioned must rely on the development of new materials and sensors, which should be integrated into the smart grid. Therefore, the four areas of research based on the technologies are: Operation and Control, Maintenance and Lifespan Management, Grid Planning and Design, and Metering. The review presents the algorithms, materials, devices and others paradigms applied to smart grids, classifying the works according to the four areas of research. This review has focused on the four fundamental pillars of smart grids, on the one hand, the need for more efficient operation and control, followed by advanced maintenance management, to continue planning and designing the new grids, and for conclude with the advanced measurement. As you will see in the article, new devices, new techniques, and future scenarios will make possible the transition from the current grid to the future smart grid. Keywords: smart grids; artificial intelligence; smart metering; distributed energy resources; operation and control; maintenance 1. -
Benchmarking and Control Indicators for Electrical Substation Projects
Benchmarking and Control Indicators for Electrical Substation Projects Submitted by: Justin R. Nettesheim A thesis submitted in partial fulfillment of the requirements for the degree of Master of Civil and Environmental Engineering (Construction Engineering Management Emphasis) at the UNIVERSITY OF WISCONSIN-MADISON Fall of 2015 i ABSTRACT It is estimated that over the next two decades nearly $880 billion will be spent to build and upgrade high-voltage and distribution electrical facilities, such as substations and power lines. A major contributor to this cost can be attributed to the industry’s large construction labor component, which can account for more than half of total expenditures. One way to improve labor cost efficiency is by establishing productivity benchmarking and control indicators for project performance. However, despite the size of this industry, there is general lack of published literature regarding labor control mechanisms in relation to constructing substation and transmission line projects. This paper establishes typical benchmark indicators by using comprehensive data tracked daily or weekly for 14 well-executed high-voltage electrical substation projects. The input data collected was limited to projects completed for owner in the upper Midwest by two different construction contractors. The data analysis from these inputs yielded initial manpower loading curves and S-curves trends for the typical labor associated with above- grade substation construction. In addition, the paper provides a percent breakdown of the typical labor hours per above-grade activity. The paper also provides practitioners with practical input for managing substation construction projects by providing examples of Work Breakdown Structure, timesheets, and productivity tracking. The typical benchmarking and control indicators presented in this paper are expected to aid substation practitioners better plan and track labor performance, and also provide a framework for future research into benchmarking and control indicators in this industry sector. -

Electrical Substation
Electrical substation A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Electric power may flow through several substations between generating plant and consumer, and its voltage may change in several steps. Substations may be owned and operated by a transmission or generation electrical utility, or may be owned by a large industrial or commercial customer. Generally substations are un-attended, relying on SCADA for remote supervision and control. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages. The word substation comes from the days before the distribution system became a grid. As central generation stations became larger, smaller generating plants were converted to distribution stations, receiving their energy supply from a larger plant instead of using their own generators. The first substations were connected to only one power station, where the generators were housed, and were subsidiaries of that power station. Elements of a substation Substations generally have switching, protection and control equipment, and transformers. In a large substation, circuit breakers are used to interrupt any short circuits or overload currents that may occur on the network. Smaller distribution stations may use recloser circuit breakers or fuses for protection of distribution circuits. Substations themselves do not usually have generators, although a power plant may have a substation nearby. Other devices such as capacitors and voltage regulators may also be located at a substation.
