Summary: To ensure meeting the reliability goals of the Smart Grid, Demand Response programs are offered by electric power utilities with incentives to participating customers in order to match power generation to demand and prevent network instability during peak demand periods. According to the Energy Information Administration’s (EIA) 2012 commercial building energy consumption survey (CBECS), large office buildings in the USA with floor area > 9,000 m2 consume annually 180 billion kWh. This comprises of HVAC (cooling 17%, ventilation 25%), lighting (17%) and plug loads comprising of computers, monitors, printers, servers and other electrical loads associated with occupant productivity (17%) and the rest miscellaneous loads. These loads mostly occur, given the occupancy schedule, during the on-peak periods for a summer peaking utility. The need to address Automatic Fault Detection, Diagnosis and System Restoration (AFDDS) becomes important when implementing demand response (DR) strategies whether it is price responsive or resource responsive in office buildings. Should faults occur in the building HVAC system, the kWh energy consumption and KW demand will increase negating the objectives of the Demand Response program. This presentation will cover: definitions for Smart Building HVAC System; Smart Building Facility Management System (SBFMS) Architecture; development of algorithms for AFDDS for an example HVAC system with self-healing and resiliency feature and discuss the results of ‘Smart Voice Activated Speaker’ experiments with lighting and Plug loads and opportunities for its integration with SBFMS.

Summary: In recent years, Plugged-in Electric Vehicles (PEVs) have become more popular due to the growing interest in energy security and emission reduction. In addition to fulfilling these objectives, PEVs can play a crucial role in balancing the active power as well as compensating the reactive power of the smart power grid. These ancillary services provided by PEVs, not only help in improving the reliability and quality of the power, but also benefit the grid operators and PEV owners financially. In this talk, a PEV-based reactive power compensation and a novel phase-detector-based feedback control system is discussed. The effects of reactive power compensation on the battery’s State-Of-Charge (SOC) are investigated. Also, detailed analyses are carried out to assess the impacts of various components of a reactive power compensation circuit. Simulation results are provided to support the analysis and demonstrate the effectiveness of the proposed approach.

When determining relay settings, Protection Engineers use Isc data from short-circuit computer programs to obtain the current flowing through the system for various faults. The program can be directed to show the contribution of current by any element in the system and for any fault in the system. Mutually coupling data must be entered into the program for those lines installed close to each other to get the result of any coupling voltages and currents during fault conditions.

This presentation will explain the miss-operation of a mutually coupled 69 kV line to a 230kV line that occurred on December 23rd, 2013 in the San Diego Gas & Electric 230/ 69 kV system.

The actual misoperation was due to a wrong directional decision made by a microprocessor relay for a duration of 4ms before dropping out. By this time a trip and a transfer trip was given to the line, isolating it from the 69 kV systems.

This line was protected with Phase Distance and Ground Directional over-current primary relay and Phase and Ground Directional over-current back up relaying, on one terminal and with Phase and Ground Distance protection for the Primary relaying and Directional Phase and Ground over-current backup protection over Audio Tone communication channel. Settings for this line were done using our traditional 80-85 percent PUTT line reach with the traditional higher setting for the Instantaneous ground elements due to Mutual coupling.

The purpose of this presentation is to share with other Protection Engineers the knowledge and experience gained by the study of a utility relay misoperation and the solution used to fix this problem by introducing Negative Sequence Elements logic to increase security and sensitivity in the relay setting and also explains how to avoid future relay misoperations.

Summary: Non-orthogonal multiplexing (NOM) technology can provide significantly higher transmission capacity than the traditional orthogonal multiplexing (OM) technologies, when delivering multiple services with different quality of service (QoS) requirements. This has been recognized by research communities from both the broadcast industry and the mobile broadband industry.

The NOM technology can find many applications in future broadcast and broadband systems, including the simultaneous delivery of mobile and fixed services, seamless local content insertion, and delivery of mixed unicast-broadcast services in 4G/5G systems. A particular interesting new application scenario of NOM is recently developed to realize more efficient integrated broadcast service and backhaul (ISB) transmission, in both next generation ATSC 3.0 digital broadcast system and for 5G broadcasting system. This concept is directly related to the integrated access and backhaul (IAB) technology currently being studied for 5G NR.

This talk starts with the fundamental capacity benefit of NOM technology over OM technologies from the information theory point of view. Then, the different applications of NOM technology in future broadcast and broadband systems are introduced, including the benefit that NOM offers and the challenges to realize it in practice. General guidelines for achieving feasible implementation of NOM in practical systems are subsequently presented that keeps a low complexity and still achieve most of the NOM benefits.

As the second part of this lecture, the concept of using NOM to implement integrated service and backhaul links is introduced. First, the application of this concept in the next generation ATSC 3.0 is presented focusing on supporting low-power gap-fillers to improve the mobile service coverage performance for highly populated indoor and closed areas (airports, shopping malls, stadiums, etc.). Next, this concept is extended for integrated access and backhaul in 5G framework, where the focus is put on realizing a low-cost MBSFN over the low-power-low-tower broadband networks.

RSVP: requested, through website
Event Details: IEEE vTools

Summary: On July 4, 2012, the ATLAS and CMS experiments at CERN’s Large Hadron Collider (LHC) announced the discovery of the long sought-after Higgs boson. This was the culmination of a huge scientific endeavor involving theorists, detector, and machine physics and an army of engineers and technicians. ASICs played a significant role in the design and construction of the experiments and were one of the key enabling technologies permitting efficient particle detection in an extremely hostile environment. The presentation will start with a lay-person’s description of a large high-energy physics experiment and review some of the challenges presented for ASIC designers by the LHC environment. The talk will then focus on inner tracking detectors based on hybrid pixels. Such detectors provide the possibility of unambiguous (noise hit free) particle detection, an essential feature for disentangling complicated particle collisions taking place 40 million times per second. The same technology has been adapted for applications beyond high-energy physics in various generations of the Medipix and Timepix chips. That work has led to numerous novel applications stretching from particle detection in classrooms to recent ground-breaking results in spectroscopic medical X-ray imaging. Particle detection in real time will be demonstrated and a number of related applications described.

Bio: Michael Campbell is Head of the Microelectronics Section in the Experimental Physics Department at CERN in Geneva, Switzerland where he has worked for over 30 years. He was one of the pioneers of pixel detector readout and of the use of radiation-hard-by-design techniques both of which are now exploited widely in ASICs at the Large Hadron Collider experiments. He is spokesperson of the Medipix2, Medipix3 and Medipix4 Collaborations who seek to disseminate pixel detector technology to many different fields. Michael received his PhD from the University of Strathclyde, Glasgow, Scotland (his native city) and has authored several hundred scientific publications. In 2016, he was appointed Honorary Professor of the Department of Physics and Astronomy at the University of Glasgow.

Summary: Wireless technology is a shining example of a disruptive innovation that has changed society in remarkable ways. The innovation has altered how people communicate, how people access information, how people are entertained, and how people conduct and schedule their social lives. Every human activity advance and grows through several influences. One is experience, one is market forces, another is effective education, and yet another is common wisdom. Common wisdom is entrenched perspectives and levels of understanding accepted by the community as guide posts of the process. In fact, there are many examples to be found in the wireless community of common wisdom being faulty. Samuel Clemens’ comment “It ain’t what you don’t know that gets you in trouble, it’s what you know for sure that just ain’t so” The wireless community is not free of entrenched faulty common wisdom which is passed on to successive practitioners of the art. Universities are just as liable as industry for not examining and questioning common wisdom. In this tongue in cheek presentation we examine the evolution of wireless technology from the early days through now and show how several wisdoms can be shown to not be wise but never-the-less have become entrenched in the fabric of our wireless technology.
