Guide to Power Supply Testing with MaxBotixMaxBotix Inc
Whether you believe your power supply may be faulty or you are doing routine
testing, it is important to verify the performance. Issues with a power supply can
limit the performance of your equipment, and it even has the potential to damage
your fine electronics. Proper and regular power supply testing can help minimize
this risk.
An appropriate analyzer is used to test and troubleshoot the aircraft thermocouple system at the first indication of trouble, or during periodic maintenance checks.

Experiences with Real-Time Hardware-in-the-Loop SimulationLuigi Vanfretti
This paper summarizes the list of activities carried out in Smart Transmission System Laboratory (SmarTS-Lab) within the domain of Real-Time Power System Monitoring, Operation, Protection and Control using opaOpal-RT’s eMEGAsim Real-Time Simulators. The major projects carried out include real-time hardware-In-the-loop (RT-HIL) execution of Unitrol 1020 Excitation System from ABB. The performance of Excitation Control System is validated for both Automatic Voltage Regulator (Auto) and Field Current Regulator (Manual) modes. In addition the power system stabilization (PSS) capability of Unitrol 1020 is exploited by using it as RT-HIL to provide power oscillation damping in a 2-area 4-machine Kundur’s power system. In another project, Compact Reconfigurable I/O (cRIO) controllers from National Instrument are programmed in Labview as a phasor based power oscillation damping controller. This NI-cRIO takes the voltage and current phasor measurements from PMUs (which are executing as RT-HIL with Opal-RT) and outputs a power oscillation damping signal which is added in the controls of SVC (simulated in real-time) to provide power oscillation damping. Finally an Open Source SCADA is setup in the SmarTS-Lab using PMUs/protection relays from ABB and SEL. The integration of PMU measurements in the SCADA system is evaluated and the limitations are discussed. The presentation will include some results from PMU steady state compliance testing with Stand-Alone relay protection test sets and its limitation which drives a need for PMU compliance testing using real-time simulator (Opal-RT). Also the roadmap for real-time power system simulation in conjunction with communication network simulation using OPNET's System-in-the-Loop (SITL) package will be discussed.

Real-Time Hardware-in-the-Loop Testing of an Excitation Control System for Os...Luigi Vanfretti
Presentation at the IEEE PES General Meeting 2015.
A feature of an Excitation Control System (ECS) for synchronous generators is to enable power system stabilization by providing an additional input to the Automatic Voltage Regulator (AVR) for external stabilization signals. This paper explores this feature by externally generating stabilization signals which are fed as an analog input to a commercial ECS. This allows bypassing the built-in PSS function in the ECS and gives more freedom to the end-user to utilize custom stabilizer models. ABB’s Unitrol 1020 Excitation Control System is coupled with Opal-RT’s eMEGAsim Real-Time simulator to perform Hardware-in-the-Loop simulation of the ECS. The output of several stabilizer models is fed to the ABB’s Unitrol 1020 ECS as external power system stabilization signals to analyze their performance for small signal stability enhancement.

IRJET-CUK Converter Based PV Module for Excitation Ff Synchronous MachineIRJET Journal
Vishant G. Naik , Santosh Singh Negi"CUK Converter Based PV Module for Excitation Ff Synchronous Machine", International Research Journal of Engineering and Technology (IRJET), Volume2,issue-01 April 2015.e-ISSN:2395-0056, p-ISSN:2395-0072. www.irjet.net
Abstract
The unavailability of fossil fuel and increasing demand for energy has pushed us towards finding alternative source of energy. The solar energy can be used for excitation of synchronous machine as an alternative source of energy. Due to increasing efficiencies and decreasing cost of PV cells, various MPPT algorithms have been implemented. In this paper a Cuk converter has been used in order to achieve constant excitation voltage which is required for exciting field winding of synchronous machine. MATLAB software has been used for simulation of both solar cell and Cuk converter which are modeled using sim power system blocks.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
