    THE MARKET FOR INTEGRATED power systems for more electric aircrafts and, in particular, for unmanned air vehicles (UAVs) is rapidly developing [1]. Due to space constraints, a practical solution for UAVs is to employ electric-starter generators (ESGs) embedded in gas turbine engines to facilitate electric engine crank, assist the engine in reaching the desired idle speed, generate power to drive the onboard auxiliaries, and improve the overall efficiency of the system [2]. To control the ESG, a position sensor is required for the closed-loop control of speed and torque. However, the traditional sensors that provide accurate knowledge of the machine rotor position to facilitate precise control of the ESG cannot be used because of adverse operating conditions.

    When inverters in voltage control mode are paired with synchronous generators (SGs), they exhibit poor transient load sharing in islanded operation. It is well known that power electronics respond more quickly where the inverter initially picks up the majority of every load step, and the generator's output slowly increases until they reach their steady-state load sharing given by droop settings. This excessive transient power output from the inverter constrains its rating relative to the largest load step and could negatively impact the battery life in battery energy-storage inverters. This article provides a detailed examination of the differences between the frequency-regulation characteristics of inverters and generators to explain, in a novel way, the cause of the poor transient power sharing. The tradeoff between an improved transient load sharing and increased voltage and frequency transients is highlighted, and it is demonstrated that equal transient load sharing can be achieved by emulating an SG using a power hardware-in-the-loop (HIL) approach. Validation is provided by simulation and experimental results. View full abstract»

  • Optimizing Steel Coil Production: An Enhanced Inspection System Based on Anomaly Detection Techniques

    Endless strip generation is the key to productivity and quality in several types of steel coil production lines. Coil-tocoil joining by means of welding machines provides such a strip. Since the joint is the weakest area of the strip, its quality must be assessed for the production line to accept it. Therefore, it is necessary to inspect the quality of the weld in the welding-cycle time. Based on our knowledge acquired in the previous development of quality assessment prototypes for steel strips, we present in this article an improved inspection system to detect defective resistance seam welds based on anomaly detection techniques. This system does not rely on the weld classifications done in production lines based on welding control programs. Therefore, it is immune to the influence of both incorrectly configured welding control programs and chemical composition variations from coil to coil of the same steel grade. Tuning the inspection system required a fully experimental design, which would have taken several months using a conventional computer. For this reason, the high-performance computing (HPC) facilities at the Edinburgh Parallel Computing Center were used to cut down the tuning time. View full abstract»

    Flexibility in the control of electric power generation within an industrial facility can be improved through the implementation of technology associated with recent advances in electrical system measurement techniques and communication protocols. Although generator speed governing and synchronization technology has remained relatively static in recent years, advancements in generator control, including the ability to eliminate the need for stand-alone bus synchronization systems, are described in this article. For such advanced systems, time-synchronized measurement and the control of generators are required, using technology such as IEEE C37.118 (synchronized phasor measurements) [1]. Time-synchronized measurements implemented in each generator governor controller allow for the precise control of a power system island or group of islands relative to each other or to a master reference. Accordingly, independent, perpetually synchronized power system islands were tested in a laboratory using time-synchronized governor controllers. The results are documented, and conclusions are drawn regarding the feasibility and usefulness of such technology. Additionally, challenges related to control and synchronization difficulties faced at a variety of industrial facilities are discussed as well as how this new control technology can help overcome such difficulties.

  • Managing Industrial Energy Intelligently: Demand Response Scheme

    Electric demand-side management (DSM) focuses on changing the electricity consumption patterns of end-use customers through improving energy efficiency and optimizing the allocation of power. Demand response (DR ) is a DSM solution that targets residential, commercial, and industrial customers and is developed for demand reduction or demand shifting at a specific time for a specific duration. In the absence of on-site generation or the possibility of demand shifting, the consumption level needs to be lowered. While the noncriticality of loads at the residential and commercial levels allows for demand reduction with relative ease, demand reduction of industrial processes requires a more sophisticated solution. Production constraints, inventory constraints, maintenance schedules, and crew management are some of the many factors that have to be considered before one or more processes can be temporarily shut down. An intelligent system is designed in this article for implementation of DR at an industrial site. Based on the various operational constraints of the industrial process, it determines the loads that could be potentially curtailed. Fuzzy/expert systems are used to derive a priority factor for different candidate loads. This information can then be used by the plant operator/DR client to make a comply/opt out decision during a utility-initiated DR event. View full abstract»

  • Paper Machine Dryer Section Tuning: A Novel Solution to Prevent System Instability

    Paper machine dryer sect ions create challenges in tuning due to gear backlash. This problem is amplified when older paper machines are upgraded with newer, higher-performance drive systems. The newer drive systems can achieve a much higher degree of control, which can fatigue the mechanical drivetrain. Most often, backlash is experienced during the speed regulator tune-up [1]. The speed regulator response is modified in an effort to improve stability while in backlash. However, there are other tune-up considerations that must be considered. A dryer section can be pulled from a downstream section, which can cause its applied torque to be near zero, resulting in speed instability. This article investigates the cause of this instability and presents a novel solution for preventing it. View full abstract»

    Researchers at the National Institute for Occupational Safety and Health (NIOSH) are developing an intelligent machine guard monitoring and proximity detection system designed to mitigate machine entanglement and maintenance-related injuries and fatalities prevalent in the mining industry. This experiment was designed to develop a monitoring system consisting of mechanical/magnetic switches and sensor beacons capable of wirelessly transmitting information about a belt conveyor's machine guards to a remote computer. The data transfer was carried out via an off-the-shelf wireless communication system and displayed on a Web-based user interface. Successful operational tests demonstrated the functionality and effectiveness of the system in monitoring guard placement status and remotely identifying the location of any removed guards using each sensor's unique identification number. The integration of wireless safety technologies such as this system is expected to improve the safety of miners by providing additional protections against machine guardingrelated injuries.
