Cascaded on-load tap changers (OLTC) are widely used for coarse voltage control in electric power systems. There could be an interaction between load dynamics and OLTC control under certain system operating conditions which may lead to OLTC limit cycle phenomena thereby resulting into long term voltage oscillations in the system. In the recent years, renewable and non-renewable local generation units have been getting interconnected in modern power systems. The existence of OLTC limit cycles in the presence of local generation units has not been addressed thoroughly in the literature. In this paper, the OLTC limit cycle phenomena, which can occur due to interactions among load-voltage dynamics, OLTC controls and the local generation, has been investigated. Also, a strategy is proposed for mitigating the power system oscillations which can be induced by OLTC limit cycles, especially with local generation units in the network. The proposed mitigation strategy including detailed investigations and analyses have been verified for a two-bus system, and successfully tested on a multi-bus system with local generation units using MATLAB.

In this paper, two modulation strategies for a three level neutral point clamped inverter SynRM drive are compared. The inverter uses two different algorithms called Mod-1 and Mod-2 for balancing the two dc bus capacitor voltages (suppression of the neutral point voltage). These modulation strategies are of the nearest three vector (NTV) family. Mod-1 chooses certain vector states to suppress the neutral point (NP) voltage ripple, whereas Mod-2 makes use of the inverter vector state's dwell time. The parameters of interest are the torque ripple, the neutral point voltage ripple and the inverter efficiency. The inverter was operated at a switching frequency of 10 kHz. The SynRM core losses were independent of the two modulation strategies, though lower torque ripples and better power quality were registered on Mod-2 strategy. Mod-1 strategy had 18% higher inverter efficiency during transient operation. Mod-2 strategy had 11% more NP voltage ripple during transient operation. The Mod-1 strategy supressed the NP voltage ripple throughout the machine's operation.

Space charge measurement techniques are widely used to characterize dielectrics. There are several methods : some are destructive, some others are non-destructive (i.e., they neither degrade the materials mechanically nor alter their electrical state). This paper is dedicated to the description and the feasibility of a non destructive contact-less method to measure space charges. This contact-less method is based on standard Thermal Step Method and allows space charge measurements under electrical stress, keeping the non destructive property of the original method.

Notwithstanding massive fire safety campaigns being carried out, incidents of fire outbreaks continue to increase annually. The alarming rate of these fire outbreaks requires an engineered solution system that detects fire in its early stages and contributes to the firefighting effort. Current research efforts have been directed towards the development of multi-sensor fire detection algorithms to increase the sensitivity of fire detection devices and reduce nuisance alarms. This paper presents the design and implementation of a multi-sensor fire detection and notification system using fuzzy logic. The microcontroller processes data from an MQ2 smoke sensor, a TMP102 temperature sensor and a DFRobot flame sensor using a fuzzy logic algorithm to determine the fire status.

We have been investigating a technology for decomposing adsorbed volatile organic compounds (VOCs) using a nonthermal plasma flow, which is easily generated at low cost with a compact apparatus. In this study, we investigated the effect of water spray on the decomposition of adsorbed toluene that is achieved using nonthermal plasma flow. Spraying water upstream of the adsorbent should increase the amount of OH radicals, which form a strong oxidizing agent, and thereby enhance the toluene oxidation. Two different water spray conditions are tested: (I) spraying for 10 s after 30 min, spraying for 20 s after 60 min, and spraying for 10 s every 3 min from 90 min to 120 min; and (II) spraying for 10 s every 5 min. The decomposition efficiencies under conditions I and II are compared to that achieved without water spray. With no water spray and under condition I, the toluene conversion efficiency reaches a maximum of 98% in 105 min after the experiment starts. In contrast, the conversion efficiency is 76% under condition II. Excessive humidity is known to decrease ozone generation; therefore, the conversion efficiency decreases.

This paper documents the design and development effort for constructing a multi-megawatt mechanical and electrical test facility for renewable energy research. The mechanical test platforms are specifically designed to explore the machine dynamics of wind turbine nacelles. The electrical test areas can be interconnected with the mechanical platforms to facilitate complete mechanical and electrical evaluation of wind turbine performance related to grid code requirements, or can be operated independently as multi-megawatt test bays for testing and model verification of other devices.

Tribo-electrostatic separation of mm-size granular plastics mixtures is widely used in recycling industry. However, electrostatic separation of micronized plastics is still inefficient since the adhesion and aerodynamic forces surpass the electric force. The aim of this paper is to optimize a new separation process for mixed fine granular plastics based on a fluidized bed tribocharging system. A pair of opposite high voltage parallel plate electrodes are immersed in that bed and undergo a vertical alternating movement. The fine PVC particles of average size 0.1 mm particles to be separated are tribocharged using a fluidization air provided by a variable-speed blower. The charged particles are pinned to the electrodes of opposite polarities. The separation depends on several factors: the electric field, the speed of the electrode movement, the mass of the granular product and the fluidization rate. This latter was the most significant factor and the interval between the electrodes should not be less than 2 cm to avoid corona discharge.

Proposed are new applications of image displays to invisible optoelectronic watermarking systems whose technique will be effective in business and industry. The system is basically characterized by paired installer and viewer of new kind to transfer hidden invisible auxiliary data on watermark code patterns. A flat-panel image display enabled us to demonstrate invisible data hidden behind the watermark codes embedded into object image data by use of the installer. Smart devices placed against the flat panel displays enabled us to establish an optical link between them in a variation of the system for taking out and reading the watermark codes by use of the viewer. So, each smart device could also be used to resume original auxiliary data on the small display attached to the viewer. This kind of optoelectronic system established with a smart device was experimentally confirmed to be applied to business and industry by transferring alphanumeric characters stably.

This paper investigates the design of a medium voltage direct current (MVDC) microgrid for a remote area mine site. The various aspects covered include its protection schemes as well as operation and control. This is intended to provide a voltage of high power quality and reliability at the sensitive load terminals, and also improve the energy efficiency of all the mining equipment. In the proposed MVDC microgrid, several local distributed energy resources (DERs) have been employed including PV arrays, wind turbines, a fuel cell stack, an energy storage system and mobile diesel generators. A comprehensive analysis is presented on the protection, operation and control of the MVDC microgrid system. A communication based differential protection scheme with solid state electronic relays is employed for isolating only the faulted portion of the MVDC microgrid. Previous research work had largely neglected the backup protection for DC systems. In this paper, the overcurrent protection device is utilized for backup protection. Furthermore, with an appropriate communication and cooperative framework among these DERs accompanied by dc bus signaling (DBS) control, the dc bus voltage can be maintained within an acceptable range. MATLAB/Simulink modeling and simulation results are presented and discussed to illustrate the system's reliability, security and power quality.
