    ABSTRACT: In this article, a new basic unit for cascaded multi-level inverter is proposed. This inverter is able to increase the number of output voltage levels and reduces the number of power electronic devices. To generate all voltage levels at the output, five different algorithms to determine the magnitude of DC voltage sources are suggested. This inverter is compared with conventional cascaded multi-level inverters. The comparisons show that the proposed topology needs fewer DC voltage sources and power switches, less variety of the magnitude of DC voltage sources, and smaller amounts of blocked voltage by switches. As a result, the installation space and total cost of the inverter decrease. As it is impossible to use charge balance control methods for the asymmetric cascaded multi-level inverters, the developed topology based on the proposed cascaded inverter-the sub-symmetric topology with the usability of charge balance control methods-is proposed. A new algorithm is proposed to determine the magnitude of DC voltage sources. In addition, full-wave and half-wave charge balance control methods are applied in the proposed developed topology. The accurate performance of the proposed topology by applying charge balance control methods is verified through the simulation and experimental results of an 81-level sub-symmetric inverter.

    ABSTRACT: This article proposes power quality improvement in a three-phase AC mains-fed telecommunication power supply by using an improved power quality converter. Conventional telecommunication tower power supplies suffer from power quality problems, such as high input current harmonic distortion, low power factor, and voltage distortions at the utility interface. To mitigate these problems, modern AC-DC converters with power factor correction circuits are used at the utility interface. An integrated boost converter is used as a power factor corrector with an isolated DC-DC converter at the load end to form the proposed telecommunication power supply. The power factor correction converter mitigates the harmonic contents of the AC mains current and improves the power factor, whereas the isolated converter provides regulated load voltage and isolation. Voltage control is used for regulating the DC voltage of the isolated converter, while the power factor correction integrated boost converter employs a current control loop to shape input current to sinusoidal in-phase with voltage. The design, modeling, and simulation results are presented to demonstrate the effectiveness of the power supply at various AC mains voltages and loads. A prototype of the front-end converter is developed, and recorded test results are presented here to validate the simulated performance.

    ABSTRACT: In road transportation system, differential plays an important role of preventing the vehicle from slipping on curved tracks. In practice mechanical differentials are used, but they are bulky by increased weight. Moreover not suitable for electric vehicles especially those employing separate drives for both the rear wheels. Recently, the electronic differential constitutes technological advances in electric vehicle design enabling with better stability and control of the vehicle on curved roads. This paper articulate the modelling and simulation of an electronic differential employing a novel wavelet transform (WT) controller for two brushless DC (BLDC) motors ensuring the drive of two back driving right- and left-wheels. Further, the proposed work uses discrete wavelet transform (DWT) controller to decompose the error between actual and command speed provided by the electronic differential based on throttle and steering angle as the input into frequency components. By scaling these frequency components by their respective gains, obtained control signal which is actually given as input to the motor. To verify the proposal, a set of designed strategies were carried in particular, vehicle on a straight, turning right and left on road. Numerical simulation test results of the controllers are presented and compared for its robust performances and stability.

    ABSTRACT: A novel control algorithm devoted to remove undesired low-order current harmonics in AC motor drives is presented in this article. The proposed control algorithm combines a suitable multiple reference frame synchronous harmonic estimator and multiple reference frame vector control implementation to suppress the undesired harmonics contained in the motor stator currents. This control technique can handle positive-, negative-, and zero-sequence sets, keeping a satisfying dynamic behavior. The control technique has been evaluated by numerical simulations and experimentally tested on a permanent magnet synchronous motor drive.

    ABSTRACT: This article discusses the potential for identifying faulted segment(s) on multi-phase distribution primaries using sequence component modeling and standard three-phase short-circuit solvers. Identifying faulted segments in a timely manner speeds up fault isolation and restoration processes, contributing to greater feeder reliability. The methodology utilizes fundamental frequency current magnitudes from the feeder head in conjunction with an approximate sequence model of the multi-phase feeder including single-phase and double-phase line segments augmented with dummy lines. Under certain fault conditions, multiple faulted segments may be yielded for which a new faulted segment reduction method based on voltage sag data is proposed. The Saskpower network simulated in MATLAB/Simulink (The MathWorks, Natick, Massachusetts, USA) environment was used to evaluate the faulted segment identification and reduction methods. The evaluation studies show quite promising results in uniquely identifying the actual faulted segment with reduced measurement and modeling requirements. 2016

    ABSTRACT: Due to the increased penetration of distributed generations in distribution systems, transient stability is one of the major concerns to be analyzed. This article presents a support vector machine based approach for transient stability detection using post-disturbance signals extracted from the optimally located distributed generations in a distribution system having distributed generation. Initially, distributed generations are placed optimally, and their optimal sizes are found with objectives of loss reduction and reliability improvement for various distributed generation penetration levels, system configurations, and system loading conditions. Various asymmetrical and symmetrical faults at different locations in the system are simulated to calculate the critical clearing times. The post-disturbance values of terminal voltage, active power, reactive power, and speed obtained from the distributed generations for both stable and unstable cases are used as input features of the support vector machine for finding the transient stability status. The dynamic simulations are carried out on IEEE 33-node and IEEE 69-node radial distribution test systems with four distributed generations, modeled in DIgSILENT power factory software (DIgSILENT GmbH, Germany). The proposed support vector machine based approach predicts the post-disturbance transient stability of the distribution system accurately. 2016

    ABSTRACT: In view of fault resistance to the influence of distance protection, a new adaptive distance protection scheme for a transmission line is proposed in this article. First, according to the geometric distribution of the measured phasors in fault conditions, the voltage drop equation is established and the adaptive setting coefficient is defined. On this basis, the angular difference between the fault current and the measured current is calculated according to the negative-sequence and zero-sequence components of the current. Finally, a new adaptive distance protection criterion is established. Simulation tests on the real-time digital simulator 500-kV two-machine system verify that the proposed method is able to modify the protection setting value adaptively on-line, and it is applicable to various fault types with strong immunity to the fault resistance. It is also simple in formation and easy to implement. 2016

    ABSTRACT: This article proposes a differential search algorithm to solve a distribution system reliability optimization problem. Optimum failure rate and repair time of different distributor segments of a distribution network have been calculated to enhance reliability of radial distribution system, both without distributed generation and incorporating distributed generation as standby unit. The differential search algorithm, a recently developed optimization algorithm having improved exploration and exploitation ability, has been implemented to solve the reliability optimization problem in search for superior quality solution. The differential search algorithm mimics the Brownian-like random-walk movement used by an organism for its migration. Simulation results establish that the proposed approach outperforms other existing optimization techniques in terms of quality of solution obtained and computational efficiency as applied to optimize failure rate and repair time of a radial distribution network. 2016

    ABSTRACT: In this article, an analytical method to calculate the steady-state temperature distribution along the joint of a three-phase distribution cable is presented. The results of this method are compared with those obtained by an experimental study and by the finite-element method. It is found that the results of the analytical method are in good agreement with those obtained by an experimental study and by the finite-element method. The effects of connector dimensions as well as the effect of the ambient temperature and cable load current on the maximum temperature of the joint are discussed in detail. From the present analysis, it is found that the increasing of the connector length is more effective than the connector thickness in the reduction of the maximum temperature of conductor inside the joint. 2016

    ABSTRACT: In this article, artificial cuckoo search algorithm for optimal tuning of proportional integral (PI) controllers for load frequency control is introduced. To robustly tune the parameters of controllers, a time-domain based objective function is formed that is treated by the cuckoo search algorithm. A three-area system is investigated under different loading conditions to verify the effectiveness of the proposed algorithm. Simulation results are presented to prove the improved behavior of the suggested cuckoo search based controllers compared with a genetic algorithm, particle swarm optimization and a conventional integral controller. These results show that the developed controllers present better performance over other algorithms in terms of settling times and different indices. 2015

    ABSTRACT: Transformers are critical components in power systems and their failure can cause long interruption of power supply. The condition of a transformer can be monitored by performing thermal analysis. The use of non-linear devices, such as rectifiers and converters, draws harmonic currents that increase losses in transformers, thereby increasing their operating temperature. In this article, a new numerical approach is presented for determining the rise in hot spot temperature in a 5-kVA, 400/400-V dry-type three-phase transformer laboratory prototype. The key novelty is that the additional winding eddy current loss due to non-linear loads is considered in the numerical modeling. The winding eddy current loss corresponding to harmonic distortion is estimated by conducting experiments and calculations. Numerical simulations are carried out for a wide range of non-linear loads using a commercial computational fluid dynamics package, FLUENT 6.3. The proposed numerical methodology is validated by performing experiments on the transformer for possible non-linear loads and comparing the measured hot spot temperature with the simulated values. Correlation equations for rise in hot spot temperature as a function of total harmonic distortion are presented, which can be used for estimating the life of transformers when connected to different types of loads.

    ABSTRACT: Single-phase inverters employ LC filters for the purpose of reducing pulse-width modulation harmonics. The drawback of LC filter is its stability problem at resonance frequency. Passive damping offers simple and reliable solution, but it decreases the overall system efficiency. Active damping is lossless and provides flexibility of controlling the damping performance; however, it is sensitive to parameters variation. This article presents stability analysis of a single-phase full-bridge inverter to improve dynamic performance and stability. Design of LC filter is carried out considering both undamped and damped structures. The effect of filter parameters on pole-zero locations of the inverter is presented, and variation of the phase margin over a wide range of parameters variation is examined. Active damping using closed-loop current control of the full-bridge inverter to mitigate the resonance oscillation is designed and compared with passive damping. The disturbance rejection via dynamic stiffness with and without active damping is examined to justify the proposed current controller. Simulation and experimental results are presented to validate the effectiveness of the proposed design. It is found that the proposed control of the inverter provides excellent voltage regulation with low total harmonic distortion and ensures good performance and robust stability under parameters variation.

    ABSTRACT: A day dispatch strategy for the integrated system (IS) of wind/photovoltaic/pumped-storage/gas-turbine-power/energy-storage plant is proposed in this paper based on the time-frequency scales of power of wind/photovoltaic (PWP). Based on the day-ahead dispatch strategy, the day dispatch optimization model of the IS is first established, and then according to the patulous short-time prediction (PSP) and ultra-short-time prediction (UP) of PWP, the day rolling and real-time scheduling strategies are put forward based on the time-frequency scales of PWP. Finally, the cone programming method is applied to optimize the day dispatch schedule. Simulation results show that the proposed strategy can compensate for the error in the day-ahead dispatch strategy based on short-time prediction (SP) of PWP. Thus, as an important supplement to the day-ahead dispatch strategy, this method is proved to be an effective solution to the power fluctuation problem in large-scale wind/photovoltaic integration, realizing a smooth power output, as well as guaranteeing the economical, efficient, and environmentally friendly operation of the system.

    ABSTRACT: Abstract—Self-excited induction generators are extensively used for wind power generation in remote and grid-isolated areas. It is challenging to maintain constant voltage and frequency under variable loads and variable wind speed conditions for such kinds of generators. This article proposes a hybrid reactive power control technique for induction generators through a fixed capacitor bank connected at the stator terminals and a strategically switched inverter source. The inverter's DC bus is connected to a photovoltaic panel and a storage battery. This scheme provides stable voltage output with changing loads and widely varying wind speeds. The capacitor provides the bulk excitation current for the induction generator, while the inverter provides the additional reactive current desired to regulate the generator output voltage under variable wind speeds and variable loads. Suitable simulations and experiments validate the proposed concept.
