    The lithium-ion vehicle battery market is forecast to grow to tens of thousands of megawatt hours and exceed $USD 30 billion annually in 2020. Retired batteries will typically retain 80% of their initial amp-hour capacity at the end of life and can either be recycled or disposed of in secondary markets. Given the volumes involved many markets may saturate and price will be determined by the econom... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1995 KB) | HTML iconHTML

    Large harmonic filter installations must perform over a broad set of impedance conditions that change according to operational contingencies at the point of common coupling, (PCC). A complex harmonic load, such as a railway feeder station, may be compactly characterized by a Thevenin or Norton network for each harmonic. Spread-sheet based tools can be developed to rapidly assess the harmonic impac... View full abstract»

  • Study on inrush current phenomenon in DC-DC converter with isolating transformer

    Publication Year: 2010, Page(s):1 - 6
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2598 KB) | HTML iconHTML

    This paper numerically studies the inrush current phenomenon in a DC-DC converter with isolating transformer. It uses Jiles-Atherthon method to model magnetic core used in isolating transformer. Due to fast change of switching duty-cycle to suit the load change, magnetic core experiences a large change of flux density, thereby inducing a large inrush current, though the operating point of the magn...

    Partial discharge (PD) plays a paramount role in determining system reliability. Exact detection and measurement of PD occurrence play a crucial role in high voltage (HV) apparatus operation and maintenance. To find better and cheaper ways to detect PD existence, many sensors have been developed. The high frequency current transformer (HFCT) sensors which are connected to the HV apparatus directly...

    In this paper, a novel method using Bees Algorithm (BA) is proposed to determine the Available Transfer Capability (ATC) of power transactions between source and sink areas in the deregulated power system. The objective of the algorithm is to maximize a specific point to point power transaction with system constraints violation through global optimal search. The security constraints that considere...

    Many of the power utilities around the world have experienced spurious tripping of directional earth fault relays in their mesh distribution networks due to induced circulating currents. This circulating current is zero sequence and induced in the healthy circuit due to the zero sequence current flow resulting from a ground fault of a parallel circuit. This paper quantitatively discusses the effec... View full abstract»

    Improving efficiency and flexibility in pulsed power supply technologies are the most substantial concerns of pulsed power systems specifically for plasma generation. Recently, the improvement of pulsed power supply becomes of greater concern due to extension of pulsed power applications to environmental and industrial areas. A current source based topology is proposed in this paper which gives th... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (231 KB) | HTML iconHTML

    The configuration proposed in this paper aims to generate high voltage for pulsed power applications. The main idea is to charge two groups of capacitors in parallel through an inductor and take the advantage of resonant phenomena in charging each capacitor up to a double input voltage level. In each resonant half a cycle, one of those capacitor groups are charged, and finally the charged capacito... View full abstract»

    To complement the traditional undergraduate lecture-based power electronics course material, the University of Canterbury has introduced a design and build assignment which focuses on motor control and the issues of interfacing to the mechanical world. Stimulation of the students' interest is achieved by using electric go-carts and holding a series of performance trials which pit teams of students... View full abstract»

    Distributors need to allocate a maximum allowed level of harmonic current to MV customers to keep voltage distortion acceptable. The paper describes a new approach, based on the concept of voltage droop, requiring much less calculation and data than required by the present approach based on an IEC technical report. The discrepancy between the new method and the present is studied by comparing some... View full abstract»

  • Design and development of a test rig to validate the concept of an Active Stirling Engine

    Publication Year: 2010, Page(s):1 - 6
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (821 KB) | HTML iconHTML

    In this paper, the design and development of a test rig to evaluate the performance of an Active Stirling Engine (ASE) is explained. Conventional Stirling engines have two moving elements; the piston and the displacer. Both the piston and displacer move sinusoidally, maintaining the same phase since they are mechanically connected to the same crank. In the ASE test rig, the displacer is disconnect...

    In this paper, both Distributed Generators (DG) and capacitors are allocated and sized optimally for improving line loss and reliability. The objective function is composed of the investment cost of DGs and capacitors along with loss and reliability which are converted to the genuine dollar. The bus voltage and line current are considered as constraints which should be satisfied during the optimiz... View full abstract»

    As more and more photovoltaic (PV) panels have been installed into power networks, PV systems need to be accurately modeled for power system analysis. The detailed model formed by power electronic devices is very inefficient in computation, so it is not suitable for large-scale and long period network level simulation. In the literature, photovoltaic system is simplified by a controlled current so... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (442 KB) | HTML iconHTML

    This paper discusses a hybrid control for the Static Var Compensator (SVC) to damp power fluctuations. In the proposed control, instantaneous power is calculated from the local measurement of three phase voltages and currents. A three phase voltage vector phase lock loop is used to get the phase angle information of the terminal voltages. The SVC reactive power injection is controlled in such a wa... View full abstract»

    Doubly fed induction generator (DFIG) is the most dominant technology used in wind energy conversion systems. Field-oriented vector control of DFIGs requires the knowledge of the instantaneous rotor position, which is usually obtained via high-resolution position sensors. However, using mechanical sensors increases the system cost and reduces the overall system reliability. This paper proposes a r... View full abstract»
