  • Local Area Conventional Protection

    Higher demand is putting stress on the reliability, rapidity and sensitivity of local area conventional protection. This chapter introduces an improved scheme for transformer differential protection and new protection schemes different from differential protection. In the chapter, voltage and current information are comprehensively utilized and a few new transformer protection schemes are constructed based on equivalent instantaneous leakage inductance and generalized instantaneous power. These schemes can efficiently solve the problems of lack of sensitivity when no‐load switching at faults and malfunction in the case of TA saturation due to external fault. With regard to transformer protection, the demand for high reliability and rapid response are on the increase, with larger capacity transformers constantly being brought into operation. The chapter further introduces a new location method for multiple inter‐line and grounded faults of double‐circuit transmission lines based on compensation voltage.

  • Finite‐Element Solution of Magnetic Circuits

    This chapter presents the basic method of first‐order triangular finite elements to illustrate its use in both two‐dimensional linear and nonlinear magnetostatic problems. For a two‐dimensional magnetostatic problem, the magnetic vector potential concept is a useful approach which reduces the number of unknown functions. To the finite‐element discretization scheme, the variational approach is discussed in the chapter. The variational method consists of constructing a set of approximate functions which minimize the energy stored in the system. It is possible to show that the approximating function is the required solution to the differential equation which satisfies the given boundary conditions. The first‐order finite‐element solution technique described in the chapter assumes that the field excitation is a consequence of source currents in the region. Another possible source of excitation is that of permanent magnets. The chapter further shows the second quadrant of the B‐H characteristic of a permanent magnet.

  • The MMF and Field Distribution of an AC Winding

    This chapter introduces the "forcing function" of the magnetic field of a typical AC machine, namely the stator magnetomotive force (MMF). The stator MMF primarily acts to magnetize the machine and is accounted for, in the per phase equivalent circuit, by the magnetizing inductance. The chapter explores MMF distributions for two‐pole, single‐circuit machines, and discusses the actual number of electrical poles, however, depends on design considerations. This number is nearly always greater than two since two‐pole machines are particularly wasteful of stator conductors due to large return paths at the end of the machine (end windings). The chapter shows a schematic representation of a single‐phase full pitch winding, and fractional pitch winding. Windings are generally distributed in several slots in order to better utilize the available space around the periphery of the machine. In most cases, winding distributions are nearly always symmetrical if the number of slots per pole per phase is two or greater.

  • Electromagnetic Design of Synchronous Machines

    This chapter considers the design of salient pole synchronous machines. Synchronous machines are nearly always designed so that the magnetic circuit, particularly the rotor poles, is rather highly saturated. Hence, in order to obtain useful values for machine parameters, a simple superposition scheme based on computing the fluxes produced first by the field and then by the stator MMF independently and adding the result is usually inapplicable. A solution must be obtained with the machine at a representative operating condition, usually as close to rated load and power factor as can be estimated. The analysis of a synchronous machine begins by calculating the magnetizing inductance associated with the direct axis component of stator current. The direct axis magnetizing inductance is equal to the flux linkages produced by the stator currents divided by the _d_‐axis component of stator current.

  • Fundamental Field Equations

    The fundamental field equations for electromagnetic fields are Maxwell's equations. This chapter reviews differential and integral forms of these equations and discusses boundary conditions, energy relations, Poynting's theorem, the uniqueness theorem, and the reciprocity theorem. Vector and scalar potentials and Hertz vectors are discussed, as they give alternative and often simpler formulations of the problem. Although electromagnetic waves are vector fields, they can sometimes be represented or approximated by scalar fields. The chapter presents formulations for scalar acoustic waves as examples of scalar fields. The wave at a single frequency is often called a time‐harmonic or monochromatic wave and is most conveniently described by the real part of the phasor field. The chapter considers Maxwell's equations for time‐harmonic electromagnetic fields and the general time‐varying electromagnetic fields satisfying Maxwell's equations. The complete mathematical description of the electromagnetic problem includes Maxwell's equations, boundary conditions, the radiation condition, and the edge condition.

It includes revisions on chapters devoted to the physical principles of RFID systems and microprocessors, and supplies up-to-date details on relevant standards and regulations. The text explores schematic circuits of simple transponders and readers, and includes new material on active and passive transponders, ISO/IEC 18000 family, ISO/IEC 15691 and 15692. It also describes the technical limits of RFID systems. A unique resource offering a complete overview of the large and varied world of RFID, Klaus Finkenzeller's volume is useful for end-users of the technology as well as practitioners in auto ID and IT designers of RFI products. Computer and electronics engineers in security system development, microchip designers, and materials handling specialists benefit from this book, as do automation, industrial and transport engineers. Clear and thorough explanations also make this an excellent introduction to the topic for graduate level students in electronics and industrial engineering design.

  • Miscellaneous MCSA Case Histories

    This chapter presents a diverse range of Motor Current Signature Analysis (MCSA) industrial case histories obtained during routine MCSA surveys, which were carried out to assess the condition of cage windings in squirrel cage induction motors (SCIMs). During routine MCSA surveys to ascertain whether ¿¿2sf sidebands exist in the current spectrum from cage winding breaks, it was observed in a case history that abnormal current components existed in the current spectrum from one of the Seawater Lift Pump (SWLP) motors. One of the case histories shows that a mechanical problem such as worn belts and/or slipping belts can be diagnosed via MCSA but comparisons between spectra from identical drive trains are required and also subsequent trending of the spectra, thus this approach is not truly diagnostic as is the case with detecting ¿¿2sf sidebands due to broken rotor bars.

  • Magnetic Mirror Model

    Improved magnetic mirror models (IM3) for mono and dual coils with a finite width and infinite permeability are explained in this chapter [47]. By introducing a mirror current, which is located at the same distance from a source current but with a smaller magnitude than the source current, the magnetic flux density of the mono and dual coils can be determined in a closed form. The ratio of the mirror current and source current is identified as a function of the width of the core plate and the distance between the source current and core plate, as rigorously derived from the finite¿¿¿element method (FEM) simulations. Applying the proposed IM3 to the mono and dual coils used for wireless electric vehicles, the magnetic flux density over an open core plate is analyzed and its maximum points on the plate are found, which is crucial in the design of the coils to avoid local magnetic saturation. Furthermore, the magnetic flux density when a pick¿¿¿up core plate is positioned over a primary core plate is also analyzed by introducing successive mirror currents. The proposed magnetic mirror models are extensively verified by experiments as well as site tests, showing quite promising practical usefulness.This chapter is based on the paper by W.Y. Lee, J. Huh, S.Y. Choi, X.V. Thai, J.H. Kim, E.A. Al¿¿¿Ammar, M.A. El¿¿¿Kady, and C.T. Rim, ¿¿¿Finite¿¿¿width magnetic mirror models of mono and dual coils for wireless electric vehicles,¿¿¿ _IEEE Trans. on Power Electronics_, vol. 28, no. 3, pp. 1413¿¿¿1428, March 2013.

  • Asymmetric Coils for Large Tolerance EV Chargers

    As discussed in the previous chapter, large tolerance is one of the best characteristics of a static electric vehicle (EV) charger, but only if no severe penalty for the larger tolerance is found. In this chapter, an explanation is given of asymmetric coil sets for wireless stationary EV chargers, which have a significantly larger lateral tolerance than any others in the world.The pick¿¿¿up coil set is much smaller than the power supply coil set, thereby allowing large lateral and longitudinal displacements as well as robustness to airgap displacement. EMF is reasonably reduced by arranging magnetic poles along the EV's moving direction so that alternating magnetic flux through adjacent poles cancel each other. A dominant field analysis (DoFA) useful for complex vector magnetic flux simulation is used, which was introduced in Chapter 15 and is applicable to any resonating coils of inductive power transfer systems (IPTSs). Furthermore, a hysteresis loss model is suggested, which appropriately reflects the partial core saturation in a system analysis.A prototype IPTS including the proposed coil sets were designed and successfully verified by experiments. In the quick charging mode, maximum output power of 15 kW, large lateral displacement of 40 cm, longitudinal displacement of 20 cm, and an airgap of 15 cm were achieved, and low EMF of 6.1 ¿¿T at 20 kHz was achieved in the normal charging mode of 5 kW.This chapter is written based on the paper by S.Y. Choi, B.W. Gu, J. Huh, W.Y. Lee, J.G. Cho, and C.T. Rim, ¿¿¿Asymmetric coil sets for wireless stationary EV chargers with large lateral tolerance by dominant field analysis,¿¿¿ _IEEE Trans. on Power Electronics_, vol. 29, no. 12, pp. 6406¿¿¿6420, December 2014.

  • Narrow¿¿¿Width Single¿¿¿Phase Power Rail (I¿¿¿type)

    In this chapter, an advanced version of on¿¿¿line electric vehicles (OLEVs) is introduced as an introductory example of road¿¿¿powered electric vehicles (RPEVs). Because the author is heavily involved in the development of OLEVs, this chapter will guide readers to how practical problems are dealt with. This chapter is based on the paper by J. Huh, S.W. Lee, W.Y. Lee, G.H. Cho, and C.T. Rim, ¿¿¿Narrow¿¿¿width inductive power transfer system for on¿¿¿line electrical vehicles,¿¿¿ _IEEE Trans. on Power Electronics_, vol. 26, no. 12, pp. 3666¿¿¿3679, December 2011.The inductive power transfer system (IPTS) with a narrow rail width, a small pick¿¿¿up size, and a large airgap is explained, as an extension of previous research on OLEVs, in this chapter. By introducing a new core structure, the orientation of the magnetic flux alternates along with the road; hence, an inductive power transfer system with a narrow rail width of 10 cm, a large airgap of 20 cm, and a large lateral displacement of about 24 cm was implemented. The resonant circuit of the inductive power transfer system, driven by a current source, was fully characterized. The experimental results showed that the maximum output power was 35 kW and that the maximum efficiency was 74% at 27 kW.
