Three-Phase Induction Motor
Three-Phase Induction Motor EXPERIMENT Induction motor Three-Phase Induction Motors 208VLL OBJECTIVE This experiment demonstrates the performance of squirrel-cage induction motors and the method for deriving electrical equivalent circuits from test data.

BACKGROUND INFORMATION The three-phase squirrel-cage induction motor can, and many times does, have the same armature (stator) winding as the three-phase synchronous motor. As in the synchronous motor, applying three-phase currents to the armature creates a synchronously-rotating magnetic field. The induction motor rotor is a completely short-circuited conductive cage. Figures 1 and 2 illustrate the rotor construction. Revised: April 11, 2013 1 of 10 Three-Phase Induction Motor Figure 1: Induction machine construction. Figure 2: Squirrel-case rotor. Revised: April 11, 2013 2 of 10 Three-Phase Induction Motor The rotor receives its excitation by induction from the armature field. Hence, the induction machine is a doubly-excited machine in the same sense as the synchronous and DC machines. The basic principle of operation is described by Faraday’s Law. If we assume that the machine rotor is at a standstill and the armature is excited, then the armature-produced rotating field is moving with respect to the rotor. In fact, the relative speed between the rotating field and the rotor is synchronous speed. -
Distribution Transformers
Shoemaker_CH15.qxd 13/07/06 11:43AM Page 15.1 CHAPTER 15 DISTRIBUTION TRANSFORMERS The purpose of a distribution transformer is to reduce the primary voltage of the electric distribution system to the utilization voltage serving the customer. A distribution trans- former is a static device constructed with two or more windings used to transfer alternating- current electric power by electromagnetic induction from one circuit to another at the same frequency but with different values of voltage and current. Figure 15.1 shows distribution transformers in stock at an electric utility company ser- vice building. The distribution transformers available for use for various applications, as shown, include pole-type (Figs. 15.2 and 15.3), pad-mounted (Fig. 15.4), vault or network type (Fig. 15.5), and submersible (Fig. 15.6). The distribution transformer in Fig. 15.2 is self-protected. It is equipped with a lightning arrester, a weak-link or protective-link expulsion-type fuse (installed under oil in the trans- former tank), a secondary circuit breaker, and a warning light. The transformer primary bushing conductor is connected to one phase of the three-phase primary circuit through a partial-range current-limiting fuse. The transformer tank is grounded and connected to the FIGURE 15.1 Electric utility distribution storage yard. Forklift trucks are used to load transformers on line trucks.

Coupling for Power Line Communication: a Survey Luis Guilherme Da S
JOURNAL OF COMMUNICATION AND INFORMATION SYSTEMS, VOL. 32, NO. 1, 2017. 8 Coupling for Power Line Communication: A Survey Luis Guilherme da S. Costa, Antonio Carlos M. de Queiroz, Bamidele Adebisi, Vinicius L. R. da Costa, and Moises V. Ribeiro Abstract—The advent of power line communication (PLC) electric power cables. These power cables could be alternating for smart grids, vehicular communications, internet of things current (AC) or direct current (DC) power lines and the signals and data network access has recently gained ample interest in of PLC transceivers are subsequently coupled to them via a industry and academia. Due to the characteristics of electric power grids and regulatory constraints, the effectiveness of coupling circuit. In the case of power lines used to transmit coupling between the power line and PLC transceivers has AC power, the coupling circuit has also to filter out the AC become a very important issue. Coupling devices used to inject or mains signal. On the other hand, the coupling circuit simply extract data communication signals into or from power lines are has to block the DC mains voltage of the DC electric power very important components of a PLC system. There is, however, grids. an obvious gap in the literature for a detailed review of existing PLC couplers. In this paper, we present a comprehensive review During the late 1970s and early 1980s, new investigations of couplers, which are required for narrowband and broadband to characterize electric power grids as a medium for data PLC transceivers. Prevailing issues that protract the design of communication showed a higher potential in the range of couplers and consequently subtended the inventions of different frequencies between 5 kHz and 500 kHz [2]. -

182 Chapter 7 Analysis and Simulation of Ipm Generator
182 CHAPTER 7 ANALYSIS AND SIMULATION OF IPM GENERATOR DRIVING AN INDUCTION MACHINE 7.1 Introduction In this chapter, the analysis and simulation results of the IPM generator driving a three phases, one horsepower induction machine will be presented. A schematic of the topology can be seen in Figure 7.1. Shunt capacitors placed at the terminals of the IPM are used to boost the terminal voltage and to supply reactive power. For the two machines used in the experiment, the use of the capacitors was not optional because it was found that the induction machine would not even start without the presence of the capacitors. In the first part of the chapter, the dynamic and steady state equations used to model the induction machine will be presented. Next, the value of the parameters of the induction machine (and the methods used to determine the parameters) will be given. The comparison between the steady state experiment and calculated results will then be compared. Finally, simulated waveforms will be presented which show how the system behaves for three different types of load. 183 7.2 Derivation of Dynamic and Steady State Equations of a Squirrel Cage Induction Machine The d q stator (after the stator resistance and core loss (see Figure 7.2)) and rotor voltage equations of the induction machine for the voltage can be written as V qss = ω λ ds + p λ qs V dss = - ω λ qs + p λ ds (7.1) V qr = rr I qr + (ω - ωr )λ dr + p λ qr V dr = rr I dr - (ω - ωr )λ qr + p λ dr , where λ qs = Llsm I qsm + Lmm ( I qsm + I qr ) λ ds = Llsm I dsm + Lmm ( I dsm + I dr ) (7.2) λ qr = Llr I qr + Lmm ( I qsm + I qr ) λ dr = Llr I dr + Lmm ( I dsm + I dr ) .
