4、 additions have been made to the informationpresented. The first release was to replace a 1954 AIEE Committee Report, Guide to Application andTreatment of Channels for Power-Line Carrier. This revision hopes to clarify areas where technology hasimproved as well as to add sections specifically concen

5、trated to protective relaying applications. Althoughthere are still uses in North America of the power-line carrier (PLC) for voice and supervisory applications,the predominate application is for dedicated protective relaying channels. To accomplish this task, thePower-Line Carrier Subcommittee of t

6、he Power Systems Communications Committee worked closely withthe Communications Subcommittee of the Power Systems Relaying Committee through parallel workinggroups in both committees. Details of the changes would be too numerous to note here. This guide is both a reference for theexperienced PLC eng

7、ineer as well as for the novice.PLC is not unique to only North America. Although it is not possible to describe differences in applicationsand philosophies, the principles presented here remain the same worldwide. This guide is dedicated to Mr. Herb Dobson, posthumously, as he was a noted expert in

ScopeThe purpose of this guide is to provide application information to users of carrier equipment as applied onpower transmission lin

27、es. Since the major applications of the power-line carrier (PLC) is for protectiverelaying, special consideration for these applications has been included. Information related to theexpanding usage of carriers on distribution lines below 69 kV is not specifically covered. Detailedequipment design in

28、formation is avoided as this is primarily the concern of equipment manufacturers.Material on PLC channel characteristics is presented along with discussions on intrabundle conductorsystems and insulated shield-wire systems. Procedures are provided for the calculation of channelperformance. Data for

29、the calculations are drawn from various sections of the guide. The couplingcomponents considered are line traps, coupling capacitors, line tuners, coaxial cables, hybrids, and filters.Frequency selection practices and future trends are discussed.An effort has been made to coordinate this guide with

PLC channelsA PLC channel includes the signal path from the transmitting electronic equipment at one terminal, thr

37、oughits coupling equipment, over the power line, through the tuning equipment at the receiving end, and into theelectronic equipment at the receiving terminal. In bidirectional applications, a similar return path isprovided.As shown in Figure 1, a basic PLC system consists of three distinct parts: t

38、he terminal assemblies, thecoupling equipment, and the transmission line. Terminal assemblies consist of transmitters, receivers, andprotective relays. The coupling equipment consists of the line tuner, coupling capacitor, and line trap. Thecoupling equipment provides a means of connecting the termi

39、nals to selected points on the powertransmission line. The transmission line provides a suitable path for the transmission of carrier energybetween terminals in the PLC band of frequencies. At the terminals, one or more transmitters and/orreceivers may be required, depending on the number of functio

40、ns to be performed.4IEC publications are available from the Sales Department of the International Electrotechnical Commission, Case Postale 131, 3, ruede Varemb, CH-1211, Genve 20, Switzerland/Suisse (http:/www.iec.ch/).

42、IDE FOR POWER-LINE CARRIER APPLICATIONS Std 643-2004Copyright 2005 IEEE. All rights reserved. 3Coupling of carrier energy to the transmission line is accomplished by the coupling capacitor, which is thephysical link to the transmission line that has a high impedance to the power frequency and a low

43、impedanceto carrier frequencies. The drain coil, which is part of the coupling capacitor (or additionally in the linetuner), provides a low impedance path to ground for power frequencies and a high impedance path forcarrier frequencies. The user should also be aware that if an optional drain coil is

44、 placed in the line tuner, theparallel combination of the two drain coils should be considered (refer to 7.3.4). The line tuner providesimpedance matching between terminal assemblies and the transmission line. It also provides for resonanttuning with the coupling capacitor. The line trap is inserted

45、 into power lines to minimize the loss of carrierenergy and to prevent external faults from shorting the carrier signal on the unfaulted line. The transmissionline provides the path for the PLC energy.PLC is a technique by which low radio-frequency (RF) currents are propagated over metallic conducto

46、rs,which may be either ac or dc overhead transmission lines or pipe type cable. The primary differencebetween high-voltage (HV) power transmission and PLC transmission is the frequency of operation.Although the fundamental principles of both transmissions are the same, many factors of primaryimporta

47、nce at PLC frequencies are negligible at power frequencies.Frequencies in the range of 30500 kHz have been employed for PLC. This frequency range is high enoughto be isolated from the power frequency energy and the noise it creates, but not so high as to encounterexcessive attenuation. Although freq

48、uencies somewhat lower than 30 kHz can be used, it is difficult toefficiently couple these frequencies to the transmission line by using coupling capacitors.Anytime voltage is discussed or V is used in an equation in this guide, it is always RMS voltage unlessotherwise specified.4. PLC applications4

49、.1 Relaying applications4.1.1 Interfacing PLC with relaysMany factors determine the form taken by the power-line carrierrelay interface, among which are the typeof protection scheme, the channel speed requirements, and the distance from the PLC equipment to therelays. This distance, if excessive, can affect both the output and the keying input conditions.Figure 1Diagram of a PLC channelIEEEStd 643-2004 IEEE GUIDE FOR POWER-LINE CARRIER APPLICATIONS4 Copyright 2005 IEEE.
