    16、cal Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this e

    17、nd and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organi

    18、zations lialsing with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on tech

    19、nical matters, express as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published i

    20、n the form of standards, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national

    21、 and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conf

    22、ormity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to pr

    23、epare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical report of one of the following types: type 1, when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts; type 2,

    24、 when the subject is still under technical development or where for any other reason there is the future but not immediate possibility of an agreement on an International Standard; type 3, when a technical committee has collected data of a different kind from that which is normally published as an I

    25、nternational Standard, for example “state of the art”. Technical reports of types1 and2 are subject to review within three years of publication to decide whether they can be transformed into International Standards. Technical reports of type3 do not necessarily have to be reviewed until the data the

    26、y provide are considered to be no longer valid or useful. IEC1334-1-1, which is a technical report of type3, has been prepared by IEC technical committee57: Power system control and associated communications. The text of this technical report is based on the following documents: Full information on

    27、the voting for the approval of this standard can be found in the report on voting indicated in the above table. This series of IEC1334, listed in Annex B, concerns distribution automation systems supported by two-way communication channels using medium-and low-voltage distribution power mains as dat

    28、a transmission media. Such communication channels will be referred to as “DLC”, which stands for distribution line carrier. Distribution automation systems are intended to provide a large amount of facilities related to two main applications, concerning network automation and customer service automa

    29、tion. Committee draft Report on voting 57 (SEC) 196 57/240/RVCBSIEC 61334-1-1:1995 iv BSI 03-1999 Table 1 summarizes the most important options concerning the above-mentioned applications. Requirements concerning these options will be included in the future IEC1334-1-2. As medium-voltage and low-vol

    30、tage power mains have been designed for electric energy supply, and, consequently, can only offer poor performances for data transmission, stringent requirements are necessary in order to ensure data integrity and transmission efficiency suitable to the application needs. The aim of these publicatio

    31、ns is to provide adequate information for correct design and reliable operation of distribution automation systems using DLC.BSIEC 61334-1-1:1995 BSI 03-1999 1 Introduction Distribution networks, in spite of being difficult channels for data communication because of signal attenuation, noise level a

    32、nd the fact that coupling side impedance can vary unpredictably with time, have always been considered by the electric utilities as the most attractive resource for supporting the introduction of automation techniques aimed at reducing operating cost and capital expenditure. Compared to other commun

    33、ication media, distribution networks are owned by the electric utilities. This allows the creation of new services without requiring additional communication carrier costs or significant operational increase of costs. Moreover, electric utilities can keep direct control over the transmission equipme

    34、nt, thus avoiding reliance on a third party. For these reasons, a number of communication systems using distribution networks as a transmission medium have been already developed at industrial levels. The first systems, due to the limited possibilities offered by technology, could only offer a one-w

    35、ay link from control centres towards the remote equipment to be controlled. However, they opened the way to the implementation of distribution automation techniques suitable to satisfactorily respond to certain important needs, mainly related to the field of customer service automation, as for examp

    36、le: introduction of advanced tariff system (indirect load management); direct management of customer load. In more recent years, due to the progress of electronics, two-way communication systems providing low data transmission speed (not more than a few bits/s) have been installed. They have been ut

    37、ilized to support network automation techniques requiring the acknowledgement of commands sent towards line switches, as for example: automatic sectionalizing of feeders affected by fault; remote operation of capacitor banks. At present industrial development of very effective two-way communication

    38、systems can be envisaged. Their main feature is the ability to provide higher data transmission speed (from tens to hundreds of bits/s), so that a single channel can support most applications of distribution automation, thus allowing favourable cost/benefits evaluation. In this way, a large number o

    39、f facilities related to both network and customer service automation seems to be able to find a very comprehensive solution within the framework of integrated distribution automation systems. It should be noticed that, even though the technique for transmitting communication signals on a distributio

    40、n network is quite similar to that already well developed for high-voltage lines, stringent constraint for identifying cost-effective solutions is to be considered as a mandatory requirement. Experience with high-voltage line carrier systems may not be directly applicable to distribution network lin

    41、e-carrier systems due to factors including cost considerations. Therefore, line carrier communication systems on distribution networks should be treated as a completely new application area in relation to what is already known four high-voltage networks. 1 Scope This technical report of type 3, afte

    42、r a short description of the structure of distribution networks for both medium-and low-voltage levels, presents the architecture of a distribution automation system (DAS) using distribution line carrier systems. It outlines and discusses the interaction between the distribution network structure an

    43、d the configuration of the distribution automation system. It provides an overview of the functional elements which constitute the basic structure and it deals with the main options concerning the coupling methods for the transmission signal injection. It also identifies the ISO-OSI levels involved

    44、in the functional architecture of distribution automation systems. 2 Reference documents IEC 38:1983, IEC standard voltages.

    45、udes two main power networks referred to as MV (medium-voltage) and LV (low-voltage). Table 2 summarizes the values of standard and exceptional voltages of the distribution power network, according to IEC38.BSIEC 61334-1-1:1995 2 BSI 03-1999 3.1 MV power network MV power networks are supplied throug

    46、h HV/MV transformers, installed in HV/MV substations, typically as shown in Figure 1. Each HV/MV transformer whose MV winding neutral point can be either isolated or connected to earth by means of a suitable impedance supplies a section of busbar. Each busbar section supplies a number of MV feeders

    47、through circuit-breakers with associated protection and possibly control (auto-reclosing) devioes. MV busbar sections in an HV/MV substation may be interconnected through a circuit-breaker to allow energizing all the MV feeders from one HV/MV transformer. For power factor compensation, one switched

    48、capacitor bank per busbar section may also be installed. MV feeders are an aggregation of several line sections delimited by switches, without any protection device associated, installed within an MV/LV substation. A typical diagram is shown in Figure 2. In relation to the operation of line switches

    49、, which can be either motorized or not, the resulting configuration of the MV power network is dynamic. Each line section can be composed of one or more of the following main types: underground or overhead insulated cables, overhead lines with bare conductors. Since most feeders rejoin MV busbar of adjacent HV/MV substations, the MV power network composed by MV feeders and MV/LV substations is a meshed network. A typical diagram is shown in Figure 3. In some cases, the MV network supplied by the same HV/MV substations, can in
