Foreword This document is an adaptation of the IEC Standard 61800-4 with the addition of requirements pertinent to use of these devices in the U.S. U.S.

37、differences are indicated with (U.S. Differences) and italics. 1) The IEC (International Electrotechnical 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-op

38、eration on all questions concerning standardization in the electrical and electronic fields. To this end 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

39、with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determine

40、d by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical 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

41、. 3) The documents produced have the form of recommendations for international use and are published in the form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC N

42、ational Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national 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 pr

43、ovides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity 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. The

44、 IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61800-4 was prepared by IEC sub-committee 22G: Semiconductor power converters for adjustable speed electric drive systems, of IEC technical committee 22: Power electronic systems and equipmen

45、t. Annexes A, B and C are for information only. The committee has decided that the contents of this publication will remain unchanged until 2008. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. ICS 61800-4-2004 Page vi Copyright 2004 by the Na

Section 1 GENERAL 1.1 SCOPE AND OBJECT It applies to power drive systems (see figure 1) with converter voltages (line-to-line voltage), between 1 kV a.c. and 35 k

47、V a.c., input side 50 Hz or 60 Hz, and load side frequencies up to 600 Hz. Requirements for voltages above 15 kV are not included and are defined by agreement between the manufacturer and the system supplier. For power drive systems, with voltages above 1 kV, using a step-down input transformer and/

48、or a step-up output transformer in connection with a low voltage converter (below 1 000 V), IEC 61800-2 applies. EMC aspects are covered in IEC 61800-3. U.S. NOTE: EMC Immunity and Emission requirements of IEC 61800-3 are not applicable within the U.S. Specific safety requirements for drive systems

49、with voltage above 1 kV will be covered in IEC 61800-5. This standard gives the characteristics of the converters, their topologies and their relationship with the complete a.c. drive system. It also states their performance requirements with respect to ratings, normal operating conditions, overload conditions, surge withstand capabilities, stability, protection, a.c. line earthing, topologies and testing. Furthermore, it deals with application guidelines, such as control strategies, torsion analysis, recommendations for earthing and drive system component integr
