53 FOREWORD
54 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
55 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
56 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
57 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
58 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
59 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
60 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
61 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
62 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
63 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
64 consensus of opinion on the relevant subjects since each technical committee has representation from all
65 interested IEC National Committees.
66 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
67 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
68 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
69 misinterpretation by any end user.
70 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
71 transparently to the maximum extent possible in their national and regional publications. Any divergence between
72 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
73 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
74 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
75 services carried out by independent certification bodies.
76 6) All users should ensure that they have the latest edition of this publication.
77 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
78 members of its technical committees and IEC National Committees for any personal injury, property damage or
79 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
80 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
81 8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is
82 indispensable for the correct application of this publication.
83 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
84 rights. IEC shall not be held responsible for identifying any or all such patent rights.
85 IEC 63042-102 has been prepared by IEC technical committee TC122: UHV AC transmission
86 systems.

108 INTRODUCTION
109 Large-capacity power sources including large-scale renewable energy have recently been
110 developed, which are generally located far away from the load center. To meet the requirements
111 for large power transmission, some countries have introduced, or are considering introducing,
112 ultra high voltage (UHV) transmission systems, overlaying these on the existing transmission
113 systems at lower voltages such as 420 kV and 550 kV.
114 The objective of UHV AC power system planning/design is to achieve both economic efficiency
115 and high reliability, considering its impact on systems at lower voltages such as 420 kV and
116 550 kV.
117 Moreover, UHV AC transmission systems requires comparatively large space so that how to
118 realize to minimize and optimize the size and structure of UHV AC transmission lines and
119 substation apparatus is another important issue.

141 4 Objective and key issues of UHV AC transmission application
142 4.1 Objective
143 Recently, large-capacity power sources including large-scale renewable energy have been
144 developed, in most cases, far away from the load centres. To fully utilise these facilities, it is
145 important to transmit power generation from these sources efficiently. Evacuation through Extra
146 High Voltage (EHV) network enhancements would need more lines (Right-of-way, ROW) and
147 substation, increasing transmission losses and worsening fault current problems.
