FOREWORD
1) ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)
form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards through technical committees established by the
respective organization to deal with particular fields of technical activity. ISO and IEC technical committees
collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental,
in liaison with ISO and IEC, also take part in the work.
2) The formal decisions or agreements of IEC and ISO 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 IEC and ISO National bodies.
3) IEC and ISO documents have the form of recommendations for international use and are accepted by IEC and
ISO National bodies in that sense. While all reasonable efforts are made to ensure that the technical content of
IEC and ISO documents is accurate, IEC and ISO cannot be held responsible for the way in which they are used
or for any misinterpretation by any end user.
4) In order to promote international uniformity, IEC and ISO National bodies undertake to apply IEC and ISO
documents transparently to the maximum extent possible in their national and regional publications. Any
divergence between any IEC and ISO document and the corresponding national or regional publication shall be
clearly indicated in the latter.
5) IEC and ISO do not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC and ISO marks of conformity. IEC and ISO are not
responsible for any services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this document.
7) No liability shall attach to IEC and ISO or their directors, employees, servants or agents including individual
experts and members of its technical committees and IEC and ISO National bodies for any personal injury,
property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including
legal fees) and expenses arising out of the publication, use of, or reliance upon, this ISO/IEC document or any
other IEC and ISO documents.
8) Attention is drawn to the Normative references cited in this document. Use of the referenced publications is
indispensable for the correct application of this document.
9) Attention is drawn to the possibility that some of the elements of this ISO/IEC document may be the subject of
patent rights. IEC and ISO shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
The data collected from various types of electrical equipment is sparsely located, and on-line
transmission of the data helps to collaboratively aggregate and analyse them in real-time.
Transitioning to the smart electrical power substation using wireless communication among the
sensor nodes – i.e. wireless sensor network (WSN) – requires systems architecture provisioning
automated data collection from the electrical equipment, which allows collaborative data
processing, sends automatic alerts, provides preventive actions, and potentially takes
corrective actions for certain situations.
Electrical power substation communications should be designed to support scalability,
interoperability, autonomous fault correction, and other key attributes. The intelligent wireless
sensor network (iWSN) is inherently flexible and scalable in its capabilities and in operations
including in the size of its converge areas; however, depending on the geographical (e.g. urban,
suburban, remote location) and structural (both natural and man-made) situations, the
installation architecture should ensure the fidelity of all sensor nodes’ wireless connectivity.
Furthermore, the WSNs can support either distributed or decentralized network architecture.
The wired substation network typically uses high-availability seamless ring (HSR) and parallel
redundancy protocol (PRP) protocols (see IEC 62439-3, IEC 61850-8-1 and IEC 61850-9-2) to
provide seamless failover against failure of any network component. For the iWSN, it is also
important to have the key iWSN network components (e.g. sensor nodes) from data
communication failure. Therefore it is important to select wireless sensor network architecture
for a substation which overcomes the potential issue of a single point of failure in the wireless
sensor network, for example, by installation architecture, the use of PRP to improve packet loss
and timing behaviour in wireless network, or a combination of these.
This document introduces iWSN as a system which helps to make the power substation sma
