TECHNICAL GUIDELINES FOR SMART HYDROELECTRIC POWER PLANT

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC document(s)"). 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 organizations liaising
with the IEC also participate in this preparation.
IEEE Standards documents are developed within IEEE Societies and Standards Coordinating Committees of the
IEEE Standards Association (IEEE SA) Standards Board. IEEE develops its standards through a consensus
development process, approved by the American National Standards Institute, which brings together volunteers
representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members
of IEEE and serve without compensation. While IEEE administers the process and establishes rules to promote
fairness in the consensus development process, IEEE does not independently evaluate, test, or verify the
accuracy of any of the information contained in its standards. Use of IEEE Standards documents is wholly
voluntary. IEEE documents are made available for use subject to important notices and legal disclaimers (see
https://standards.ieee.org/ipr/disclaimers.html for more information).
IEC collaborates closely with IEEE in accordance with conditions determined by agreement between the two
organizations. This Dual Logo International Standard was jointly developed by the IEC and IEEE under the terms
of that agreement.
2) The formal decisions of 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 IEC
National Committees. The formal decisions of IEEE on technical matters, once consensus within IEEE Societies
and Standards Coordinating Committees has been reached, is determined by a balanced ballot of materially
interested parties who indicate interest in reviewing the proposed standard. Final approval of the IEEE standards
document is given by the IEEE Standards Association (IEEE SA) Standards Board.
3) IEC/IEEE Publications have the form of recommendations for international use and are accepted by IEC National
Committees/IEEE Societies in that sense. While all reasonable efforts are made to ensure that the technical
content of IEC/IEEE Publications is accurate, IEC or IEEE 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 National Committees undertake to apply IEC Publications
(including IEC/IEEE Publications) transparently to the maximum extent possible in their national and regional
publications. Any divergence between any IEC/IEEE Publication and the corresponding national or regional
publication shall be clearly indicated in the latter.
5) IEC and IEEE do not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC and IEEE 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 publication.
7) No liability shall attach to IEC or IEEE or their directors, employees, servants or agents including individual
experts and members of technical committees and IEC National Committees, or volunteers of IEEE Societies and
the Standards Coordinating Committees of the IEEE Standards Association (IEEE SA) Standards Board, 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 IEC/IEEE
Publication or any other IEC or IEEE Publications.
8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that implementation of this IEC/IEEE Publication may require use of material
covered by patent rights. By publication of this standard, no position is taken with respect to the existence or
validity of any patent rights in connection therewith. IEC or IEEE shall not be held responsible for identifying
Essential Patent Claims for which a license may be required, for conducting inquiries into the legal validity or
scope of Patent Claims or determining whether any licensing terms or conditions provided in connection with
submission of a Letter of Assurance, if any, or in any licensing agreements are reasonable or non-discriminatory.
Users of this standard are expressly advised that determination of the validity of any patent rights, and the risk
of infringement of such rights, is entirely their own responsibility.

INTRODUCTION
In the past few decades, the widespread use of automatic control systems in hydroelectric
power plants, including computer-based control systems, brought a number of benefits including
improved work efficiency, enhanced reliability and real-time capability, as well as optimized
Operating Expense (OPEX).
Nowadays, tremendous changes occur in hydroelectric power plants and their external
environment, thereby posing challenges in operation, maintenance, scheduling and
management.
The evolution of power grid codes and electricity markets, the growing sensibility of the public
about the environmental impact and such risks generated by operating hydroelectric power
plants as control of flow variation downstream, and the increasing demand for multi-purpose
utilization of water resources lead to the increasing difficulty in generation scheduling decision-
making. Giant unit/plant capacity enhances the role of hydroelectric power plants in maintaining
grid stability. The rationale for developing cascade hydroelectric power plants has been widely
recognized, as integrated operation and maintenance requirements have become increasingly
prominent. The latest technologies such as cloud computing, Artificial Intelligence (AI), big data,
Internet of Things (IoT), mobile terminal, and Virtual Reality (VR) are triggering a revolution in
hydroelectric power plant automation systems.
Newly installed, renovated and partially refurbished hydroelectric power plants and remote
control centers need innovative technologies to strengthen information sharing and coordination
among equipment and applications. With the goal to realize multi-dimensional information
sensing, comprehensive data display, interactive applications and intelligent warnings and
decisions, and to cope with the challenges of operation, maintenance, dispatching and
management, innovation involving multiple elements regarding system architecture, information
model, integrated standards, software structures, business procedure, applications, optimized
models, etc., should be conducted. The innovation based on such elements is multi-dimensional,
flexible and open to different demands, rather than a mere improvement of certain technologies,
so that hydroelectric power plants and remote control centers where those innovations are put
into use can be called a smart hydroelectric power plant.
In the present document, open architecture has been proposed for a smart hydroelectric power
plant and technical requirements for each part have been specified, thus improving the safe,
reliable, efficient and economic operation of hydroelectric power plants/remote control centers,
enhancing the interaction with the smart grid and facilitating ecological and environmental
responsibility. The overall system structure and functionality are mainly determined by the
scales, types, importance and complexity of specific smart hydroelectric power plants. The
document describes a representative set of architectures, components and functionalities. The
appropriate selection, extension or modification tailored to the needs of a specific power plant
shall be chosen in a specific project. The document can be used as a reference for engineers
of hydroelectric power plants/remote control centers, consultants or automation system vendors
in helping the design of smart hydroelectric power plants, development of hardware and
software products, implementation of projects, and compilation of related documents.
