WG 14 - TC 4/WG 14

IEC/IEEE 63198-2775:2023 describes the integrated control and management of smart hydroelectric power plants and groups of plants using the latest proven and widely accepted digital equipment. The descriptions are applicable to all types of hydroelectric power plants except tidal and ocean power plants.
Based on internationally standardized communication models, this document incorporates guidelines for communication networks, sensors, local monitoring and control equipment, Integrated Control and Management Platform (ICAMP) as well as intelligent applications. In addition, special attention is also given to cyber security.
This document considers the future structure of completely digitalized power plants equipped with digitalized sensors and actuators as well as the intelligent control and management of power plants with existing instrumentation.

IEC 62270:2013 addresses the application, design concepts, and implementation of computer-based control systems for hydroelectric plant automation. It addresses functional capabilities, performance requirements, interface requirements, hardware considerations, and operator training. It includes recommendations for system testing and acceptance. The electrical protective system (generator and step-up transformer) is beyond the scope of this guide. This second edition cancels and replaces the first edition published in 2004. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- update of system architecture aspects, with different process control system configurations;
- update of communications, user and plant interfaces aspects;
- suppression of case studies, because of the quickness of evolution of the technology;
- complete review of the bibliography, making mention of many IEC and IEEE standards as new references and addition of a new informative Annex B on legacy control systems. This publication is published as an IEC/IEEE Dual Logo standard. Key words: Hydroelectric, Automation, Computer-Based Control

IEC 61362:2012 includes relevant technical data necessary to describe hydraulic turbine governing systems and to define their performance. It is aimed at unifying and thus facilitating the selection of relevant parameters in bidding specifications and technical bids. It will also serve as a basis for setting up technical guarantees. The scope of this standard is restricted to the turbine governing level. Additionally some remarks about the control loops of the plant level and about primary and secondary frequency control (see also Annex B) are made for better understanding without making a claim to be complete. Important topics covered are:
- speed, power, water level, opening and flow (discharge) control for reaction and impulse-type turbines including double regulated machines;
- means of providing actuating energy;
- safety devices for emergency shutdown.
To facilitate the setting up of specifications, this guide also includes data sheets, which are to be filled out by the customer and the supplier in the various stages of the project and the contract. Acceptance tests, specific test procedures and guarantees are outside the scope of the guide; those topics are covered by IEC 60308. This second edition cancels and replaces the first edition published in 1998. It is a technical revision. It takes into account the experience with the guide during the last decade as well as the progress in the state of the art of the underlying technologies. Keywords: Hydraulic turbine, Hydraulic turbine governing systems.

IEC 60308:2005 deals with the definition and the characteristics of control systems. It is not limited to the actual controller tasks but also includes other tasks which may be assigned to a control system, such as sequence control tasks, safety and provision for the actuating energy. The following systems are included, speed, power, opening, water level and flow control for all turbine types; electronic, electrical and fluid power devices; safety devices as well as start-up and shutdown devices.
