Descriptive material intended to assist in the planning for design, development, and operation of small hydroelectric power plant control systems is presented. The controlled electrical and mechanical systems and equipment as well as the control systems are covered. The aim, which is basically tutorial, is to provide a working knowledge of the terminology used in this field and an understanding of the principles of operation of hydroelectric generating units. The control requirements are addressed from an electrical standpoint. For completeness, salient civil features of small hydroelectric projects, are mentioned and equipment protection and operation are discussed.
Working Group Details
IEEE Guide for Control of Hydroelectric Power Plants
Superseded by IEEE Std 1010-2006 Abstract: The control and monitoring requirements for equipment and systems associated with conventional and pumped-storage hydroelectric plants are described. Typical methods of local and remote control, details of the control interfaces for plant equipment, requirements for centralized and off-site control, and trends in control systems are included. The various categories that affect the levels of control for a plant, namely, location, mode, and supervision, are described. Block diagrams and descriptions of the control and monitoring requirements for major plant systems and equipment are given. Control sequencing of generating and pumped storage units, centralized control, and off-site control are covered. The information is directed toward practicing engineers in the field of power plant design who have a basic knowledge of hydroelectric facilities.
IEEE Guide for Installation of Vertical Generators and Generator/Motors for Hydroelectric Applications
This standard describes installation procedures for synchronous generators and generator/motors rated 5000 kVA and above, to be coupled to hydraulic turbines having vertical shafts.
IEEE Guide for the Application of Turbine Governing Systems for Hydroelectric Generating Units
This guide is intended to complement IEEE Std 125-1988TM, providing application details and addressing the impact of plant and system features upon hydroelectric unit governing performance. It provides guidance for the design and application of hydroelectric turbine governing systems. There is a heightened awareness within the electric utility industry of the importance in the effective application of governing systems for dynamic stability. The need exists to provide guidance in the effective governing system application for a better understanding among users.
IEEE Guide for Computer-Based Control for Hydroelectric Power Plant Automation
The application, design concepts, and implementation of computer-based control systems for hydroelectric power plant automation is addressed. Functional capabilities, performance requirements, interface requirements, hardware considerations, and operator training are discussed. Recommendations for system testing and acceptance are provided, and case studies of actual computer-based control applications are presented.
IEEE Recommended Practice for Preparation of Equipment Specifications for Speed-Governing of Hydraulic Turbines Intended to Drive Electric Generators
This recommended practice is intended to assist users with the preparation of procurement specifications for electric-hydraulic speed governors. Remarks: Superseded by IEEE Std 125-2007
IEEE Standard for Hydraulic Turbine and Generator Integrally Forged Shaft Couplings and Shaft Runout Tolerances
This recommended practice provides a single source of implementation instructions that, when used with related recommended practices concerning unique identification principles and definitions, component function identifiers, and system descriptions, provide a basis for uniquely identifying systems, structures, and components of nuclear and fossil-fueled power plant projects (electric power generating stations) and related facilities. Hydro and other types of power plants are not included. The standard is part of a series of recommended practices, entitled the Energy Industry Identification Systems (EIIS), the purpose of which is to present a common language of communication which will permit a user to correlate a system, structure, or component with that of another organization for the purposes of reporting, comparison, or general communication. A significant feature of this concept is that the unique identification code identifies the function at the component level and not the hardware itself.
