E-Book Overview

English translation of well known soviet book (/file/15605/ ; /file/33765/). 1977. — 430 p.This is the third Russian edition of "Automation in Electrical Power Systems" which covers design and operation of automatic control devices intended to prevent and clear faults in electrical power systems and restore power to the loads in the event of breakdown thus assuring continuity of the supply.The reliable and unfailing operation of such devices has been ensured through the research and development effort put into automatic power control systems.The book discusses automatic control in conjunction with protective relaying, since the required reliability and economy of power system operation can be achieved through the combined action of both groups of equipment, each catering for specific aspects in functioning of loads and generating sources.The wide use of automatic control systems adds to the reliability, stability and economy of power supply systems and takes some burden from attending personnel.The book is designed as a study guide for students of power engineering secondary schools. It may also interest engineers concerned with the operation, installation and design of protective relaying and automatic devices used in electric power stations and networks.<strong>Contents:preface.<strong>Introductionpurpose of Automatic power Control Systems.Elements of Automatic Control Systems.Automatic Control and Controllers.Relays and Relaying Devices.Elements of Logic Operations.Connection Diagrams.Conclusions.Review Questions.<strong>Automatic Control of Synchronous Generator Excitationpurpose of Automatic Excitation Control (Alc) Devices.Automatic Excitation Forcing of a Generator.Excitation Compounding with Cumulative Connection of Electromagnetic Voltage Corrector.Excitation Controllers of Generators, Series Tw, with a High-Frequency.Excitation System.Overaction Excitation Controllers.Conclusions.Review Questions.<strong>Automatic Voltage RegulationGeneral.Use of Aec devices.Group Control of Generator Excitation.Automatic Devices for Changing the Transformation Ratio of power Transformers.Devices for Automatic Capacity Control of Capacitor Banks.Voltage Regulation by Booster Transformers.Voltage Regulation by Changing Excitation of Synchronous Capacitor.Voltage Regulation by Controlled Reactors.Conclusions.Review Questions.<strong>Excitation Systems and Automatic Field Discharge Devices of Synchronous MachinesGeneral.Exciters Using Gas-Discharge Tubes and Thyristors.Brushless Excitation System.Excitation Systems of Large Turbogenerators.Field Discharge by Deion Grid Automatic Devices and by Changing the Field Coil Supply to Inverter Operation.Conclusions.Review Questions.<strong>Automatic Controls for Maintaining Stability in parallel Operation and Elimination of Asynchronous OperationGeneral.principal Relations Determining Operation of Automatic Controls.Automatic Controls for Improvement of Steady-State Stability.Automatic Controls for Improvement of Transient Stability.Automatic Devices for Sectionalizing power Systems to prevent or Eliminate.Asynchronous Operation.Separation of Small Thermal power Stations from Large Hydroelectric Stations when Speed of Hydroelectric Generators Increases.preventing Misoperation of protective Relaying.Conclusions.Review Questions.<strong>Automatic Frequency Controlpurpose and Specific Fea
