Reactive power compensation: a practical guide
Hofmann, Wolfgang
Schlabbach, Jürgen
Just, Wolfgang
The only practical guide to cover reactive power compensation in detail, presenting the design, application and operation of reactive power equipment and installations Written by experts in the field, this book is roughly (i.e. 20%) based on their successful German title Blindstrom-Kompensation in der Betriebspraxis (Reactive Compensation in Operational Practice). It first gives an overview of reactive power consumers and reactive power. The next chapters discussthe effects of reactive power on generation, transmission and distribution, and in reactive power energy contracts. Methods for determination of the reactive power and power factor are looked at, and then the improvement of power factor. The book then goes on to look at the design, arrangement and power of LV-capacitors and the determination of the required power of capacitors. The compensation of existing installations is covered in detail, as is the control andde-loading of reactive power. This unique book analyses the de-loading and the protection of capacitors and compensation, before covering the switching of capacitors in detail. There is a chapter devoted to installation, maintenance and disturbances, also a separate chapter on reactive power compensation of generation and unit special considerations. Finally, the book presents compensation and power converters. Presents a concise overview as well as deep specificknowledge on the Segment Power Factor Regulation and Network Quality The theory of reactive power compensation is coupled with typical application examplessuch as car manufacturing, metal rolling and chemical works Includes chapter summaries with charts explaining how to put the theory into practice Covers the economical aspects of this technology, including the efficient use of energyand the reduction of CO2 INDICE : 1 Introduction Transmission and Utilisation of electrical Energy Definition of reactive Power and Power Factor 2 Reactive Power Consumers and reactive Power Consumers in serial Connection Consumers in parallel Connection Mixed Connection Reactive Power of electrical Installations 3 Effects of reactive Power on Generation, Transmission and Distribution Currents of Generators and Lines Losses Generators Voltage drop Available Power of Transformers 4 Reactive Power in Energy Contracts Contractual Regulations of reactive Energy Contractual Regulations of reactive Power 5 Methods for Determination of reactivePower and Power Factor 6 Improvement of Power Factor Basics of reactive powercompensation Optimisation of reactive Power by selection of Motors and Load Profile Compensation by Generators Compensation by Capacitors 7 Design, Arrangement and Power of Capacitors Capacitors with Paper Dielectric Metal-paper Dielectric Synthetic-film Dielectric Arrangement and Power of Capacitors 8 Determination of required Power of Capacitors Basics of Calculation Calculation for new Installations 9 Types of reactive Power Compensation Single-type Compensation Bulk-type Compensation Central-type Compensation Mixed Compensation Advantages and Disadvantages 10 Compensation of existing Installations 11 Control of reactive Power Controlgear and Control-equipment Step number and related PowerC/k-value Reverse Control Scheme (cos j) Atomatic reactive Power Control Zero-voltage switching Reactive Power Control with mixed measuring Reactive Power Control with multiple infeed Measuring by Current Transformers Parallel Operation with multiple infeed 12 Discharging Devices for Capacitors Discharging Devices for LV-Capacitors Discharging Devices for MV-Capacitors 13 Protection of Capacitors Overcurrent and short-circuit Protetction Overvoltage Protection Protection against Temperature rise Unbalance Protection Protection against internal Faults 14 Switching of Capacitors Selection of Switchgear Switching by Semiconductors Thyristor Switching Reactive Power Control and Thyristor Control Dynamic reactive Power Control SVC 15 Installation, Maintenance and Disturbances 16 Reactive Power Compensation at Plants with Generators General 4-quadrantOperation Technical Considerations Bargaining Considerations 17 Effects Perturbations with Influence of Capacitors in Networks with Harmonics Network Perturbation and improved Network Quality Measuring and Analysis 18 Resonances in Power Systems Affects of Capacitors on the Network with Harmonics 19 Reactor protected Capacitors and Filter Circuits Effects of Reactor-protected Systems and System Configuration Reactive Reactors Design of Reactor-protected Systems Notes of Selection of Reactors Filter Circuits Design of Filter Circuits ActiveFilter Passive Filter Comparison of active and passive Filter Neutral Conductor Compensation 20Improvement of Power Quality Dynamic Compensation System 21 Compensation at Power Converters Compensation
