Opis: Power Supply Devices and Systems of Relay Protection - Vladimir Gurevich

Power Supply Devices and Systems of Relay Protection brings relay protection and electrical power engineers a single, concentrated source of information on auxiliary power supply systems and devices. The book also tackles specific problems and solutions of relay protection power supply systems and devices, which are often not dealt with in the literature. The author, an experienced engineer with more than 100 patents, draws on his own experience to offer practical, tested advice to readers. A Guide to Relay Protection Power Supply for Engineers and Technicians The first chapter reviews the electronics and primary elements of the system, including transistors, thyristors, optocouplers, logic elements, and relays, and their principles of operation. This background gives staff who service relay protection power supply systems the necessary electronics knowledge to help them work more effectively with the equipment. The next chapters of the book then cover built-in digital protection relay power supplies, battery chargers, accumulator batteries, uninterruptible power supply, and characteristic features of auxiliary DC systems at substations and power plants. The final chapters discuss questions and problems that engineers and technicians may face. These include insulation problems, issues in auxiliary DC power supply such as voltage dips, and electromagnetic disturbances such as blackouts, spikes, and surges. The author also explains how to address them. Suitable for beginners and experienced engineers alike, the book is written for those who work with relay protection systems and with AC and DC auxiliary power systems in power plants and substations. It combines theory and practical recommendations to provide a valuable reference on power supply devices and systems.Basic Components Semiconducting Materials and p-n Junctions The Transistor's Principle Some Types of Transistors Bipolar Transistor General Modes Transistor Devices in Switching Mode Thyristors Optocouplers Electromagnetic Relays References Secondary Power Supplies Introduction Comparative Characteristics of Linear and Switch-Mode Power Supplies Problems with Electrolytic Capacitors Conclusions and Recommendations References Battery Chargers Purpose and Modes of Operation of Battery Chargers Arrangement and Principle of Operation of a Classical BC on Thyristors BCs with a Function of Discharging the Battery BCs with Two Rates of Output Voltage Principle of Action of BC with a High-Frequency Link Ferroresonant-Type BCs Autoreclosing of a BC A Problem of High Capacitance on BC Output Ports Arrangement of Alarm about Failure of Transformers in Control Unit of BC Problems of Electromagnetic Relays in BCs A Device to Monitor Proper Ventilator Functionality in Sites with Batteries References Uninterruptable Power Supply Diversity of Uninterruptable Power Supplies Static Switch Inverter Group Powering of UPS A Problem of Energy Quality in Networks with UPS High-Voltage UPS Aggregate Additional Problems of the UPS Dynamic and Hybrid UPSs References LeadAcid Accumulator Batteries Background Principle of Lead-Acid Accumulator Operation Effect of Electrode Sulfation on Accumulator Performance Classification of Lead-Acid Accumulators Types of Lead-Acid Accumulator Battery Plates Types of Electrolytes Dry-Charged Accumulator Batteries The Capacity of an Accumulator Battery Selection of an Accumulator Battery References Systems for Supervision of Substation Battery Continuity Introduction Existing System for Supervision of Substation Battery Continuity Suggested Method for Supervision of Substation Battery Continuity Device for Supervision of Battery Circuit Based on Nonlinear Shunt Using a Standard Shunt as Current Sensor Using the Hall-Effect Sensor in Systems for Supervision of Battery Circuits Newest Developments and Prospects of Their Application Conclusion References Backup of Substation DC Auxiliary Power Systems Characteristics of Backup Layout with Diodes DPR Protection Device Automatic Reclosing Device for DCAPS References Insulation Problems in Substation DC Auxiliary Power Supply Faulty Actuation of Relay Protection at Grounding of One of the Poles of Auxiliary DC Power Supply Insulation Problems in Substation DCAPS References Voltage Disturbances in Auxiliary Power Supply Electromagnetic Disturbances in the Power Network Voltage Sags in AC Networks Problematic Action of the Powerful Contactors as Changeover from Main to Reserved Auxiliary AC Power Supply on Substations Problems in Auxiliary DC Power Supply Voltage Dips in Auxiliary Power Supply Substation Systems References Index
