Yip H.T., Lloyd G. Operation and Design of a Protection Relay for Transformer Condition Monitoring. Часть 1

Since 1966, the Network Protection and Automation Guide (formerly the Protective Relays Application Guide) has been the definitive reference textbook for protection engineers and technicians. For 2011, Alstom has capitalised on its pool of experts at the St Leonards Centre of Excellence in Stafford UK to launch a new edition. 1 Introduction 2 Fundamentals of Protection Practice 3 Fundamental Theory Новейшая редакция учебникa по релейной защи...

1977. , 430 pages. English translation of well known soviet book ( ; . Preface 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 e...

Oleg Bagleybter Sankara Subramanian 14стр In order to test the protection with different CT remanence values every fault is applied six times: three times with a positiveDC component and three times with a negativeDC component.

Differential protection is a fast, selective method of protection against short-circuits which is applied in many variants for electrical machines, transformers, busbars, and electric lines. Initially this book covers the fundamentals of analog and digital differential protection. The emphasis is then placed on the different variants of differential protection and its practical application, which is illustrated by concrete examples. A textbook a...

Dr. Alexander ApostolovSt. Petersburg, Russia, 2011 25стр Introduction IEC 61850 standard has a significant impact on the development of a new generation protection solutions The paper analyzes conventional centralized and distributed bus differential protection schemes and compares them with IEC 61850 station and process bus based solutions.

H.T. Yip, M. Moscoso, G. Lloyd, K. Liu, Z. Wang –ALSTOM Grid 21стр Traditional bias characteristic: Improves stability during CT saturation. Considers 2nd harmonic blocking or restraining to provide stability during inrush. Traditional bias characteristic limitations: Dual slope characteristic on its own may not maintain stability without requiring excessive over-dimensioning of the CTs. 2nd harmonic technique may slow down the bias different...

V.G. Kurbatsky, D.N. Sidorov, V.A Spiryaev, N.V. Tomin Energy Systems Institute SB RAS Russia 18стр Introduction Improvement of the efficiency of systems of emergency and secure control of electrical power systems (EPS) is largely dependent on the wide-scale monitoring and forecasting the parameters of the expected operation regime of the EPS, first of all on the frequency of the electrical network and the active power flows. A powerful instrume...
