Research on Relay Protection Schema and Protection Setting of Large Capacity Synchronous Condenser

Research on the Relay Protection System of Micro-grid

Original scientific paper In this paper, the necessity of the protective relay of the micro-grid is described as the anti-islanding protection and Low Voltage Ride Through (LVRT), and the fault characteristics of the renewable energy sources are analysed. The applicability of over-current protection, distance protection, differential protection, pilot protection, voltage protection and frequenc...

Loss-of-Field Protection Relay Coordination for Synchronous Generator and Motor Unit Based on Transient Stability

Digital Communications for Relay Protection

Electric utilities are expanding communications infrastructure due to increased need for information. Due to performance, price, and technological advances, digital communication systems are frequently chosen as this multiple user data network. This two-part paper describes the application of digital communication in power system protection. Part 1 describes the digital communications architect...

Effect of Protection and Preventive Behavioral Training Package from Covid-19 on Self-Protection Motivation

Introduction: The Covid-19 pandemic and its effects on health and social life have made proper training necessary for protective and preventive behaviors. This study aimed to determine the effectiveness of protective and preventive behavior training on students' self-protection motivation during the outbreak of Covid-19. Methods: The method of the present study was a semi-experimental pre-test/...

Application of SVC on Large Synchronous Motors Based on LOC Design (RESEARCH NOTE)

This paper describes the application of static var compensators, (SVC) on an electrical distribution network containing two large synchronous motors, one of which is excited via a three-phase thyristor bridge rectifier. The second machine is excited via a diode bridge rectifier. Based on linear optimization control (LOC), the measurable feedback signals are applied to the control system loops o...
