MTDC and DC Systems | Control, Protection, and Study
There are several methods of control in MTDC systems. Only parallel MTDC systems are considered as these involve complexities in extending the existing control methods. The various methods suggested are…
MTDC | Introduction, Potential Applications, and Types
Introduction HVDC transmission systems designed and operated so far are point-to-point systems with two terminals (converter stations). A multiterminal DC (MTDC) system has more than two converter stations, some operating…
DC Breakers | Characteristics, Types, and Applications
Introduction The development of HVDC circuit breakers has been underway for some time in the late eighties, and a 500 kV breaker with current interrupting capability up to 4000A, has…
DC Generator | Construction and Working Principle
DC Generator A DC generator is an electrical machine whose main function is to convert mechanical energy into electricity. When the conductor slashes magnetic flux, an emf will be generated…
Characteristics and Advantages of A.C. Over D.C. and Vice Versa
In a closed circuit, an electric current is the flow of electrons. There are two kinds of electric currents Direct current (D.C) and Alternating current (A.C) 1. Direct Current: In…
AC and DC System : What is AC and DC Transmission System
What is AC System The ac system is mainly used for transmission of power supply. The ac transmission line transmits alternating current over a long distance. The universally adopted AC…
