DC Filters | Criteria, Carrier Frequency, and RI Noise
DC Filters | Criteria, Carrier Frequency, and RI Noise

Criteria of Design The harmonics in the DC voltage across the converter contain characteristic and non-characteristic orders. These harmonics result in current harmonics in DC lines and cause noise in…

Harmonics | Introduction, Generation, and Non - Characteristics
Harmonics | Introduction, Generation, and Non – Characteristics

Introduction HVDC converters introduce both AC and DC harmonics which are injected into the AC system and DC line respectively. There are several problems associated with the injection of harmonics…

Reactive Power Control | Requirement, Sources, and Transients
Reactive Power Control | Requirement, Sources, and Transients

Introduction The converters in conventional HVDC power stations are line-commutated, which implies that the current initiation in the valve can only be delayed concerning the zero crossing of the converter…

Smoothing Reactor and DC Line | Transient overvoltages, Protection, and Effects
Smoothing Reactor and DC Line | Transient overvoltages, Protection, and Effects

Introduction The smoothing reactor is connected before the DC filter and in series with the converters. Apart from smoothing the direct current, it also serves as a buffer between the…

DC Breakers | Characteristics, Types, and Applications
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…

Static Relays I Basis, Classification, and Components

Introduction A static protective relay refers to a relay in which the measurement or comparison of electrical quantities is done in a static network which is designed to give an…

Static Relay | Components, Working, Types, and Applications
Static Relay | Components, Working, Types, and Applications

Introduction The solid-state relay, also known as a static relay, was introduced back in 1960. Unlike traditional relays, it doesn't have any moving parts. This makes it more durable and…
