An HVDC converter station (or simply converter station) is a specialised type of substation which forms the terminal equipment for a high-voltage direct current (HVDC) transmission line. [1] It converts direct current to alternating current or the reverse.

Most HVDC links use voltages between 100 kV and 800 kV. HVDC lines are commonly used for long-distance power transmission, since they require fewer conductors and incur less power loss than equivalent AC lines. HVDC also allows power transmission between AC transmission systems that are not synchronized.

This article explores the latest developments and applications of HVDC substations, providing a technical explanation of HVDC technology, recent innovations in HVDC converter stations, integration with renewable energy sources, and examples of major T&D utility HVDC projects contributing to grid modernization.

of Insulated Gate Bipolar Transistors (IGBT) with high voltage ratings have accelerated the development of voltage sourced converters for HVDC applications in the lower power range. The main characteristics of the voltage sourced converters are a compact design, four-quadrant operation capability and high losses.

2013年1月25日 · High voltage substations are interconnection points within the power transmission and distribution systems between regions and countries. Different applications of substations lead to HV substations with and without power transformers:

2022年3月7日 · Two main high voltage direct current (HVDC) technologies: line-commutated converters (LCC), also known as current-source converters (CSC) using thyristors, and voltage-source converters (VSC)-HVDC, using IGBT transistors, both …

High Voltage Direct Current Transmission. The purpose of this section is to provide an introduction to the two fundamental modes in which electric energy is transmitted—alternating current (AC) and direct current (DC)—and to compare the ability of these two options to address the challenges of enhancing the resiliency of modern power grid.

Siemens Energy high-voltage substations with air-insulated switchgear (AIS) are the cost-efficient choice for rated voltages of up to 800 kV. They are renowned for highest reliability, economical operation, and low maintenance requirements.

High-voltage direct current (HVDC) transmission systems are becoming more and more important in the global energy landscape which is characterized by increased digitalization, accelerated decarbonization and the unprecedented uptake of distributed energy resources (DER), inverter based resources (IBR) and distributed power generation in general.

2012年2月24日 · The massive transmission of electricity in the form of DC over long distances by means of submarine cables or overhead transmission line is the high voltage direct current transmission. This type of transmission is preferred over HVAC transmission for very long distance when considering the cost, losses and many other…
