High-Voltage Direct Current Transmission

2020
The HVDC transmission is advantageous for power delivery over long distances and asynchronous interconnections by using overhead lines or underground cables. One of the most important aspects of HVDC systems is its fast and stable controllability [6]. Until recently, the classic HVDC transmission based on thyristors was used for power conversion from ...

High Voltage Direct Current Transmission

2012
This chapter introduces the two main types of high-voltage direct-current (HVDC) transmission, i.e., the line-commutated current source converter (CSC) technology and its self-commutating voltage source converter (VSC) counterpart, and describes how both technologies can play a crucial role in the further development of power transmission systems.

Metrology for high voltage direct current

CPEM 2010, 2010
HVDC energy transmission is crucial for a successful uptake of renewable energy sources in the grid. A research program is described, intended to provide metrology support for the needs of HVDC energy transmission. This program will provide improvements for the present HVDC metrology infrastructure: accurate measurement of HVDC, determination of losses

A High Voltage Sensitivity Direct-Current Amplifier

Physics, 1933
It is shown that a negative resistance of a definite value, introduced into the plate circuit of a thermionic valve theoretically allows the voltage sensitivity to become infinite. Practical application is made to construct high sensitivity direct-current amplifiers. The data show a mutual conductance of 30,000 microamp. per volt.
