Here, the relationship between DC component and spectral components of corona current on HVDC transmission lines in the band of 2-20 kHz was analysed. First, a lot of corona current data were measured in two HVDC experiment bases. Then, the expression representing the correlation between DC ...
We discuss a number of practical implications from recent studies on HVDC design concepts for vacuum components. These studies dealt with microwave tube technology. The conclusions, however, are valid for a wide range of components. The goal of this work is to provide a scientific basis for the...

Here, the judgment of transient voltage stability employs a heuristic energy function method. Finally, simulation tests on three-machine system with a HVDC transmission line are conducted in PSAT package, and the obtained results demonstrate the feasibility and effectiveness of the proposed method....
Model Integration and Control Interaction Analysis of AC/VSC HVDC System The development of voltage source converter (VSC) based high voltage direct current (HVDC) transmission has progressed rapidly worldwide over the past few years. The UK transmission system is going through a radical change in ...
the first patent dataset entirely dedicated to offshore wind energy is built, covering key technology components (such as, foundations, towers, power transmission, blades, rotors, and submarine cables), as well as hybrid systems to combine offshore wind energy with other sources of energy, and ...
The main components of converting substations are rectifiers (to converter ac into dc) and inverters (to converter dc into ac). These substations are generally located at the sending and receiving ends of the HVDC power lines. Indoor Substations ...
