Transmitting power at high voltage and in DC form instead of AC is a new technology proven to be economic and simple in operation which is HVDC transmission. The HVDC (High Voltage Direct Current) technology is used to transmit electricity over long distances by overhead transmission lines or submarine cables. It is also used to interconnect separate power systems. A further development in this...

During the last three decades, reliability analysis of power systems considering transformers, breakers, transmission lines, and generators failure has been widely applied. This analysis has been done especially in the generation and transmission levels and is mainly restricted to high voltage alternating current (HVAC) systems. HVDC transmission systems are becoming increasingly popular when c...

Summary: We developed a controller that is compliant with the Chado database schema, GBrowse and genome annotation-editing tools such as Artemis and Apollo. It enables the management of public and private data, monitors manual annotation (with controlled vocabularies, structural and functional annotation controls) and stores versions of annotation for all modified features. The Chado controller...

When we research the suppression problem of subsynchronous oscillation based on time domain simulation method, we find the appropriate parameters for phase compensation and amplitude gaining links are important to the damping effect of the additional damping controllers, supplementary excitation damping controller(SEDC) and subsynchronous supplementary damping controller(SSDC). Some scholars at...

In meshed high-voltage direct current (HVdc) grid, the flows through lines cannot be controlled with sufficient freedom without additional power electronics-based devices, namely flow controller (CFC). this article, a novel hybrid modular interline CFC is proposed based on H-bridge submodules and thyristor valves. Due to its modularity, particularly suitable for applications requiring high volt...
