Design and Application of an Intelligent Monitoring System in HVDC Valve Hall
[Introduction] To overcome some shortcoming such as labor-intensity and inefficient-inspection in manual inspection, which is commonly adopted in the maintenance of the equipment in a HVDC valve hall, a intelligent monitoring system could be established.

Bipolar configuration is a new topology in the direct current (DC) system of photovoltaic power plants, which is topologically analogous to the bipolar configuration utilised in High‐Voltage Direct Current power transmission systems. DC cable length and copper usage are reduced by 50% using a bipolar configuration.

PMU‐Based Wide Area Monitoring With Machine Learning to Prevent Blackouts in Bangladesh Power System
A Unified Real‐time Dynamic State Measurements (URTDSM) system with PMU and Phasor Data Concentrator (PDC) deployment plan has been proposed to avoid blackout in the Bangladeshi power system. Machine learning has been used to process data from PMU to identify abnormal events. ABSTRACT The electrical power system must be trustworthy and secure enough to

Abstract Geomagnetic observatory networks provide continuous data for space weather monitoring, field modeling, and solid Earth geophysics. Rapid urbanization, however, has introduced pervasive electromagnetic interference from subway traction systems, degrading data quality at a growing number of urban stations.

Hybrid Filters To Damp Harmonic Resonance In Power Transmission Systems
Problems related to harmonic propagation in transmission systems have been noticed in the last years. Passive filters, commonly used to attenuate noncharacteristic harmonics in HVDC systems, stay at risk of disconnection from the system due to ...

Type Tests for Hybrid HVDC Breakers: a Technical Feasible Solution
In the coming years, the use of the HVDC circuit breakers will become a necessity in the “grids of the future” (basically multi-terminal HVDC grids). An obliged step is to test such equipment before to install it on the grids.

MMC Stored Energy Participation to the DC Bus Voltage Control in an HVDC Link [PDF]
The modular multilevel converter (MMC) is becoming a promising converter technology for HVDC transmission systems. Contrary to the conventional two- or three-level VSC-HVDC links, no capacitors are connected directly on the dc bus in an MMC-HVDC link ...
