Novel leakage current sensor for non-intrusive dielectric state assessment of HVDC cables
This paper proposes a monitoring principle based on leakage current measurements to monitor the state and health of HVDC cable dielectric.
Circuit based implementation of the Universal Line Model in Matlab/Simulink
This paper presents an improved version of the Universal Line Model (ULM) also known as Wide-Band (WB) model.
Impact of cable modeling in electromagnetic transient simulations of MVDC systems
This paper explores how choice of the cable system model may impact the simulated electromagnetic transient response of a MVDC system under fault situations.
DC time constant evaluation for HVDC gas insulated system cable connection assemblies
DC time constants in different parts are computed and presented in this paper for a cable GIS fluid filled connection assembly.
Thesis defence replay: “Condition and Health Monitoring of Modular Multilevel Converter for HVDC Grids”
This work on Modular Multilevel Converter is particularly interesting for converter manufacturers who want to optimise the maintenance of their equipment.
Direct current circuit breaker with adjustable current injection
New DC interrupting principle adjusts the injected counter current to use the vacuum bottle’s interruption capability under optimum conditions.
Fault ride through of dc solid state transformer in MVDC systems
This article introduces the MVDC network fault ride-through (FRT) requirement and the response of a DC solid state transformer is analyzed.
PhD Diego VELAZCO: “Condition and Health Monitoring of Modular Multilevel Converter for HVDC Grids”
This thesis addresses the condition monitoring and the prognosis of the remaining useful life of IGBT modules in a HVDC-MMC application.
From pole-to-ground fault current return paths in a meshed HVDC network to a grounding modelling simplification for protection studies
This article deals with fault currents return paths in case of pole-to-ground fault in a grounding configuration using surge arresters in all stations except one, which is solidly grounded.
