hvdc
This dc/dc converter is connected in series with a pole of the HVDC transmission line.
      
This HVDC tap can supply high quality ac power to isolated areas, with or without ac power generation.
      
The controller of the HVDC tap is independent from the master control of the HVDC link.
      
It does not need any communication channel to the control of the main HVDC converter stations.
      
Simulation results have revealed that the proposed HVDC tap can be a very good option for feeding small loads along the HVDC transmission line.
      
the load loss measurement of HVDC power transformers according to the draft of IEC standard 61378-2 [1] - a load loss measurement at frequencies other than rated frequency is required.
      
Multipulse converters and controls for HVDC and FACTS systems
      
Robust controls for HVDC and FACTS systems based on multipulse converters were developed.
      
The developed HVDC system makes the rectifier station to control the instantaneous active (real) power through the HVDC voltage link, whereas the inverter station controls the instantaneous reactive (imaginary) power generation.
      
A complete model of a 100?MW, 33?kVac, 50/60?Hz, 24-pulse HVDC system was implemented in the electromagnetic transient program (EMTP/ATP).
      
The conventional method of calculating high-voltage direct current (HVDC) converter commutation angles can result in very inaccurate results if the ripple of the DC is fairly high, or the HVDC link consists of capacitor commutated converters (CCC).
      
The method is demonstrated and the advantages are indicated by means of an example network consisting of a HVDC system.
      
A New Damper Scheme to Restrict Torsional Torques on the Turbine Generator Shafts and Blades near a HVDC Link
      
Due to more various power disturbances occurring in a power system involving a HVDC link, the turbine generator shafts and/or blades are more prone to damage than in general HVAC systems.
      
The results demonstrate that the best damper may not be installed at the location with the most onerous vibrations but provides satisfactory damping performance on shafts and blades following severe power disturbances in a HVDC link.
      
Simulation of the insulation properties of a HVDC transformer using a hybrid discretization based on finite elements and harmoni
      
The deleterious effects resulting from the electrolysis of HV porcelain are discussed with particular regard to the insulation requirements of HVDC mercury valves.
      
XLP cable is poorly suited to HVDC because charge and impurity migration leads to very high local gradients on polarity reversal.
      
APS is the power distribution system that supplies power to the components in an HVDC plant.
      
ABB introduced 1997 a different HVDC technology from the present standards.
