This arrangement is fitted with a control system designed to control the active and reactive power towards their specific set point values, while balancing the voltages of the two dc link capacitors in real time. Obtained results show the effectiveness of the proposed HVDC transmission system. 展开...
To investigate how the presence of HVAC transmission lines changes the ion-flow field, experiments are carried out on an indoor test model with bipolar dc and three-phase ac lines. The experiment results are then compared with the simulation results. The experiment and simulation results show ...
The results of several tests of these special control functions carried out during commissioning are presented as well as a brief discussion on equipment related problems and initial operating experience. The 440 MW Leyte-Luzon HVDC Transmission Project connects the power system of Luzon, the major ...
Electric power transmission systems come as high voltage alternating current (HVAC), extra or ultra high voltage AC (EHVAC or UHVAC), high phase order (HPO) HVAC, 50, 60 and fractional frequency transmission systems, high voltage direct current (HVDC), monopole HVDC, bipole HVDC, tripole ...
The eigenvalues were used to analyze the influence of system parameters on SSO damping. Research results showed that there was an SSO mode in which D-PMSG and LCC-HVDC participated together, and the LCC-HVDC connection provided negative damping for the system SSO. When the D-PMSG transmission ...
This paper study the power system restoration procedure with external power supplies through HVDC transmission channel. The simplified models of the transmission system under different control modes are established and their stability margin are analyzed by root locus diagram. In consideration of the influ...
