Abstract

This paper describes the control design of the Santo tome' back-to-back HVDC link. The Santo Tome' HVDC converter will be the second dc link asynchronously connecting the Argentina and Brazil power systems. This paper focuses on the design of the reactive power control, automatic power control, load frequency control, power modulation control, automatic frequency control, and automatic synchronizing control functions of the 50 MW dc link. Time simulation and frequency domain results are included to illustrate the system response and verify the adequacy of the controllers performance in achieving stable operating conditions.

Analysis of variable-frequency currents superimposed on DC currents in asynchronous HVDC Links in stressing turbine-generator-exciter shafts

Journal Article Hammons, T; Bremner, J - IEEE Transactions on Energy Conversion

Ripple currents on the DC side of both HVDC asynchronous and synchronous Links can excite in some circumstances onerous torsional vibrations in large steam generator shafts. The problem has assumed importance in recent months on account of the HVDC Link between Scotland and Northern Ireland going ahead, on account of the proposed Eire/Wales Link, because AC/DC/AC couplers are to be installed to interconnect the East and West European Grid Systems, and because resonances have been observed on machines in close proximity to AC/DCIAC couplers and HVDC Links.

Improving the dynamic performance of a complex AC/DC system by HVDC control modifications

Journal Article Hammad, A; Gagnon, J; McCallum, D - IEEE Power Engineering Review (Institute of Electrical and Electronics Engineers); (United States)

The power system of Hydro-Quebec has a peak load of approximately 27 GW. The great distance between the production sites and the load centers introduces stability limitations, which is the reason why the Quebec grid cannot be economically synchronized (through ac transmission with limited capacity) with the U.S. northeastern network. Power exports are therefore dependent on the use of HVDC links of which Hydro-Quebec now possesses five, for a capacity of over 2600 MW. Such a capacity will again soon increase. At the moment, the Chateauguay scheme has the largest HVDC capacity. It transfers 1000 MW by means of twomore »« less

Stressing of turbine-generator-exciter shafts by variable-frequency currents superimposed on DC currents in asynchronous HVDC links and following disturbances at converter stations

Journal Article Hammons, T; Bremner, J - IEEE Transactions on Energy Conversion (Institute of Electrical and Electronics Engineers); (United States)

Ripple currents on the DC side of both HVDC synchronous and asynchronous. Links together with cleared HVDC and AC system disturbances can excite in some circumstances onerous torsional vibrations in large steam generator shafts. The problem has assumed importance in recent months on account of the HVDC Link between Scotland and Northern Ireland going ahead, on account of the proposed Eire/Wales Link, and because AC/DC/AC couplers are to be installed extensively to interconnect the East and West European Grid Systems.

Power links with Ireland -- Excitation of turbine-generator shaft torsional vibrations by variable frequency currents superimposed on DC currents in asynchronous HVDC links

Journal Article Hammons, T; Tay, B; Kok, K - IEEE Transactions on Power Systems

The paper describes an in-depth analysis of excitation of shaft torsional vibrations in steam-turbine-generator-exciter shafts in close proximity to HVDC converter stations by variable-frequency ripple currents superimposed on the DC currents in asynchronous Links. It extends earlier work to include an in depth analysis of system scaling factors for harmonic currents impressed on generators in Northern Ireland by an inverter and to investigate the phenomena for possible torsional vibrations in the generators by the Link. Frequencies at which shaft torsional vibrations would be excited by modulation product harmonics in 50Hz/50Hz asynchronous Links as a function of deviation in system frequencymore »« less

Unified active and reactive power modulation of HVDC systems: large-signal and distributed small-signal control. Final report

Technical Report Grund, C

Advanced HVDC modulation control techniques have been developed and evaluated for the stabilization of torque-angle oscillations of ac/dc networks. Previous work resulted in centralized small-signal modulation control (EPRI Reports EL-2101 and EL-3990). This report covers extensions to decentralized small-signal and large-signal modulation to augment power system steady-state and transient stability, respectively. Decentralized modulation requires a frequency controller at each terminal of a two-terminal dc system. Each modulation signal (dc power and voltage) is produced at the terminal where it is required and therefore it does not have to be transmitted between terminals. Dynamic performance is comparable to a centralized modulationmore »« less
