Electrical Engineering HVDC Technology - Part 1

HVDC Technology – Part 1

Author: Velimir Lackovic

This course is the first part of a two part course on HVDC Technology. This course thoroughly presents HVDC concepts, available arrangements, operation and control issues. The first part of this course presents basic configurations, substation arrangements, converter operation and control. Electricity is produced as an alternating current (AC). It is also transferred and distributed as AC and in a majority of applications it is used as AC. Nevertheless, in many situations, it is financially and technically beneficial to use direct current (DC) links. In some situations, it may be the only possible power transmission method: if two different AC systems cannot be synchronized or when the interconnection cable length is too long for stable AC transmission, DC transmission can be applied. At the sending “converter station”, the AC is converted to DC current, which is then transferred to a second, receiving converter station where it is converted back to AC. In “back-to-back” HVDC arrangements the two converter stations are placed in the same building, reducing the DC transmission length to zero. HVDC transmission installations can be classified into four broad groups and any arrangement typically involves a combination of two or more of these. The groups are:

  • Transfer of bulk power where AC would be uneconomical or infeasible
  • Link between electrical systems which use different frequencies, or between non-synchronized or isolated power systems which, even though they have the same nominal frequency, cannot be run reliably in synchronism.
  • Introduction of power infeed without greatly increasing the short circuit level of the client’s AC system.
  • Improvement of AC system operation by the fast and precise control of HVDC power.

This course is suitable for electrical engineers with a desire to understand basic HVDC technology design and operation principles. It addresses HVDC configurations, HVDC substation design arrangements and equipment, converter operation and control.

Once you complete your course review, you need to take a multiple-choice quiz consisting of thirty (30) questions to earn 6 PDH credits
