High Voltage Direct Current (HVDC) is now thetechnology of choice for subsea electricaltransmission, the interconnection ofasynchronous AC grids and long­distance bulkpower transmission. HVDC systems utilize powerelectronics technology to convert AC and DCvoltage, and are ideal for supporting existingsystems or building new power highways due toits efficient, stable transmission and controlcapability.

The GCCIA HVDC back– to – back convertersconsist of 3–poles of 660 MW each and link theasynchronous blocks of 50 and 60 Hz in theregion. One of the main functions of GCCIAHVDC is to constantly look for the occurrence ofa power generation or load loss in theinterconnected networks. When a disturbance isdetected, the HVDC link, through the use ofdynamic reserve power sharing functions, injectsor evacuate power and help restore the systemto normal conditions.

The training will provide technical informationabout the fundamentals and application of HVDCSchemes and will cover in detail the GCCIAHVDC Scheme and the Dynamic Reserve SharingFunctions including the functional specifications,system studies for the dynamic performance andthe synthesis of actual operation.

After this course participants will gain in­depthunderstanding of the various building blocks, types ofHVDC technologies, their typical applications and methods.The participants will understand how HVDC systems arespecified and designed and which developments can beexpected in the future.

The participants will acquire a deep understanding of HVDCtechnology and operating principles, including:

The main applications of HVDC; The operation of HVDC converters, both LCCs andVSCs; The control schemes of HVDC systems; Overview of GCCIA HVDC Scheme; Frequency Control (FC) & Dynamic Reserve PowerSharing (DRPS) functions of GCCIA HVDC Scheme

COURSE OBJECTIVE

INTENDED AUDIENCE

The course is designed for the Electrical Engineersassociated with the Operations of TransmissionNetworks, Economic Power Despatching andTransmission Network Planning in the GCC Region. Thetraining course will also suit the Operations andMaintenance Engineers of HVDC facilities and PowerSystem Researchers.
