Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.

Real Time Digital Simulator or RTDS as the abbreviation recommended by IEEE committee on real-time simulator applied for power systems provides power systems simulation technology for fast, reliable, accurate, and cost-effective study of power systems [citation needed] with complex High Voltage Alternating Current (HVAC) and High Voltage Direct Current (HVDC) networks.
Electric power transmission through interconnectors using high-voltage direct-current (HVDC) involves usually two converter stations and a transmission line. Generally overhead lines are used, but an important class of HVDC projects use submarine power cables. A back-to-back station has no transmission line and joins two separate AC grids at a ...
The EMT-type software named EMTDC/PSCAD is currently developed and maintained by Manitoba HVDC Research Center. The real-time simulation tool named RTDS is commercialized by RTDS Technologies Inc. Hydro-Québec also developed a real-time EMT solver named Hypersim.
Although HVDC converters can, in principle, be constructed from diodes, such converters can only be used in rectification mode and the lack of controllability of the DC voltage is a serious disadvantage. Consequently, in practice all LCC HVDC systems use either grid-controlled mercury-arc valves (until the 1970s) or thyristors (to the present day).
Power engineering software is a software used to create models, analyze or calculate the design of Power stations, Overhead power lines, Transmission towers, Electrical grids, Grounding and Lightning [clarification needed] systems and others. It is a type of application software used for power engineering problems which are transformed into ...
A software bug was found to be the cause of the filter bank trips. 17 August 2021 – The HVDC transmission line failed in the Weka Pass region, leading to conductors of the Pole 2 circuit falling across State Highway 7. Transpower issued a Grid Emergency Notice later in the day, advising that there was insufficient generation and transmission ...
The Sichuan-Tibet Networking Project (Chinese: 川藏联网工程), or Sichuan-Tibet Interconnection Project, formally referred to as the Sichuan-Tibet Interconnection Transmission and Transformation Project, HVDC Sichuan-Tibet, seeks to link the power grid of Chamdo in Tibet with that of Sichuan, thereby terminating the prolonged isolation of the Chamdo region and fundamentally addressing the ...
