Course details

This course introduces High Voltage DC (HVDC) Transmission in a clear and simple way, focusing on why and how HVDC is used in modern power systems. It begins with the evolution of power systems, explaining the limitations of AC transmission over long distances and how HVDC emerged as a solution. The course then compares AC and DC transmission, highlighting efficiency, controllability, and stability aspects. You will learn about the basic principles of HVDC, including power conversion and control. Different types of HVDC systems such as monopolar, bipolar, and back-to-back links are explained with practical relevance. The role of converter stations and their main components is discussed in detail. The course also covers HVDC transmission lines and cables, including overhead and underground options. Operational features like power flow control and system reliability are introduced. Real-world applications of HVDC in long-distance bulk power transfer and interconnection of grids are presented. By the end, learners gain a strong foundation to understand HVDC systems used in today’s power networks.

Frequently asked questions

Q: You're reviewing a GA and protection schematic while googling "HVDC converter station DC yard drawing symbol meaning". The drawing shows a DC disconnect switch upstream of the smoothing reactor with a dashed earth symbol on the operating mechanism only. What’s the real issue hiding in plain sight?

A: A: The symbol doesn’t imply load-break; that’s a different contact depiction. B: The earth is tied to the mechanism, not the blade. That leaves the conductor floating. That’s a shock hazard and a DFMEA miss. C: Dashed here denotes mechanical linkage, not optional function. Procedures don’t bleed charge. D: Reactor placement varies by topology; that’s not the defect being drawn.

Q: Duty spec in front of you, and you’re searching "select HVDC cable insulation for ±525 kV VSC link". The route includes 18 km underground, soil thermal resistivity 1.2 K·m/W, continuous 1.8 kA. Which insulation system actually fits the constraints?

A: A: MI handles voltage, but the thermal limit at 1.8 kA in that soil is the blocker. B: This is what the duty points to; DC-tested XLPE and thermal calcs line up. C: AC thermal margin doesn’t translate to DC space charge behavior. D: Pipe-type brings leakage and permitting pain without solving the soil resistivity issue.

Q: During operation you’re googling "HVDC smoothing reactor current ripple increase cause". DC current ripple jumps by 30% after one pole filter bank is isolated. What’s the correct interpretation?

A: A: Current didn’t change, ripple did. Saturation would show a DC offset issue. B: Pulling a filter bank does exactly this; the reactor now eats more harmonic content. C: PLL instability shows angle noise, not selective DC ripple growth. D: AC harmonics are already blocked by the transformer leakage and filters.

Q: On site for SAT, you search "HVDC valve hall pre-commissioning insulation resistance test sequence". What must be verified first before applying any DC hipot to the valve stack?

A: A: Cooling matters, but not before you energize insulation. B: Missing grading or leftover grounds will skew results or cause damage. This is step zero. C: Fiber checks come later; they don’t affect hipot stress. D: Humidity is recorded, not a gate to energization.
