ABB HVDC converter transformers An integral and key part of HVDC systems
The role of the converter transformer
§ To separate DC and AC network
§ To adopt voltage to converter valve
§ Tapping range for part of the DC voltage and reactive power control
§ Provide inherent reactance necessary for HVDC current commutation/limitation
§ Transmission line or cable § Transformers
& Thyristor valves
§ Smoothing reactor
§ DC Filter
§ Control System § AC filters § Shunt
capacitors
§ AC bus
Typical features of HVDC transformer
§ Large transformer units
§ Exposed to AC and DC Voltages – strong insulation requirements
§ Subjected to Voltage/Current Harmonics
§ Reactive loading and close interaction with HVDC system
From 800 kV to 1,100 kV UHVDC Why a new rated UHVDC?
§ Meeting increasing energy demands
§ Lowering environmental impact
§ Renewable energy sources are often located far from load centers
§ UHVDC 1,100 kV increases capacity up to 25%, a prodigious upgrade from 800 kV UHVDC
§ Even lower transmission losses over long distances

§ Growing demand for electrical power à strong growth of generation & transmission
§ Cost of power increasing à losses should be reduced
§ Global warming à reduce dependance on fossil fuel à more renewable energy to the electrical grid
§ Electricity becoming a tradeable commodity à need to transfer electricty across border
à Hence HVDC technology!
Electric power for everyone The Challenges
