11 HVDC Converter Topologies
12 Conventional HVDC Transmission Tried and tested technology (50 year history) State of the art 132kV, 6400MW, 2000km Problems: Converter station footprint (filters approx 50%) Inability to work on dead networks - voltage needed for commutation of thyristors Limited scope for reactive power control Power reversal requires DC voltage reversal - Limits usage to certain cable types No scope for multi-terminal DC operation +V DC AC System Filter Upper Valve Group DC System Converter Transformer Lower Valve Group Ground Based on line commutated converter (LCC) thyristor technology
13 Voltage Source Converter (VSC) HVDC transmission Voltage source converter HVDC is growing rapidly ( 800kV 10GW) Many advantages over conventional HVDC eg: Black start can feed a dead network Active and reactive power control Much smaller filters/no compensation (station footprint much smaller) Constant voltage DC link multi-terminal applications No voltage reversal for power reversal Some key problems for VSC converters Efficiency (switching converter losses) Operation with faulted AC or DC side Scalability (modularity)
14 Amplitude Voltage Source Converter (VSC) HVDC transmission Two-level inverter based on series connected devices Simple concept DC supply (100+kV) One switch A Requires series devices 2-level operation needs relatively high PWM frequency High switching losses (total losses 1.7% per station) Time /s 2-level PWM generates significant harmonics - filtering One phase of 3 shown
15 Amplitude Modular-Multilevel-Converter (M 2 LC) Concept more complex Switching of cells controls BOTH the DC side and AC side voltage Time /s DC SIDE B CELL E dc 2 phases of 3 shown A No bulk DC capacitor No need for series devices Multi-level operation low switching frequency + good harmonic performance Low switching losses (typical total losses 1% per station) Twice the number of devices required compared to 2-level approach Large number of capacitors of significant size Voltage on individual capacitors must be controlled
16 Modular-Multilevel-Converter (M 2 LC) I dc /3 + I AC /2 V dc /2 + V AC DC SIDE B A Multi-level AC voltage V AC and current I AC CELL V dc /2 - V AC E dc I dc /3 - I AC /2 2 phases of 3 shown
17 Hybrid Topologies Combination of: Multi-level wave shaping Series bridges Modest switching frequency Fractional rating low loss Series device wave steering Zero voltage switching Low loss Combination gives: High waveform fidelity Low loss Low device count Semiconductors Capacitors Scale demonstrator design 20MW, 20kV DC, 11kV AC 1200A, 3300kV IGBTs 1.5kV cell voltage
18 Parallel Hybrid Topology H-bridge- soft Switched (low loss) MMC type chain
19 Parallel Hybrid Topology H-bridge- soft Switched (low loss) MMC type chain
20 Voltage [V] Parallel Hybrid Topology Topology has a very low component count compared to many alternatives Chain-Link converters perform wave shaping function Converters outside of main power path => low switching losses Mean Chain-link current typically <20% of DC current H-Bridge converters are zero voltage soft switched Device switching frequency = fundamental frequency Research Topics Theoretical work on energy control (unbalanced supply etc) Closed loop control and Energy management Time [s] Line-Line voltages at the converter terminals
21 Parallel Hybrid Topology Chain-link cell capacitors have a tendency to charge or discharge Have to control the voltage of the individual converter chain-link capacitors Balancing can be achieved with a sorting algorithm based on the characteristics of the chain-link cells in a given chain-link position Change in chainlink cell voltage with the 'virtual position' of the cell in the chainlink for different power factors V c / A 0-1 Chainlink cell Position power factor angle Capacitor Voltage Control one phase with set point = 50V
22 Series Hybrid Topology
23 Series Hybrid Topology - AAC Vcl1 S1 10kV S1 ON S2 ON Vs1 0 ZVS S1 Vs2 10kV V OFF < 20kV Condition for zero energy exchange with chain-links V AC (peak) = 2E DC / Vcl2
24 Series Hybrid Topology - AAC ADVANTAGES Series IGBT switches commutate at near zero voltage Reduce switching losses Improves converter efficiency Series H-bridges can support the AC voltage when there is a DC side fault Actively control AC side current to zero No need to interrupt fault current with AC side breaker Actively control AC current to be reactive Gives option of STATCOM performance during DC side fault
25 Topology Comparisons 2-level converter Half-link M 2 LC Full-link M 2 MC Series hybrid Parallel hybrid Total Semiconductor count (pu) Total submodule DC capacitor rating (pu) Losses ~0.5 <0.25 AC Harmonic performance Hard-switched IGBT valve needed? Ability to suppress DC faults?
26 Summary Power Converters will be an essential part of the future Electrical Energy Grid Renewable Energy Sources are not directly compatible with the grid Requirement for Power Conversion for all power source connections Challenges for Power Converter deployment in the Electricity Grid Cost [both purchase cost and cost of losses] Reliability/availability Current regulations and legacy equipment Many other topologies exist for AC/AC and AC/HVDC Newton-Picarte project between Universities of Nottingham/Talca/Concepcion will look at some alternatives Kick Off meeting was held in Talca a couple of weeks ago!
