“…Through the simulated fault at 2 sec, a 28.76 kA fault current was generated, and a 477.40 kV voltage appeared across the circuit breaker. As mentioned earlier, the oscillation current flowed into the breaker circuit and created the zero current point according to (1)(2)(3)(4). This reduced the magnitude of the voltage and current in the breaker circuit, and the residual voltage was discharged through the lightning arrester.…”

“…At 2.01 sec (2010 ms), the circuit breaker conducted the opening operation. As soon as the circuit breaker opened the circuit, the oscillation current flowed into the breaking circuit, and an artificial zero appeared according to (1)(2)(3)(4) where U arc means the arc voltage across the circuit breaker in the breaking circuit and w c means the frequency of the oscillation circuit.…”

“…The breaking capacity and time of the DC circuit breaker, which is the protection equipment for the grid, is an important element in improving the stability and reliability of the HVDC system. The DC current has no zero current point, and a high arc voltage appears across the DC circuit breaker when it conducts breaking operation [1][2][3][4]. If a high arc voltage damages the insulation or if the burden on the circuit breaker exceeds the breaker's circuit breaking capacity, it can lead to a blackout, or in the worst-case scenario, to the collapse of the entire grid.…”

In this study, a SFCL-combined DC circuit breaker system was proposed by applying the current-limiting technology for DC circuit breaking. The SFCL-combined circuit breaker system consists of a mechanical DC circuit breaker combined with superconductors. To ensure the reliable structure and operation of the SFCL-combined circuit breaker system, a simulation grid was designed using the EMTDC/PSCAD program, and simulation was conducted. The results showed that the SFCL-combined DC circuit breaker system with superconductors limited the maximum fault current by 37%. In addition, the burden on the DC circuit breaker was decreased by 87%.

“…A self-commutated voltage source converter high-voltage dc (VSC-HVDC) transmission system presents a competitive alternative to the LCC-HVDC transmission system, for transmitting power over long distances, without the commutation failure shortcoming of the LCC systems. However, converter topologies employed in the early VSC-HVDC transmission systems limit their power rating and dc operating voltage to 500 MW and ±200 kV (symmetrical mono-pole), which are much lower than that of LCC-HVDC links [9,[22][23][24][25][26][27][28][29][30][31]. To increase the power handing and dc operating voltage of VSC-HVDC transmission systems, modular and hybrid multilevel voltage source converters have been adopted in preference to traditional two-level and neutral-point clamped (NPC) converters [32][33][34][35][36][37][38].…”

Abstract-This paper connects several modular multilevel converters to form multi-pole VSC-HVDC links which are suited for bulk power evacuation, with increased resiliency to ac and dc network faults. The proposed arrangements resemble symmetrical and asymmetrical HVDC links that can be used for bulk power transfer over long distances with reduced transmission losses, and for the creation of multi-terminal super-grids currently being promoted for transitional dc grids in Europe. The technical feasibility of the proposed systems is assessed using simulations on symmetrical and asymmetrical tri-pole VSC-HVDC links, including the case of permanent pole-to-ground dc faults. I. INTRODUCTIONSeveral ultra-high voltage dc (UHVDC) transmission systems based on the current source line commutating converter (LCC) with dc operating voltages up to ±800kV (800kV per pole) and 7200MW rated power have been installed to supply mega cities [1][2][3][4][5][6][7][8][9]. The choice of LCC is mainly driven by the established track record of LCC in bulk power evacuation over long distances for over 50 years. Proper operation of an LCC-UHVDC link with such large power rating requires the inverter side to be connected to a strong ac network in order to prevent converter commutation failure during ac network disturbances [10,11]. LCC-HVDC links consumes large reactive power that can reach to 50% or 60% of the transmitted dc power, and it varies with the magnitude of dc power being exchanged between two ac networks [9,12,13]. Filter capacitors plus dedicated switched shunt capacitors are widely used to compensate the reactive power of the LCC in a discrete fashion, but this has proven to cause significant instantaneous reactive power mismatch at the filter bus that can create large over-voltages in weak ac networks. This drawback has been avoided in recent LCC-HVDC transmission links installations by replacing the switched capacitors with a line commutating dynamic reactive power compensator that autonomously and seamlessly adjusts its reactive power output in an attempt to maintain constant voltage at the filter bus [6-8, 12, 14-21].A self-commutated voltage source converter high-voltage dc (VSC-HVDC) transmission system presents a competitive alternative to the LCC-HVDC transmission system, for transmitting power over long distances, without the commutation failure shortcoming of the LCC systems. But converter topologies employed in the early VSC-HVDC transmission systems limit their power rating and dc operating voltage to 500MW and ±200kV (symmetrical mono-pole), which are much lower than that of LCC-HVDC links [9,[22][23][24][25][26][27][28][29][30][31]. To increase the power handing and dc operating voltage of VSC-HVDC transmission systems, modular and hybrid multilevel voltage source converters have been adopted in preference to traditional two-level and neutral-point clamped (NPC) converters [32][33][34][35][36][37][38]. Modular and hybrid multilevel converters allow dc operating Multi-Pole Voltage Source Converter HVDC Transmissi...

Abstract-This paper investigates reliability and economic challenges when large amounts of renewable generation are located long distances from load centers. Considering the distance, existing network, economics and controllability requirements, the optimum transmission system may be a multiterminal HVDC with line commutated converter (LCC) and voltage source converter (VSC) stations. The LCC, VSC and multi-terminal HVDC system has been modeled and studied in PSS/E and MATPOWER software platform. The South East Australian test system has been simulated in OPF to investigate the integration of large scale geothermal power into the Australian National Electricity Market (NEM). The sensitivity of the simulated results to variations in generation capacity and system load have been assessed and provide the frontier of the reliability and cost-benefit analysis.
