“…As known, these transmission systems enable the possibility of transferring high amount of power over long distances as well as interconnecting large parks of renewable-type generators typically composed of off-shore wind farms. Due to the nature of the HVDC systems, the protection and fault location in HVDC transmission systems are crucial issues [1][2][3] and the major challenge is represented by the need of identifying the faulted line within time windows of few milliseconds.…”

Abstract-This paper aims at proving the application of the fault location method based on the Electromagnetic Time Reversal (EMTR) to multi-terminal HVDC (MTDC) networks. In particular, the paper integrates the EMTR fault location technique with the protection scheme recently proposed within the EU project TWENTIES. Further, in view of the peculiarity of the fast protection schemes required by HVDC applications, the paper discusses the performances of the EMTR-based fault location technique by using limited time-windows over which the fault-generated electromagnetic transients are time-reversed. The paper also discusses the advantage of the EMTR fault location related to the use of a single observation point to the case of MTDC grids. Indeed, such a peculiarity may represent a major advantage avoiding necessary time synchronization between the MTDC-fault recording stations and might represents, also, a backup protection system. The performances of the proposed method are validated by numerical simulations obtained using the EMTP-RV simulation environment where electromagnetic fault-transients are reproduced with reference to the MTDC benchmark network of the project TWENTIES.

“…PSCAD is running to generate data, sampled at 10KHz. The quantities measured at the relay point are influenced by the coupling between the positive line and the negative line, it is required to transform the sampling value of voltage and current at the relay point to independent mode quantities employed in [13]. For this case, the setting distance is taken as 400 Km and the fault has taken place at 0.9 sec with transition resistance of 0 ohm and 150 ohm.…”

“…The voltage and current distributions along the line can be obtained according to [13] Equations (10) and (11) gives the setting point voltage and current, where r is resistance per kilometer, Z 0 and v 0 are characteristic impedance and wave speed respectively. For obtaining the setting point voltage and current u k0 (t) and i k0 (t) linear interpolation in [15] can be used .…”

Abstract-HVDC transmission systems based on voltage source converters have lately emerged as a good alternative to conventional AC transmission. In these transmission systems multilevel converters have become a promising energy conversion technology. The reliability of the power converters are extremely important since a fault in these equipments may lead to an unavailability for a long period of the transmission system. Thus, this paper will focuses in HVDC dual transmission system under semiconductor failure conditions. As presented in this paper this structure presents interesting characteristics under the point of view the reliability considering a power semiconductor failure. It will present the consequences for the transmission system when there is a semiconductor fault. A study for the change of the modulation system in order to ensure DC link capacitors voltage balance under a fault condition is also presented. Simulation studies are shown in order to confirm the characteristics of the proposed methodology in normal and fault condition mode.
