Special Issue Information

Dear Colleagues,

At present, an efficient, interconnected, and resilient power system that deals with distinct and evolving challenges is required. HVDC grids are foreseen to reinforce the existing power system and to enable the integration of renewable resources on a bulk scale. Flexible HVDC technology can provide essential functionalities based on its inherent characteristics, such as fast power flow control capability.

This Special Issue is dedicated to HVDC grids. Therefore, we invite original papers addressing the various topics related to HVDC grids. The topics of interest include but are not limited to:

  • HVDC system development, analysis, and design, including converter stations, MMC, DC–DC converters, semiconductor device developments, transmission links;
  • DC-interconnected offshore wind power plants;
  • Grid services, frequency support;
  • HVDC grid control, including adaptive control, grid forming and grid following control;
  • Stability analysis and harmonic interactions;
  • Protection of HVDC grids, covering HVDC breaking devices, fault ride through, protection algorithms, protection schemes;
  • Field experience with HVDC systems.

In this paper, the traveling wave protection issue of a hybrid high-voltage direct-current transmission line based on the line-commutated converter and modular multilevel converter is investigated. Generally, traveling wave protection based on voltage variation criterion, voltage variation rate criterion and current variation rate criterion is applied on hybrid high-voltage direct-current transmission lines as primary protection. There are two issues that should be addressed: (i) it has no fault direction identification capability which may cause wrong operation regarding external faults; and (ii) it does not consider the difference between line-commutated converter based rectifier station topology and modular multilevel converter based inverter station topology. Therefore, a novel traveling wave directional pilot protection principle for the hybrid high-voltage direct-current transmission line is proposed based on the S-transform. Firstly, the data processing capability of S-transform is described. Secondly, the typical traveling wave propagation process on a hybrid high-voltage direct-current transmission line is studied. Thirdly, a novel traveling wave fault direction identification principle is proposed. Eventually, based on PSCAD/EMTDC, a typical ±400 kV hybrid high-voltage direct-current transmission system is used for a case study to verify its robustness against fault location, fault resistance and fault type.

Recently, in order to overcome the difficulties of interrupting fault currents in multi-terminal direct current systems (MTDC), studies combining a saturated iron-core type superconducting current limiter (SFCL) and a direct current circuit breaker (DCCB) have been conducted. However, the effect of inductance change of the SI-SFCL on the interrupting time of the DCCB during fault has not been studied yet. In this paper, the interrupting time delay caused by the dynamic behavior of the inductance change during the fault current blocking process of the SI-SFCL combined with a DCCB was analyzed through experiments and a new fault detection method considering this phenomenon was proposed. After designing and manufacturing the laboratory-scale SI-SFCL and DCCB, a fault current interrupting test was performed and the inductance change pattern of the SI-SFCL was analyzed. Based on the analysis results, a new fault detection technique was proposed to alleviate the interruption time delay that occurs when applying the combined protection system to a MTDC, and its effectiveness was verified through a simulation. These results will be useful for planning protection coordination strategies when introducing a SI-SFCL in combination with a DCCB in actual MTDC systems. Full article
