“…After remaining in an open state while the main DC breaker opens, the fast disconnector will be exposed During zero current and low voltage stress, the mechanical switch opens. After remaining in an open state while the main DC breaker opens, the fast disconnector will be exposed to the recovery voltage determined by the protection level of the arrester banks first [53][54][55].…”

“…Given the rapid advancement of power electronics, a growing number of HVDC projects have been installed across the world. Their reliability and maintenance strategies have a direct influence on the system's service security and, as result, have a significant impact on network operation [55]. Figure 19 shows the impact of the various components on the forced energy unavailability (FEU) indicator, where it can be seen that the converter valves take part in two-thirds of the number of forced outages, resulting in a high requirement for proper maintenance of converter substations, especially converter valves [56,57].…”

High voltage direct current (HVDC) technology has begun to gather a high degree of interest in the last few decades, showing a fast evolution of achievable voltage levels, transfer capacities, and transmission lengths. All these changes occurred in a context in which power system applications are highly dependent on HVDC technologies such as energy generation from renewable sources (e.g., energy generated in offshore wind power plants), power exchanges between asynchronous networks, submarine cables, and long-length transmission overhead lines have become more common worldwide. This paper tries to summarize the current state of HVDC technologies, both voltage-source converters and current-source converters, the main components of converter substations, control strategies, key challenges arising from their use, as well as the future prospects and trends of HVDC applications. This paper represents the first step in setting the background information for analyzing the impact of a VSC-HVDC connection on the stability of the Romanian transmission network during steady-state and dynamic operation.

“…In a word, the emergence of a new topology improves the operational performance of the converter on the whole. In addition to the above characteristics, MMC-HVDC technology is also applied in a wide range of fields, such as grid connection of new energy, asynchronous interconnection of regional power grids, multi-terminal DC power transmission, and the formation of DC power transmission and distribution grids in large and medium-sized cities [16][17][18]. Therefore, research on the MMC-HVDC topology structure, mathematical modeling, parameter selection, vector control strategy, system behavior, and protection strategy in case of failure of the converter station will play a crucial role in engineering application and analysis [19].…”

With the development of power energy technology, flexible high voltage direct current (HVDC) systems with high control degree of freedom flexibility, power supply to passive systems, small footprint, and other advantages stand out in the field of long-distance large-capacity transmission engineering. HVDC transmission technology based on a modular multilevel converter has been widely used in power grids due to its advantages such as large transmission capacity, less harmonic content, low switching loss, and wide application field. In the modular multilevel converter (MMC)-based HVDC system, the protection strategy of converter station internal faults is directly related to the reliability and security of the power transmission system. Starting from the MMC topological structure, this paper establishes the MMC mathematical model in a synchronous rotation coordinate system by combining the working state of sub-modules and the relationship between each variable of the upper and lower bridge arms of each phase of the MMC. It provides a theoretical basis for the design of the MMC-HVDC control system. The causes of the AC system faults and the internal faults of the converter station in the MMC-HVDC system are analyzed, and the sub-module faults and bridge arm reactor faults in the converter station are studied. The sub-module redundancy protection and bridge arm overcurrent protection strategies are designed for the faults, and the correctness of the scheme is verified by Matlab/Simulink.
