A new protection algorithm for DC line faults in multi-terminal high voltage (MTDC) systems is proposed this study. four-terminal MTDC model used to investigate fault behaviour and detection using the simulation program PSCAD/EMTDC. The results are post-processed Matlab. clearing must be done very rapidly, limit effect of on neighbouring lines because rapid increase current. However, before line, location detected as soon possible. therefore needed, preferably without communication. study...
This paper deals with nonunit protection of HVDC grids by proposing a set parameters that characterizes the open zones together an efficient method to determine thresholds on these parameters. Selective grid schemes must detect and discriminate faults within first milliseconds fault transient consequently differ considerably from existing ac schemes. Due accompanying speed requirement, primary is expected be based as communication delay impedes fast operation. In this paper, principles...
The use of direct current (dc) power networks, either at high voltage or medium voltage, is being increasingly seen in modern smart grids. This due to the flexible control possible with dc and its ability transmit distribute under circumstances where alternating (ac) networks are unable to, less economic. paper provides an overview evolution high-voltage (HVDC) transmission from early Thury systems, ultrahigh-voltage multiterminal voltage-source converter systems. operation both...
This paper examines the current status of technology and discusses technical options for developing DC transmission grids. The fast advances in VSC HVDC, recent offshore projects, experience with multiterminal HVDC development circuit breakers bring large meshed grids closer to reality. most important difficult remaining challenge is system level protection article further some ongoing research directions like use travelling wave detection or deployment DC/DC converters isolation faults. One...

The purpose of this paper is to give a short overview existing technologies regarding phase shifting transformers (PST's). A classification made based on the symmetrical or asymmetrical and direct indirect character PST. As case-study, PST's in Meeden, Netherlands are studied more profoundly. Furthermore, model developed real-time digital simulator (RTDS) order demonstrate capabilities PST
DC power flow is a commonly used tool for contingency analysis. Recently, due to its simplicity and robustness, it also becomes increasingly the real-time dispatch techno-economic analysis of systems. It simplification full looking only at active power. Aspects such as voltage support reactive management are possible analyse. However, simplifications cannot always be justified sometimes lead unrealistic results. Especially implementation controlling devices not trivial since standard...
Abstract Voltage source converter high voltage direct current (VSC HVDC) is a relatively new technology which allows the connection of islanded power systems.
