In terms of reinforcement to meet the minimum requirement for HVDC connection, several aspects can be considered. The AC side can be reinforced by increasing its voltage level, boosting its line rating (through a larger cross section), and/or installing new transmission lines. Existing AC lines ...
AC line-to-ground fault; estimation of dynamic variations in DC voltage and current; Jeju–Haenam HVDC system; PSS/E simulation environment1. Introduction In recent years, high voltage direct current (HVDC) technology has attracted growing attention for power transmission between networks. The first...
corona discharges around the conductor were measured by means of a data acquisition prototype system equipped with a metal electrode device for the purpose of corona current measurement. The signals collected were subjected to digital signal processing parameters to extract the most relevant information ...
Consequently, it becomes imperative to propose an overvoltage assessment methodology for a multi-send HVDC system incorporating wind turbines, aiming to provide a clear direction for future research endeavors. Regarding the rectifier side of the HVDC transmission system connected to wind power, the ...
Versions Notes Abstract The power system is going through a change in its very foundations. More and more power converters are being integrated into the electric grid to interface renewable energy resources and in high-voltage direct-current (HVDC) transmission systems. This article presents a discus...
In the PSCAD/EMTDC software environment, a two-terminal model of the MMC-HVDC transmission power system was simulated for this study. The system parameters of the operating environment and the MMC are shown in Table 2 [33]. Table 2. Parameters of MMC [33]. The data recorded for this ...
A two-terminal simulation model of the MMC high-voltage direct current (HVDC) transmission power system using PSCAD/EMTDC software was used to validate the proposed framework for MMCs faults diagnosis in HVDC transmissions. In each experiment, we have examined the effects of using a normalisation ...
The simulations are carried out under two different scenarios to verify the performances of the proposed HCB. The first scenario is under the temporary fault while the second scenario is under permanent fault on the middle of the DC transmission line at 0.5 s. ...
The premise that the power transmission system is predominantly inductive is adopted, that is, X R ≫ 1. Figure 5. Representation of a three-bus hybrid multi-infeed system. In this paper, the Hybrid Power Voltage Interaction Factor is defined. The h PVIF nk is a new parameter for ...
