چکیده

The fault current development in a circuit breaker during a pole-to-ground fault is analyzed for a generic multiterminal HVDC system based on Voltage Source Converters. The paper aims to contribute to the current discussion of which requirements on breaking time and peak current HVDC circuit breakers need to fulfill in such networks either based on OHLs or cables. Therefore, the fault current is broken down into the individual contributions of the different network components and their influence on the development of the fault current in the circuit breaker of the faulted line is illustrated. In doing so, the emphasis is on the comparison of the sensitivities in cable and OHL systems.

Fault Current Characterisation in VSC-based HVDC Systems

The DC-side line faults in high-voltage direct-current (HVDC) systems utilising voltage-source converters (VSCs) are a major concern for multi-terminal HVDC systems in which complete isolation of the faulted system is not a viable option. A number of challenges are posed by both pole-to-pole and pole-to-ground faults including the presence of very fast and high amplitude discharge current from ...

Multi-Terminal HVDC Networks - What is the Preferred Topology?

This paper investigates the influence of the DC network topology with respect to two important aspects: the steady-state losses and the transient fault currents. For this, the optimal power flow in a combined AC-DC Multi-Terminal HVDC cable system based on Voltage Source Converters and the development of prospective fault currents during a pole-toground fault is simulated. The results prove tha...

One Terminal Digital Algorithm for Adaptive Single Pole Auto-Reclosing Based on Zero Sequence Voltage

This paper presents an algorithm for adaptive determination of the dead timeduring transient arcing faults and blocking automatic reclosing during permanent faults onoverhead transmission lines. The discrimination between transient and permanent faults ismade by the zero sequence voltage measured at the relay point. If the fault is recognised asan arcing one, then the third harmonic of the zero...

Internal Fault Detection, Location, and Classification in Stator Winding of the Synchronous Generators Based on the Terminal Voltage Waveform

In this paper, a novel method is presented for detection and classification of the faultyphase/region in the stator winding of synchronous generators on the basis of the resulting harmoniccomponents that appear in the terminal voltage waveforms. Analytical results obtained through DecisionTree (DT) show that the internal faults are not only detectable but also they can be classified andthe rela...
