“…In the event of a short circuit fault, the voltage drops abruptly at the fault moment, producing TWs which propagate toward both terminals of the transmission line. The amplitudes of initial generated voltage and current waves depend on the line surge impedance ( Z c ) and the fault resistance ( R f ) as follows:

V = - \frac{Z_{c}}{Z_{c} + 2 R_{f}} V_{f}

I = \frac{1}{Z_{c} + 2 R_{f}} V_{f}

where V f is the instantaneous magnitude of the voltage at the fault moment. This characteristic of the fault event could be used as a criterion for discrimination between faults and other stressed conditions.…”

Summary This paper presents a new algorithm for discrimination of short‐circuit faults from power system stressed conditions. The proposed algorithm is based on the combination of distance relay zone‐3 operation and traveling waves generated by either the fault or circuit‐breaker switching. By pick‐up of the distance relay zone‐3, the algorithm looks for traveling waves arriving from the fault point in the first stage. If a fault generated traveling wave is detected, it would be concluded that a fault has occurred. Otherwise, the algorithm enters the next stage and waits for arriving traveling waves caused by open‐switching of the faulted line remote circuit‐breaker. If any traveling wave is detected, the system is under fault condition. Otherwise, the reason of zone‐3 pick‐up is due to a stressed condition. Training a decision tree‐based classifier with the proposed features and simulating the method demonstrate that the proposed algorithm is able to provide a reliable remote back‐up scheme for protection of transmission lines.

“…Communications in protection inherently slow down the process of restarting the transmission system after a fault event. Communications are also expensive especially for transmission and can be unreliable [6]. For the purpose of faster fault isolation and system restart, it is desired to design a protection coordination scheme that does not utilize a communications channel between converter stations.…”

“…For the purpose of faster fault isolation and system restart, it is desired to design a protection coordination scheme that does not utilize a communications channel between converter stations. Examples of noncommunication relay coordination protection designs are found in [6]- [8]. In each of these cases, relay protection is dependent upon detection of local circuit breaker operational states.…”

This work addresses the protection of a high voltage DC (HVDC) transmission system, utilizing the modular multilevel converter (MMC) topology in addition to incorporating a hybrid transmission corridor (transmission line including overhead line and cable sections). A solution is proposed for identifying the section within which a DC fault is located for the purpose of maintaining power delivery. A detailed model of the MMC-HVDC system is simulated using PSCAD, and an in depth fault analysis is performed. A characteristic signal is discovered and then implemented into a novel solution. The end result is a fault section identification protectionalgorithm, implementing protective relay coordination to protect the system from false circuit breaker reclose as well as enabling fast system restart for nonpermanent faults. This restart protection algorithm is implemented without the use of a communications channel between converter stations, introducing novelty and quick restart response.

“…Even today, in modern microprocessor relays, the mentioned algorithm is used to discriminate direction of fault . Phase angle of positive‐sequence impedance, difference phase angle of postfault current and a reference current signal, and negative‐sequence of current and voltage signals are some attractive approaches of this group. In the following, some advantages and disadvantages of these algorithms are presented: In general, algorithms of the second group are funded on fundamental frequency, estimated using discrete Fourier transform (DFT).…”

Summary Connection of distributed generations (DGs) to distribution networks changes their radial construction to mesh type and increases fault current level. In order to prevent over current relay tripping in case of out‐of‐zone faults, direction of faults must be determined. On the other hand, fault current limiters (FCLs) are a suitable technique to reduce the issue of fault current increasing. In this paper, it is confirmed that operation of FCLs affects voltage and current signals, drastically. Since fault direction is detected by directional relays using these signals, hence, FCLs can affect the performance of the relays. In the other hand, if the added DG is a wind turbine, it may affect the directional relays performance due to intricate fault behavior of wind turbines. To investigate the mentioned hypothesis, some of directional relaying algorithms are evaluated in presence of wind turbine and FCL.
