Detection of Fault in Fixed Series Compensated Transmission Line during Power Swing Using Wavelet Transform
At the time of power swing the measured impedance lies inside the relay operating region. There is undesired tripping of Distance relay during power swing without having any fault. So relay must be blocked & must trip after a fault occur during power swing. This paper presents new technique to detect fault during power swing. In the proposed technique process starts by simulating the double tra...
متن کاملFault Location in Series Compensated Transmission Lines
Due to the integration of modern technology such as electric vehicles, the emphasis is expected to shift from mechanical to electric power. Therefore, the need of increasing the power transmission capacity of the electric grid gets highlighted. Since, the construction of transmission lines is a tedious task owing to legalities, environmental impacts and high costs, the series compensated transm...
متن کاملImproved Symmetrical Fault Detection Scheme during Power Swing
Relays may not perform as intended occasionally due to many complex reasons, which may result in relay misoperation. This paper provides a fast detection scheme for symmetrical fault during power swing based on travelling wave theory and wavelet transform. The implementation of the proposed method is discussed in detail, which covers implementation framework, data requirements, selection of mot...
متن کاملAn Accurate Offline Phasor Estimation Technique For Fault Location In Series Compensated Lines
With the increasing demand of electric power supply, the necessity to transmit more power has become the need of the hour. The excess power can be transferred by building new infrastructure (costly and time taking) or by using series compensation (relatively cheaper and faster alternative). Series compensation is a technique in which line inductance is compensated by placing a capacitor in seri...
متن کاملFault Location in Uncompensated and Series-Compensated Parallel Lines
Accurate and robust fault location algorithm for parallel lines compensated with one three-phase bank of series capacitors in each the line is presented. The algorithm is categorized as one-end fundamental frequency based technique which offsets the series compensation effect and the reactance effect resulting from the remote end infeed under resistive faults as well as takes the countermeasure...
