Fuzzy Logic Technique for High Impedance Fault Detection in Distribution Feeder
The distribution feeder faults need to be detected and isolated in a reliable Maintenance and operation of a distribution type electrical power system, calls for a safe, reliable and efficient fault detection systems. As the number of techniques available to detect faults do not address the above concerns in to-to, especially in the case of a High Impedance Faults. Keeping in view of aforesaid ...
متن کاملDetecting High Impedance Fault in Power Distribution Feeder with Fuzzy Subtractive Clustering Model
An irregular activity on electric power distribution feeder, which does not draw adequate fault current to be detected by general protective devices, is called as High impedance fault (HIF). This paper presents the algorithm for HIF detection based on the amplitude of third and fifth harmonics of current, voltage and power. This paper proposes an intelligent algorithm using the Takagi SugenoKan...
متن کاملCross Entropy-Based High-Impedance Fault Detection Algorithm for Distribution Networks
The low fault current of high-impedance faults (HIFs) is one of the main challenges for the protection of distribution networks. The inability of conventional overcurrent relays in detecting these faults results in electric arc continuity that it causes the fire hazard and electric shock and poses a serious threat to human life and network equipment. This paper presents an HIF detection algori...
متن کاملRESONANT GROUNDING A. Principals of the resonant grounding In medium-voltage (MV) and high-voltage (HV) networks with “resonant grounding” the current over the fault location in the case of a single line-to-earth-fault (SLE)
Theoretical Electrical Engineering August / 2001 Page 1 / 7 Abstract--In this paper we present a new method for the control of Petersen coils in resonant grounded networks. The major problem for the tuning at small neutral-to-earth voltages is to distinguish between resonance points simulated by the disturbances and real resonance points. In addition the controller has to recognize network modi...
متن کاملHigh Impedance Fault Detection On Distribution Feeders
The ability to detect High Impedance (HiZ) faults has been a topic of research and development for over 30 years. About seven years ago, products began to appear on the market that could securely perform this function. Over this time period, several hundred HiZ detection devices have been placed in service and have performed to expectations. This paper reviews the operating principle of HiZ fau...
