摘要： A method of determining a fault direction parameter of a fault on an AC transmission line 10 of a power distribution system 1 relative to a measurement location 12 of the transmission line 10 is described. The method comprises: measuring by a measurement unit 20 a time- dependent AC current of the transmission line 10 at the measurement location 12, thereby obtaining time-domain current data 80 indicative of the measured current; the measurement unit 20 comprising a current sensor for measuring the current at the measurement location 12 of the transmission line 10 but no voltage sensor; transmitting the current data to a decision logic section 36; obtaining a fault time 81 of the fault on the AC transmission line 10; identifying a first time tl and a second time t2 by identifying a periodically re-occurring feature of the current data 80, such that the fault time 81 is between the first time tl and the second time t2, wherein the periodically re-occurring feature is selected from the group consisting of a zero-crossing, a maximum, a minimum, a highest gradient of the current data; extracting, from the current data 80, an offset indicative parameter 82; 86, 87 indicative of a time offset 8Γ of the current at the fault time 81 wherein the offset indicative parameter 82 is a time interval between the first time t1 and the second time t2; calculating an offset direction parameter by comparing the offset indicative parameter 82; 86, 87 to a non-offset indicative parameter 84; and establishing the fault direction parameter based on the calculated offset direction parameter.

摘要： The invention relates to a method for determining a line section (10) afflicted with an earth fault in a three-phase energy supply network having an isolated or resonant-earthed star point, wherein a zero-phase-sequence system voltage and a zero-phase-sequence system current are detected at both ends of the line section (10) by means of electrical protective devices (13a, 13b) and direction information is obtained therefrom, the direction information specifying whether an earth fault lies in the forward direction or in the backward direction relative to the respective measuring point (12a, 12b). In order to specify a relatively simple method for determining a line section afflicted with an earth fault, wherein the line afflicted with an earth fault can be determined without having to switch off parts of the electrical supply network, a method is proposed, wherein a complex zero-phase-sequence system apparent power is determined from the zero-phase-sequence system voltage and the zero-phase-sequence system current by means of the protective devices (13a, 13b), the direction information is derived from the sign of a component of the zero-phase-sequence system apparent power, the pieces of direction information of both ends are compared to each other, an earth fault on the line section (10) is recognized if both pieces of direction information indicate a forward direction, and an earth fault outside the line section (10) is recognized if at least one piece of direction information indicates a backward direction. The invention further relates to a corresponding electrical protective device (13a, 13b).

摘要： The invention relates to electric line protection for determining the direction in which a fault occurs, which makes use of direct sequence power. For this purpose, a scalar value is calculated on the basis of the pr-fault voltage (V 1 P ), the variation in voltage in respect of that prior to the fault (ΔV 1 ), the variation in strength in respect of that prior to the fault (ΔI I1 ), the direct sequence impedance of the line (Z L1 ), the maximum phase difference between normal voltages at both ends of the line (θ) and the values adjusted by the user (γ, δ), and said value is compared with two pre-set references (K F , K R ), also set by the user, in order to determine the direction of the fault. The scalar value is calculated using expression (I). The decision rule for determining the direction of the fault is as follows: if K F the fault is in the forward direction and if K > K R the fault is in the backward direction.

摘要： A directional element (40) which produces a quantity ζo related to the zero sequence source impedance of a power system relative to the location of the directional element (40), from values of zero sequence current (IR) and an adjusted value of zero sequence voltage (3Vo). The impedance quantity (ζo) is then compared against first and second threshold quantities (Z OF and Z OR ) to identify the direction of a fault. Further, the zero sequence voltage-polarized directional element can be combined with other individual directional elements, induding a zero sequence current-polarized directional element and a negative sequence voltage-polarized directional element to form a universal directional element for unbalanced faults, in which the individual directional elements operate in a particular sequence, with the other directional elements being blocked from operating if a prior directional element in the sequence provides a direction indication.
