摘要： A method, system and apparatus of fault detection in line protection for a power transmission system. A voltage (u) at a measurement point on an electrical line is obtained. The measurement point is a point at which a protection device for the line protection is installed. A current (i) at the measurement point is further obtained and a differential value of the current is determined. Then, a voltage (u q ) at a setting point on the electrical line is determined from the voltage (u) at the measurement point, the current (i) at the measurement point and the differential value of the current (i) according to a time domain lumped parameter model for the electrical line. The voltage change between the determined voltage at the setting point during the fault period and a voltage at the setting point determined during a pre-fault period can be further determined. The fault detection can be performed based on the determined voltage change and a fault threshold. It can ensure voltage determination accuracy and detection reliability with a low sampling rate. Moreover, the solution can work right after the fault inception, almost no waiting time is required, and thus it may achieve a super-fast line protection.

摘要： It provides a method for detecting fault direction of transmission line (10) of an AC power system (1) and a control system using the same. The method includes sampling current values and voltage values at one end of the transmission line (10) for a series of time points； computing instantaneous voltage values at compensated point on the transmission line (10) from the current value samples and the voltage value samples based on a time domain lumped parameter differential equation for the transmission line (10) for the series of time points； recording the current value samples and the computed instantaneous voltage values at the compensated point； computing at least one voltage fault component each using the recorded computed instantaneous voltage values for at least two of the series of time points； computing at least one current fault component each using the recorded current value samples for the at least two of the series of time points； identifying the fault direction in consideration of the at least one computed voltage fault component and the at least one computed current fault component； and generating a fault direction signal indicating the identified fault direction. Where a fault directional element is designed using the voltage fault components at the compensated point, it will work well for the AC power system (1) with strong power source.

摘要： It provides a method for detecting fault in a power transmission line of a power transmission system and protection system using the same. The method includes steps of: obtaining a system parameter of the power transmission system, adjusting protection reachability of a fault detecting element based on the obtained system parameter such that the adjusted protection reachability of the fault detecting element is applicable to a predetermined protection range, identifying whether there is an internal fault occurring on the transmission line using the adjusted fault detecting element, and generating a fault detection decision signal indicating the identified fault. If the predetermined protection range is desirable for the fault detecting element, its protection reachability may be adjusted in consideration of the influence imposed by the SIR such that the reach point of the adjusted fault detecting element can be extended to approach the end of the predetermined protection range. Consequently, the influence on its accuracy by various SIR values can be taken into account and accordingly the fault detecting solution can remove substantial errors as a result thereof.

摘要： A method for detecting a disturbance in a power system (1) within a digital substation and an apparatus using the same. The method includes: sensing electrical parameters at an end of a transmission line (10); sampling the sensed electrical parameters; extracting traveling-wave information from high frequency component of the samples using a signal processing method; and if the extracted traveling-wave information indicating occurrence of the disturbance, transmitting the extracted traveling-wave information to an intelligent electronic device of the digital substation (11) from a merging unit (112) or non-conventional instrument transformer of the digital substation (11). As compared with the amount of the sample data of the sensed electrical parameters, the amount of the data representing the extracted traveling-wave information is reduced. Thus the extracted traveling-wave information can be transmitted via a data link with a relatively narrow bandwidth, such as the process bus under standard IEC 61850.
