| titleOfInvention | Method for measuring voltage at single phase ground fault in ultrahigh voltage alternating current power transmission line |
| abstract | Disclosed is a method for measuring the voltage at a single phase ground fault in an ultrahigh voltage alternating current power transmission line. The method of the present invention employs a long-term equation for description of the physical characteristics of voltage and current transmission of the ultrahigh voltage alternating current power transmission line, utilizes a fault phase negative sequence current phase angle at where a protection is installed in the ultrahigh voltage alternating current power transmission line to estimate a voltage angle of the single phase ground fault in the ultrahigh voltage alternating current power transmission line, and calculates the voltage at the single phase ground fault of the ultrahigh voltage alternating current power transmission line on the basis of a hyperbolic tangent function relation of voltage drops along the line and distances from fault of the ultrahigh voltage alternating current power transmission line. The present invention employs the long-term equation and single-ended fault phase electrical quantities to implement precision measurement of the voltage at the single phase ground fault in the ultrahigh voltage alternating current power transmission line, and the measurement result is not affected by distributed capacitance, transition resistance, fault location, and load current, thus a high degree of precision in measurement is provided. |
