The invention provides a simulated power transmission line for teaching and a method for simulating the power transmission line. The simulated power transmission line for teaching consists of a simulated power transmission line and an artificial line parameter measuring instrument, wherein the simulated power transmission line is used for transmitting the corresponding powder on the power transmission line according to simulated power transmission line target parameters set by users, and the artificial line parameter measuring instrument is used for measuring the target parameters of the simulated power transmission line after a correct measuring loop is built between the artificial line parameter measuring instrument and the simulated power transmission line. The simulated power transmission line for teaching and the method for simulating the power transmission line provided by the embodiment of the invention are mainly used for high-voltage laboratories for simulating the testing on items such as positive sequence impedance, zero sequence impedance, positive sequence capacitance and zero sequence capacitance of the line of a high-voltage power transmission line. During the testing, different line parameters and different line lengths can be set any time. Meanwhile, no high voltage is output in the whole process, and safety and reliability are realized.
Description
technical field [0001] The invention relates to the field of electric equipment, in particular to a simulation transmission line for teaching and a method for simulating the transmission line. Background technique [0002] Due to the continuous development of the power system and the continuous operation of high-voltage and ultra-high-voltage transmission lines, in order to provide accurate line parameters for relay protection, it is necessary to measure the line parameters of the transmission lines. [0003] Line parameter measurement of high-voltage and ultra-high-voltage transmission lines is a job with complex procedures and strong technical requirements, and there are certain safety risks. Therefore, in order to do a good job in line parameter measurement, it is necessary to carry out technical training for high-voltage test personnel participating in line parameter measurement. Since high-voltage and ultra-high-voltage transmission lines have strict power outage time ...
