Analysis of the Influence of Live High-voltage Line on Other Line Parameters Measurement

高压输电线路作为电网的重要组成部分,其参数测试的准确性会直接影响整个电力系统的可靠性与安全性,因此如何精确测量高压输电线路参数具有其重要的实际意义。对直流电阻、正序参数、零序参数、部分电容以及互感参数五个方面进行研究,基于传统测量方法进行改进,实现高压输电线路的带电测量,并通过理论修正,设立修正项或修正系数,使所测量的参数数据满足相应的工程需求,从而保证电网的正常运作,具有一定的经济与社会效益。

As an important part of power network, the accuracy of high voltage transmission line parameter test will directly affect the reliability and security of the whole power system, therefore, how to accurately measure the parameters of high voltage transmission line is of great practical significance. DC resistance, positive sequence parameter, zero sequence parameter, partial capacitance and mutual inductance parameter are studied. Based on the traditional measurement method, the live measurement of high voltage transmission line is realized, the establishment of correction term or coefficient makes the measured data meet the corresponding engineering requirements, thus ensuring the normal operation of the power grid, and has certain economic and social benefits.
