Design and Experimental Study of Traveling Wave Signal Generator for Distribution Network

Abstract

Aiming at the problem of operation safety and stability of electrical equipment in distribution network caused by impulse voltage, this paper will study and analyze the traveling wave signal generator. Through the study of the standard lightning wave shape characteristics and the mechanism and characteristics of the existing lightning impulse voltage signal generator equipment, the working principle of the corresponding traveling wave signal generator was designed and the relevant parameters were calculated. Finally, the results of the research and analysis were simulated and analyzed with the Multisim simulation software. Test results show that the impulse voltage generated by the full wave form basic satisfy the provisions of this design is expected waveform, and consistent with the actual lightning wave shape, therefore, this thesis studies the traveling wave signal generator unit can meet the normal travelling wave signal of traveling wave positioning system requirements, verify the real effectiveness and practicability of this thesis research.
