Abstract

Abstract: Power grid galloping region distribution map is basis of prevention and treatment of transmission lines galloping during construction and operation phases. It plays an important role in power grid operation safety and stability. In addition to frequency method, the meteorological geographical method is used widely in SGCC as a drawing method for galloping region distribution map without consideration of influence from actual lines. In order to reduce galloping meteorological calculation error resulted from daily meteorological data, a new drawing method based on hourly meteorological data is proposed. The application results in Zhejiang province shows the feasibility of proposed method.

Key words: meteorological geographical method, transmission line galloping, distribution map, meteorological data, drawing, power grid safety, calculation error
