半波长输电线路调谐电路接线形式及零序回路补偿
Connection Form of Half-wavelength Transmission Line Tuned Circuit and Compensation Necessity for Zero-sequence Circuit
摘要
Abstract
By an analysis of the influence of different compensating schemes on voltage distribution along half-wavelength line,it is hoped that an ideal half-wavelength compensating scheme can be obtained.A conclusion is derived by mathematical derivation process that the line to line circuit and zero sequence circuit should both be considered in the compensation scheme for complete simulation of the transmission of the three-phase transmission line.The simplified tuned circuit model with zero-sequence compensating is proposed and voltage distribution along the line of natural half-wavelength,tuned half-wavelength with and without zero-sequence compensating is simulated under conditions such as on load,no-load and open-phase running.The voltage distribution along the line without zero sequence compensating exhibits superposition of line to line circuit and zero-sequence circuit,which is much different from natural half-wavelength.As a result,the tuned circuit with zero-sequence compensating is better able to simulate the characteristics of natural half-wavelength line.关键词
