Simulation Study on Grid-connection Characteristics of Half-wavelength Transmission Line

为了研究半波长输电线路的并网特性,考虑半波长交流输电线路参数分布特性,分析了半波长并网特性与其他类型线路并网特性的差异性。在MATLAB中搭建了半波长线路并网仿真模型,仿真了不同并网条件下半波长线路的并网特性,并与其他类型线路作对比。仿真结果表明,半波长输电线路并网特性最优,并且调谐至半波长的输电线路具有与自然半波长线路一致的并网特性。

In order to study grid-connection characteristics of the half-wavelength transmission line,parameter distribution characteristics of half-wavelength AC transmission lines was considered,and differences in grid-connection characteristics between half-wavelength lines and other types of lines were analyzed. A grid-connection simulation model was set up in MATLAB for half-wavelength lines,and grid-connection characteristics of half-wavelength lines under different grid-connection conditions were simulated and compared with those of other types of lines. Simulation results showed that the half-wavelength transmission line had the best grid-connection characteristics,and the transmission line tuned to half-wavelength had the same grid-connection characteristics as the natural halfwavelength line.
