Research on Steady-State Operation Characteristics of UHV Half-wavelength AC Power Transmission Line
摘要
Abstract
Based on sinusoidal steady-state analytical solution of UHV half-wavelength AC power transmission (HWACT) line, the impacts of load characteristics and power factor on its steady-state operation characteristics under inductive load and capacitive load are respectively analyzed. Analysis results show that under normal operation condition, namely severe overload does not occur, the overvoltage level as well as line loss and corona loss of HWACT line are lower than those of traditional transmission lines; the differences of effective values of voltage and current at sending end and receiving end are small, and phase angle of voltage as well that of current at sending end and receiving end are basically reversed. Under the condition of overload, overvoltage appears at the middle of HWACT line. The higher the power factor, the more stable the voltage and current of HWACT line.关键词
