Research on the Operation Mode Construction and Stability Control Measures of Half-WaveLength Transmission Test System

The half-wavelength transmission technology is a super long distance transmission mode with strong competitiveness and good application prospects. Compared with conventional AC transmission projects, the half- wavelength transmission line has highly different transient and steady-state characteristics. Therefore, it is very necessary to carry out engineering test before the construction of half-wave length transmission project. Focusing on the two kinds of stability problems with the half-wavelength transmission line put into operation, the basic selection principles for the half- wavelength transmission test line are proposed in this paper. And based on the electric power planning network frame of the Western China, three construction schemes of half-wavelength transmission test lines are put forward. According to the situation of grid structure and power supply nearby, the operation mode of half-wavelength transmission test system is arranged. And influence on the stability characteristics of the regional power gird with different construction schemes of test systems are analyzed by simulation calculation. Further, relevant stability control measures are put forward to ensure the safe and stable operation of test system and near area power grid.
