In order to meet the current situation of the strong growth of energy demand,
the authors put forward the research of thermal energy storage technology
and its application in power data remote transmission. The main content of
the technology is based on heat energy storage technology, discuss the
advantages of heat energy storage technology, and study the stability
analysis in the remote transmission of power data, finally, the stability
performance of heat energy storage technology in power data remote
transmission is obtained through experiments. The experimental results show
that the energy storage is added at bus 6 of the power supply end, and the
transmission distance between the energy storage power station and bus 6 is
changed and the energy storage output is kept at 100 MW, the power of the
connecting line is 400 MW. With the increase of the transmission distance,
the variation trend of the interregion oscillation mode and the oscillation
mode in Region 1 and Region 2 is that the oscillation frequency increases,
the characteristic root moves to the left and the damping ratio increases,
but the change is small. In conclusion it proves that heat energy storage
technology has outstanding advantages, it has a broad development prospect
and an important role in power data remote transmission.
