As more generation units are put into operation in 2006

the reliability of power delivery and peak load regulation in Hunan power grid will be improved

accompanying with more problems.In this paper

Influence of high power generation transmitted only by 500kV power network on transmission ability in Hunan grid is put forward.The influence of operation of high power generators on power flow and transient stability of Hunan electric network is analyzed.Relative measurements to coordinate high power generator with stable operation of Hunan electric power network are also presented.
