Construction of the Second and Third Defense Lines of UHV AC Grid
This paper introduces the operation characteristics after the operation of 1000kV grid and the present construction of the second and third defense lines of UHV grid.Research has been conducted on the commonly-used devices of UHV grid,such as grid safety and stability control device,out-of-step separation device and fast out-of-step separation device.Suggestion on the construction of the second and third defense lines of UHV grid has been proposed,including configuration scheme and technical requirements.It also takes a typical UHV grid as an example.The research result has great engineering value and practical significance for the construction of the second and third defense lines of UHV grid.
