Abstract

With the UHV power grid into a period of rapid development, bi-coupled electromagnetic loop network or even 1000kV/500kV/220kV tri-coupled electromagnetic loop network will be widely formed by the receiving end after UHV project landing. Changes in the structure and operation characteristics of grid bring challenges to the security and stability operation of power grid. This paper discusses 3 problems which could cause operation faults in aspects of short circuit current, reactive power and voltage stability and power transfer in network respectively, and gives relevant measures and guidance suggestions to adjust risks which UHV brought in Tianjin .
