Abstract

±800  kV Mengxi-Hubei UHVDC transmission lines will be built in 2017, which will have formed a UHADC parallel power system with the existing UHVAC transmission lines in Hubei province. It will have a great influence on the structure and operation characteristics of Hubei power grid. Based on the operation during high flow periods and planning capacity of power delivering of Hubei power grid in 2017, the network structure model was set up with using PSASP software. The continuation power flow (CPF) algorithm was used to calculate the power transfer limit of Mengxi-Hubei UHVDC transmission lines. The stability of Hubei power grid was verified with the Mengxi-Hubei UHVDC transmitting limit power, which included static security analysis, transient stability check of single and serious fault.

Key words

Hubei power grid / power transfer limit / continuation power flow algorithm / stability check
