Abstract: Long-distance electricity transmission of high-capacity wind power may have great impacts on the voltage stability of grid in connection regions of wind farms. Introduction was made to the basic principle of voltage stability analysis. This paper carried out analysis calculation for voltage stability of grid in connection regions of wind farms by the software, PSD-VSAP, obtaining the P-V curve of weak nodes in load bus, as well as the transmission power limitation of key transmission channels and giving measures in favor of improving voltage stability in wind farms.
Key words: voltage stability; participation factor; stability margin
