摘要：Voltage controls in multiple wind farms which are located closely interact with each other due to the electrical connection. This paper poposes a small-signal model to reveal the mechanism of voltage control interactions. The significant influences of the interactions on dynamic voltage stability are carefully discussed. Negative damping component caused by interactions deteriorate dynamic voltage stability under weak grid conditions. The analysis shows that two factors, grid strength and control parameters, have great influence on the interactions. The system stability can be threatened when large-scale wind farms integrate into a weak grid and control parameters is set unproper for the system operation. Finally, time domain simulation results are presented to validate the phenomenon and the effects of the two facors.
