摘要：
The paper proposes an analytical examination of the transient synchronization stability (TSS) of a grid-connected wind farm with multiple permanent magnet synchronous generators (PMSGs). The paper establishes the large-signal model of the wind farm comprising of multiple wind turbines during the fault and derives the TSS criterion by using the transient energy function (TEF) method. The TSS criterion can be employed to estimate the TSS of the grid-connected wind farm with multiple PMSGs during the fault analytically. The paper also reveals and analytically explains how various factors may jointly impact the TSS of the wind farm during the fault. The impact of the setting values of current injections of the PMSGs and variation of power collecting lines on the TSS of the PMSG is examined in the paper. Finally, study cases of an example grid-connected wind farm with multiple PMSGs are presented to demonstrate and evaluate the effectiveness and applicability of the derived TSS criterion and hypotheses.
