Mechanism Analysis of the Stator Inter-tum Short Circuit Fault of New Synchronous Condenser

With the large-scale operation of the new synchronous condenser, the security problem of the Condenser has gradually become prominent. The stator inter-turn short circuit fault is a common serious fault of the condenser, which has a serious impact on the long-term operation of the condenser and the stability of the power grid. In this paper, theoretical analysis and finite element simulation are used to analyze and verify the influence of the fault on the current amplitude and phase of the two branches of the faulted phase, and to provide mechanism analysis and help for fault diagnosis.
