摘要

The systems considering current limiting in transient stability analysis manifest as switching systems, yet their switching mechanism is not clear. To address this issue, this paper establishes a dual DC voltage synchronous control (DVSC) system employing Current Saturation Algorithm (CSA) for current limiting. This paper derives the four operating states and the switching boundaries. The stable equilibrium points of the system under different switching states are calculated, and the conditions for the system to stabilize at its original stable equilibrium point after being disturbed are explained. Finally, simulations verify the correctness and effectiveness of the proposed theory.
