During the fault of the wind power collection line of the MMC-HVDC system, the amplitude of the fault current may be limited due to the control of the converter, which leads to the severe limitation of traditional protection. In this paper, based on

An isolated power grid (IPG) lacks the support of the external power grid, and a single generator or load accounts for a large proportion of the total capacity. Once transient angle instability, the generator and load shedding is not effectively. Pha

Abstract Phase sequence exchange (PSE) is an emerging emergency control method for power systems. However, PSE will generate impulse current and voltage. In this research, to suppress the impulse of PSE, a phase control method for zero‐current open

Abstract This letter proposes a novel phase sequence exchange (PSE) device. When the generator loses synchronization and the power angle gradually increases, the primary side of the contact line is disconnected and quickly connected in a staggered ph
