In this paper, while dynamically evaluating the capabilities of Static Inter phase power controller (SIPC), its effect on the transient stability of a sample power system has been investigated, as well as a technique based on its discontinuous control has been presented to improve the stability of the system. The research method is based on the computational solution of the dynamic equations of the system, the repetition of the simulation stages, the calculation of the critical clearing time (CCT) and the determination of the  peak overshoot generated in the rotor angles of the machines due to a symmetrical three-phase short-circuit fault. For this purpose, the system and the related device were simulated in the DIgSILENT software envierment and the research issues were followed by considering multiple scenarios. In this regard, first all the capabilities of the device were confirmed in the time domain, and then the transient stability limit of the system with and without it was investigated and compared, resulting in a relative decrease in the transient stability limit of the system. Finally, in order to apply the technique, the main control of the device was transferred to another control called transient control so that the transmitted power of accelerated machines can be maximized within the time interval after the fault clearing, which ultimately results in a relative improvement in the transient stability limit of the system.
