“…1 is modeled on EMTP-RV. The supervisors are converted into C code and implemented in this software according to the method described in [9]. We simulate a pole-to-ground fault on the BD cable at time t = 1s.…”

“…In recent years, examples of its use can be found in AC distribution systems, such as the implementation of power management strategies in microgrids [6] and the control of custom power parks [7]. In HVDC systems, the SCT has been used to control an on-load tap-changing transformer [8] and the start-up procedure of a point-to-point HVDC link [9]. The new application of SCT presented in this paper brings a reconfigurable supervisory control system [10], based on the commutation of separately computed discrete controllers that belong to what we call elementary control modes.…”

This paper studies the use of Supervisory Control Theory to design and implement post-fault restoration schemes in a HVDC grid. Our study focuses on the synthesis of discrete controllers and on the management of variable control rules during the execution of the protection strategy. The resulting supervisory control system can be proven "free of deadlocks" in the sense that designated tasks are always completed.
