This paper presents low voltage ride through (LVRT) characteristics analysis of variable speed wind turbine (VSWT) driving a permanent magnet synchronous generator (PMSG). The VSWT-PMSG is becoming very popular these days in wind power application. In some recent studies, the transient stability and LVRT characteristic of VSWT-PMSG has been reported using different types of symmetrical and unsymmetrical...
In a fault-tolerant power system the failures must be detected and isolated saving the operational state of the system. So we propose a model for performance evaluation of the automations from a power system. Fail safe behavior of the automation system is modeled and fuzzy safety measures are computed for the most significant automations types. The automatic closing reserve is a very important automation...
