[ 1 ] - روشی نوین برای تشخیص خطوط بحرانی با پتانسیل ایجاد خروج های پی درپی در شبکه های قدرت
Abstract: Blackouts are among the main threats to the security of electric power systems. Cascading failures are known as the most important agent for creating blackouts. Transmission lines are the basic equipment of power networks that their outage can make subsequent cascading outages. In this paper, based on the application of decision tree a new approach is proposed for online identificatio...
[ 2 ] - Optimal Sensorless Four Switch Direct Power Control of BLDC Motor
Brushless DC (BLDC) motors are used in a wide range of applications due to their high efficiency and high power density. In this paper, sensorless four-switch direct power control (DPC) method with the sector to sector commutations ripple minimization for BLDC motor control is proposed. The main features of the proposed DPC method are: (1) fast dynamic response (2) easy implementation (3) use o...
[ 3 ] - Evaluating the potential of cascading failure occurrence due to line outage in power systems by information theory method and radial base functions
In power systems, a connected topology is created to increase reliability and economic performance. Increasing dimensions of power systems on the one hand and the need to continuously monitor power systems for secure operation on the other challenge the evaluation of power system security. In such conditions, due to economic conditions and considering the fast growth of consumers in a power sys...
