Buckling restrained bracing systems are effectively being used to reduce seismic response during recent years. But often configurations of these systems are ignored while evaluating their behavior. Aim of this study is to consider the effect of different bracing patterns on the behavior of Buckling Restrained Braced Frames (BRBFs). Multi-storey braced frames with different patterns are modelled. The main variables of this study are the bracing pattern. The effects of bracing patterns on seismic behavior of buckling restrained braces are also considered. The best bracing pattern for a specific bay width and storey height in terms of seismic response are suggested finally.

Power systems are continually experiencing fluctuations of small magnitudes. However, for assessing stability when subjected to a specified disturbance, it is usually valid to assume that the system is initially in a true steady-state operating condition. Power system is subjected with the verity of fluctuation in their parameters. So their performance is not stable at all. This fluctuation must be mitigate as possible as under prescribe limit. In HVDC transmission system, power is generated and distributed in AC, only the transmission is done in the DC. During the ac to dc conversion power system observe the inability problems. In this way, it is essential to analysis the power system performance to enhance it. To ensure satisfactory operation and equipment safety, several limits are recognized in establishing the current order: maximum current limit, minimum current limit, and voltage-dependent current limit. Higher-level controls may be used, in addition to the above basic controls, to improve AC/DC system interaction and enhance AC system performance. Here we have adopted the PID (Proportional integral deferential) controller.
