Out-of-Step Relays Testing ProcedureThe paper presents out-of-step (OOS) protection device testing methodology under close-to-real power system operation conditions. The power system stability modelling software is used as source of test signals. The accurate modelling of power system in conjunction with dynamical modelling features allows the correct choice of the most reliable OOS protection scheme. Methodology was applied for out-of-step relay "AGNA" testing and device settings verification.

Method Approach

Since the beginning of the last century, power system stability has been recognized as a vital problem in securing system operation. Power system instability has caused many major blackouts. This paper reviewed the previous technical works consisting of various methods of optimization in controlling power system stability. The techniques presented were compared to optimize the control variables for optimization of power system stability. Power system stability enhancement has been investigated widely in literature using different ways. This paper is focusing on SVC performance for enhancing power system stability either through SVC controlled itself or SVC controlled externally by other controllers. Static VAR compensators (SVCs) are used primarily in power system for voltage control as either an end in itself or a means of achieving other objectives, such as system stabilization.The analysis on performance of the previous work such as advantages and findings of a robust method approach in each technique was included in this paper.
