Evaluation of Critical Clearing Time of Power System Equipped with a Static Synchronous Compensator
Problem statement: The critical clearing time provides very important role of the robustness in power system. The Static Synchronous Compensator (STATCOM) has been accepted to be equipped in modern power system. This study presents the method to evaluate the Critical Clearing Time (CCT) of the system equipped with a Static Synchronous Compensator (STATCOM). Approach: The parameter on STATCOM is...
متن کاملCritical Clearing Time Evaluation of Power System with UPFC by Energetic Method
This paper describes the use of direct method based on energy function type Lyapunov to evaluate the Critical Clearing Time (CCT) of power system subjected to large contingencies. The two axes model of generator with speed and excitation regulation systems is considered in this study. The power system model takes in consideration the presence of a Unified Power Flow Controller (UPFC). An energy...
متن کاملSimulation-free Estimation of Critical Clearing Time
Contingency screening for transient stability of large scale, strongly nonlinear, interconnected power systems is one of the most computationally challenging parts of Dynamic Security Assessment and requires huge resources to perform time-domain simulations-based assessment. To reduce computational cost of time-domain simulations, direct energy methods have been extensively developed. However, ...
متن کاملDetermination of Accurate Critical Clearing Time for Transient Stability Assessment
Transient Stability Assessment (TSA) is essentially important since recent blackout in northern India turns most of the research people towards dynamic security. Transient stability is inherently a Differential-Algebraic equation which is needed to be tackled by an effective method. So, Time Domain Approach is implied in solving TSA.The main objective of this paper is to determine accurate Crit...
متن کاملDesign Features of a Real-Time Check-Clearing System
operations often require complex facilities for their data processing. This application required a multiprocessor configuration controlled by a single job step running continuously for many hours a day. Discussed are the special access methods and recovery procedures designed for this environment. The paper also describes a particularly eficient sorting technique evolved for handling large...
