Dynamic Security Assessment (DSA) is an important way for ensuring the secure and reliable operation of power systems. The current trend is to perform DSA on line using near real-time data. One of the modeling considerations for DSA is special protection systems (SPS). This paper describes a framework that is designed to model SPS for DSA, particularly with respect to on-line applications. It is based...
Firstly this paper presents the technical aspects of designing a Dynamic Voltage Restorer (DVR) to meet some stringent requirements of voltage sags mitigation for Micro Integrated Power System (MIPS). Secondly through an analysis of configuration of DVR the optimum energy injection scheme is introduced. Thirdly the principles of a control scheme and a protection circuit for mitigating surge current...
