Power System Security Assessment and Remedial Measures based on the on-line Dynamic Security Assessment System

Abstract

Abstract:The on-line dynamic security assessment system introduced in this paper calculates and assesses power system using high performance parallel cluster and the real time on-line data obtained by intelligent scheduling system, achieving a leap from the offline analysis to the on-line analysis of the power grid. The main structure, function and calculation process of the dynamic security assessment system are briefly introduced, the safety and stability analysis of power grid after serious failures is taken as example, the calculation results show that the dynamic security assessment system can calculate the power grid and propose the corresponding auxiliary decision-making measures timely and effectively, enhancing the emergency handling capacity of power dispatchers in emergency situations, it plays an important role in ensuring the security and stability of power system.
