FEASIBILITY STUDY ON USING SYNCHROPHASOR TECHNOLOGY FOR POWER SYSTEM TRANSIENT STABILITY CONTROL

The rapid progress of synchrophasor technology promotes broad applications of Wide-Area Measurement System (WAMS), and unveils a new era of power system monitoring, analysis and control. This paper investigates the feasibility of one of the most promising applications of synchrophasor, i.e., the Wide-Area Transient Stability Control. After a brief review of the state-of-arts of related technologies, the authors first propose the concept of 揝ynchrophasor Response Based Wide-Area TSC?or SRBWA-TSC. Next the operation principle and system structure of SRBWA-TSC are described in detail. Then some key issues in its implementation are emphatically analyzed, including power angle measurement, transient stability identification and control, response time, communication infrastructure and system reliability. Thereby the feasibility and superiority of applying synchrophasor to power system transient stability control are well demonstrated.
