Integrating synchrophasor technology for the improvements in system integrity protection schemes under stressed conditions

The power transmission system, in this age, is characterized by ultra- and extra-high voltage AC, and multi-terminal high voltage DC networks. It has a wide-area power network across the nation. It incorporates conventional and ultra-mega-power plants (UMPPs). It also has a submission of increasing penetration due to Renewable Energy Sources (RES). A crucial role is delivered by the system integrity and protection schemes (SIPS) in sustaining guaranteed and safe grid operation. A SIPS also assists efficient grid management during serious power system emergencies. In this article, thorough investigation of the performable capabilities of three influential SIPS in India is made. The shortcomings in ongoing SIPSs got revealed. A proposed methodology eliminates these obstacles. Apperception and vitality of the recommended technique get decided by simulation exercise on an IEEE 10 generators 39-bus test system ingrained with HVDC link in MATLAB. Simulation outcomes accomplished the credibility of the method in defending system integrity. Electrical Transient Analyzer Program (ETAP) is used for the validation of MATLAB results. ETAP has an organizing/investigation mechanism and it is a remarkably convenient interface.
