Transmission network angle stability protectionbased on synchrophasor data in control centre

Angle stability appears in many forms transmission network. There are small active power oscillations which do not endanger the normal operations whereas medium and large have implications on operations. These latter kinds of some cases develop out step condition, is dangerous disturbance with serious impact network generating units. Transmission operator’s challenges obligations to treat right manner angle issues their Controlling protecting needs be done efficient way order disconnect quickly prevent abnormal operation without exporting surrounding networks. Synchrophasor measurements control centre offer a platform, responds new Those collected phasor data concentrators, part Wide Area Monitoring will used for creating protection. This first extended system Protecting And Control (WAMPAC). Paper gives progress such project Croatian Network Operator (HOPS). Firstly, there stated motives development protection based synchrophasor measurements. Some feasibility aspect elaborated emphasis communications latency. Furthermore, designed Matlab model portions simulations results analyses presented paper reveal potential proposed solutions. using voltage angles values from stream concentrator.
