Power System Monitoring using Phasor Measurements

Abstract

The  paper  describes  investigation  of  the  new  opportunities  for  power  system  monitoring  and  control  using  phasor  measurements.  Phasor  measurements  are  used  for  power  system  model  identification  in  the  form  of  state-space  model.  Implementing  the  modal  analysis  to  identified  state-space model gives the opportunity to control proximity of  the  operation  point  to  the  feasibility  boundary.  Also,  identified  state-space  model  allows  predicting  power  system  transient.  All  time  domain  simulations  of  the  research  are  conducted for two-generator-swing-bus system. Calculations were carried out in Matlab.
