Wide Area Monitoring System (WAMS) Application in Smart Grids

Digital microprocessor devices are widely used in modern dispatching. The introduction of wide area measurement systems (WAMS) is one of the priorities of the technological development of power systems globally. WAMS use a well-studied method of measuring phasor (phase vector) data in various geographically remote sections of power grid lines. With appropriate software processing, the data coming from the phasor measurement units (PMUs) allows: providing dispatch centers with data on the overall system stability; increasing the reliability of maintaining the power system operation state; obtaining cost savings by reducing or removing restrictions on power flow capacities in critical sections in real-time; maximizing the utilization of most efficient, competitive power plants, reducing the volume of consumer restrictions.
