WAMS

ENIP-2 PMU performs phasor current and voltage measurements и calculates grid parameters. 

ENMV-3 measures direct voltage and current in generator excitation circuits.

ES-PDC aggregates and transmits data via IEEE C37.118.2, records cyclic and emergency archives of a configurable depth. The ES-PDC stores measurements and fault events in archives of adjustable depth. The ES-PDC functionality also includes online analysis of measurements and detection of low-frequency oscillations (LFO). The calculation results can be transmitted to higher-level WAMS and used to assess the involvement of the monitored object in the LFO process in the power system, as well as to identify LFO sources.

ENCS-3m transmits data to the higher level via IEC 60870-5-104.

ENMI-6 diagnostic panel controls states of system elements.

Time is synchronized by ENCS-2.
