Category: Power Monitoring
Apart from building smart energy metering systems, SP Energosfera can be also used for creating full-scale power quality monitoring and control systems (PQMCS).
Power Quality Monitoring System Energosfera ensures automatic acquisition and long-term storage in the data base of various power quality indicators (PQI): frequency and voltage deviations, voltage asymmetry coefficients in a 3‑phase network, harmonics coefficients of current and voltage, short- and long-term flickers, parameters of instantaneous voltage change, etc. Acquired information is accumulated in the data base as current values, averaged values in common intervals as well as results of PQI statistical analysis for long periods (days or weeks).
Power quality control can be implemented as an additional subsystem within Smart Metering System Energosfera or as an individual, standalone Power Quality Monitoring System. A typical structure of Power Quality Monitoring System Energosfera® is shown in Fig. 2.
