Operation principle

Upon receiving an analog signal at its input, IEC61850 generic communication I/O
functions (MVGGIO) will give the instantaneous value of the signal and the range,
as output values. In the same time, it will send over IEC 61850-8-1 the value, to
other IEC 61850 clients in the substation.

Measurements

Functionality

Measurement functions is used for power system measurement, supervision and
reporting to the local HMI, monitoring tool within PCM600 or to station level for
example, via IEC 61850. The possibility to continuously monitor measured values
of active power, reactive power, currents, voltages, frequency, power factor etc. is
vital for efficient production, transmission and distribution of electrical energy. It
provides to the system operator fast and easy overview of the present status of the
power system. Additionally, it can be used during testing and commissioning of
protection and control IEDs in order to verify proper operation and connection of
