values, such as active power, reactive power and power factor, etc., to provide overall
monitoring information. All these quantities can be sent to a SCADA or a Station Gateway
through a switcher.
Time Synchronization
The module provides an interface to receive time synchronized signals from external clock
synchronization source. This module also has a local crystal oscillator to maintain the internal
time accuracy when outside synchronization source breaks down. The synchronization mode
includes PPS (pulse per second) mode and IRIG-B mode. Basing on the outside timing
message (from SCADA or Station Gateway) or the PPS signal or the IRIG-B signal, this
module can adjust its time within the timing accuracy.
The frame of the CPU module terminal is described as below. The detailed configuration is up
to the project requirements.
