Supervisory Control and Data Acquisition (SCADA)
SCADA refers to an
industrial control system monitoring power generation and other
industrial processes. SCADA systems provide communication to
multiple data protocols with all necessary conversions. SCADA
also provides data paths for meter information to the
generator's central control unit for closed-loop and
reverse-power control.
Data Processing Gateway (DPG)
The DPG is the required SCADA system for
Non-AGC generating facilities participating
in the ISO markets. It consists of an Areva
e-terra system that acts as the data hub for
intelligent electronic devices located in a
generating facility. The DPG is capable of
communicating with devices utilizing DNP
3.0, OPC, Modbus, or PI protocols. The DPG
in turn makes the facility's data available
to the ISO, the facility owner, and any
other approved user. Trimark currently
performs more DPG installations and
configurations in California than anyone
else. Our staff, in addition to being
skilled metering installers and inspectors,
has extensive, direct experience with the
ISO and its considerable requirements for
documentation of metering and DPG
installations. Additionally, Trimark offers
a range of other communications and metering
products and services to fit the needs of
any generating facility.
