IEC 61850-9-2LE Sample Value Stack (PIS-11)

The PIS-11 IEC 61850-9-2 LE Sampled Value Publisher is a hardware platform specific sampled value publisher application for the Smart Grid IoT Platform using the dual core Intel ARM/FGPA Cyclone V SoC.

This Smart Grid IoT Platform provides eight high precision analogue inputs. The A/D converter is directly controlled by the FPGA producing the sampling rate required for the SV publisher, which is implemented in one ARM core.

The Sampled Values are published at a rate of 4000 frames per second for a grid frequency of 50Hz and 4800 frames per second for 60 Hz.

An eight channel Voltage Transformer / Current Transformer (VT/CT) interface module is also available from SystemCORP Energy allowing a direct connection of the Smart Grid IoT Platform to 110 Volt VTs and 5 Ampere CTs.

 

Integration

SystemCORP Energy offers system implementation engineering services for software and hardware development projects using the Smart Grid IoT Platform with various real-time operating systems and hardware interface requirements.
