Abstract
This paper presents the design, implementation and validation of a
M-Class PMU on a general purpose embedded controller, concurrently used
for inverter and grid control tasks, deployed over a unified real-time
control environment. The rising number of embedded controllers in active
distribution grid opens an opportunity for shared computation and
instrumentation resources. Unified real-time control environments can
efficiently coordinate multiple embedded controllers, IOs and models
from different toolchain. The PMU in this paper, is implemented within
the NI Veristand real-time control environment at CoSES laboratory in TU
Munich. It uses the existing instrumentation and controller setup for
inverter and prosumer control in an active distribution grid laboratory.
The PMU passes all Mclass device accuracy tests set by the IEC/IEEE
60255-118-1 standard. The output is compliant to the IEEE-SA C37.118.2
messaging standard and connected to an open source PDC software. The
proposed solution demonstrates the possibility of merging different grid
control and operation functionalities within the unified Veristand RT
control environment.
