Technical Annex: Monitoring System

TITLE VI. PHASOR MEASUREMENT MODULE

The phasor measurement unit or PMU will form the basis of the phasor measurement system. Thus, the PMU will acquire the data from the secondary windings of the voltage and current transformers synchronously using GPS, process them, and obtain the voltage and current phasors. These phasors will then be sent to the data concentrator.

Every phasor measurement system will require at least one centralized concentrator equipment (PDC) whose functions are the reception, storage and processing of the measurements that have been obtained from the PMUs.

All installations over 200kV, and those with lower voltages where the Coordinator justifiably requires it, must have the technical feasibility of installing a phasor measurement unit and have installed communications capacity for integration into the PDC concentrator equipment, with the required standard.

The phase measurement equipment and associated communication systems must be able to operate in real time at the rate of sending messages defined in IEEE C37.118 from the PMUs, for which a precision of the synchronization system is required in accordance with that standard (+/- 1μs in less than 16 network hops) and an Ethernet network based on the IEEE 1588 v2 standard (Power Profile).
