This is the official open source code repository for the production implementation of the NASPI PMU Registry. It is expected that implementations of this source code outside the official repository (http://www.naspi.net/)
will be used for security review, commerical product integration testing, internal registry proxy implementations and academic research.
About the PMU Registry
The North American Synchrophasor Initiative (NASPI) Phasor Measurement Unit (PMU) Registry is a
North American Electric Reliability Corporation (NERC) initiative to provide a common location for documenting the configuration of devices making phasor measurements on the North American electric power system.
The primary purpose of the PMU Registry is to provide a structure for mapping synchrophasor data from multiple substations and multiple utilities so that this data can be used as an integrated set of information with all parties knowing where and how the
phasor measurements are taken. As a
name server, one of the most important services of the PMU registry is provide attribute information about phasor measurements as based on a unique measurement key.
The PMU Registry does not contain
synchrophasor data. It is service that provides other computing systems such as Phasor Data Concentrators
metadata about devices that make synchrophasor measurements -- typically a dedicated PMU or a relay.
The types of metadata provided by the PMU Registry include device installation status, device make and model, device physical location, and the electrical location of the measurements made. The PMU Registry contains a unique key for every measurement. The
registry can also store additional measurement keys that are used within utilities or regions that are formatted to support specific applications, data packaging, or communications standards.
As a simple example, if Transmission Owner A installs a new PMU, Regional Entity B will be informed when the PMU goes into service and will dynamically be provided the same configuration information as is used by Transmission Owner A. The value of the PMU
Registry increases as additional Transmission Owners and Regional Entities are also made aware of this new phasor measurement information.
