1. INTRODUCTION
ISO’s and Reliability Coordinators share reliability data for the responsible management of the bulk power system. As Phasor Measurement Units (PMU’s) and
Phasor Data Concentrators (PDC’s) are deployed across this system, the NERC Data Exchange Working Group (DEWG) has recommended guidelines for defining
this data. The first version of the PMU Data Definition File (PMU DDF) template was accepted at the April 19, 2012 DEWG meeting in Albany, NY.
2. PMU DDF FILENAME
The PMU DDF filename is to take the following format: <NERCNETID>_PMU_YYYYMMDD.XLS. For NYISO, the published file would be
NYISO_PMU_20120501.XLS.
3. PMU Data Validator
The PMU Data Validator is a utility to check individual files against the rules put forth in the PMU DDF template. Many of the test requirements were outlined at
NERC Data Exchange Working Group (DEWG) meetings.
4. DATABASE LAYOUT
When viewing the queries, similar tests are grouped together with a "QA" prefix. For example, QA0600 grouping check valid field entries for several fields. The
next identifier in the query name is simply to help sort the order in which the queries should be executed. Finally, the query name will have a short description
of the test. Any tables created from queries will have the same name as the query except for the "tbl" prefix. Tables with "LOOKUP" prefixes contain valid field
entries. Queries with "QRY_LIST"prefixes simply query the LOOKUP table and sort valid field names used in combo boxes on the forms.
5. IMPORTING YOUR REGISTRY
You may import your registry on your own or use one of the import buttons on the Validator Display. There is one button to import a text file and another to
import an MS Excel file. Regardless, your registry must be imported into a table called REGISTRY_TARGET with all the appropriate field names listed below.
During import, please be sure an ID field is created which is type AUTONUMBER. This will assign a primary key to each record in your registry and is a key
element throughout the validation process. A copy of this table is created in PREREQ_REGISTRY TARGET and several validation tests are performed on
PREREQ_REGISTRY_TARGET.

The ID field should be added during import, as type autonumber, to be used as the primary key. Some fields should only contain specific values as displayed
below.
7. PREPARING FOR VALIDATION
After importing your registry into the REGISTRY_TARGET table with the appropriate field names, you are ready to validate it. The PMU Registry Validator
performs various tests against your data and sends the results to the screen. The results can be found in the REGISTRY_OUTPUT table.
8. FIELD VALUES
Some fields must contain specific values. This section displays the valid data entries for these fields:

Document History
Apr 19, 2012 NERC DEWG meeting. First version of PMU registry requirements approved.
Jan 16, 2014 NERC DEWG meeting. DevType = LOAD and COMP (compensator) added. DataType FREQ_DFREQ was changed to FREQ. It is
assumed that frequency deviation always accompanies this signal. MeasurementType = ANGLE was removed. It is assumed that angle
always accompanies the magnitude.
Apr 10, 2014 NERC DEWG meeting. MeasurementType=FREQUENCY added.
