Mission

The mission of the NASPI Distribution Task Team (DisTT) is to advance the uses and value of synchronized measurements on or connected to distribution systems of all voltage levels. This group shares information in support of effective research, development and deployment of distribution phasor (PMUs), waveform (WMUs) and related measurement devices/units. We aim to grow a community to solve technical and other challenges specific to synchronized measurement technology and its applications in distribution system operation, planning and analysis.

Point-on-wave data collected on the 20 kV network of EPFL-campus. Visit GitHub to learn more.

DRAFT NASPI DisTT Use Case: DG-Load Disaggregation

Release Date
ERICA Number
NASPI-2017-TR-011
Document Subject Area
DisTT Use Case
Description
Use Case Disaggregation of net metered distributed generation (DG) from customer load uses high-precision measurements on the utility side of the meter to estimate the actual generation and amount of load offset behind the meter. Background When the distribution utility lacks access to separate load...

DRAFT NASPI DisTT Use Case: Fault Location

Release Date
ERICA Number
NASPI-2017-TR-010
Document Subject Area
DisTT Use Case
Description
Use Case Synchronized measurements at multiple locations throughout a distribution system during a fault can aid in the location of the fault and expedite service restoration. Background The vast majority of faults originate in distribution systems. The traditional means of locating a fault on a...

NASPI DisTT Use Case: Synchrophasor Assisted Microgrid Automation

Release Date
ERICA Number
NASPI-2016-TR-013
Document Subject Area
DisTT Use Case
Description
Use Case Conventional remote terminal unit (RTU) based automation approaches suffer from slow measurement update and lack of time-stamp values for precise comparison of state parameters at different locations . A time-synchronized control approach is more favorable for protection event analysis...
