Two phase measurement unit

[muscles05]

So i was wondering if somebody can point me in the right direction of how to get started with building a two PMU with labview that do the following

Design and Build Two Phase Measurement Units (PMUs)​

Monitors the voltage waveform of single phase residential utility circuit​

PMUs are GPS Synchronized ​

Each PMU displays Voltage, Angle, and Frequency on a LCD display​

LabView Interface must be designed and implemented with the purpose of gathering, displaying, and inserting the PMU data into MySQL​

Real-Time data from the PMU must be stored in a MySQL database to provide remote access​

Determine and display the power flow direction using a second LabView program

I also have a mydaq device just wondering how that come into play with​

What sort of LabVIEW Experience do you have?  What other LabVIEW projects (and types of Projects) have you successfully completed?  Are you a complete beginner, someone with CLAD experience, someone with CLD experience?

I've never programmed in Labview so just barely understanding the language but this part of a project I just want more Info on it

That set of requirements sounds like a near-professional grade instrument which could cost thousands of dollars. It als oo has at least one inconsistency: The first line refers to two phase PMUs while the next line refers to the voltage of single phase circuits. Design of PMUs is an active area of research.

Does it require the design of (quantity = 2) single-phase PMUs or (quantity = 1) two-phase PMU?

Measuring voltage but ignoring current seems somewhat limiting. 

What will be used as the timing reference for phase measurements? Is one unit to be the master and the other(s) slaves or will it use some other method?

Do the two PMUs (if there are two) share one computer and program or are the computers separate? Where is the MySQL database hosted? On the same computer or a separate one? How do the PMU and database communicate?

How do you expect to get power flow direction without measuring current?

What kinds of transducers and protective equipment will you be using to isolate the computer from the power line?

What are the accuracy requirements?

What kind of DAQ equipment will be used? What sampling rates will be used? How often do the displays and database values need to be updated?

It sounds like you need to start with basic understanding of the electrical issues involved before moving to the LabVIEW program.
