VSC Fault Protection

VSC Fault Protection The objective is to design and test a power system protection scheme that combines voltage and possible measurements from different locations in or near a wind farm to locate faults. A brand new method to detect the fault before it occures.

Project Statement
The objective is to design and test a power system protection scheme that combines voltage and possible measurements from different locations in or near a wind farm to locate faults. A brand new method to detect the fault before it occures.

Project Learning
Some of the shelf technologies that we will use are the following:
 * Real Time Digital Simulator (RTDS) -- The Real Time Digital Simulator (RTDS) is a special purpose computer that does time domain simulation solving the differential equations for a power system at discrete instants in time, 50 microseconds apart, and doing analog or digital I/O to external protection and control devices in real time. Such that the external devices don't know they are talking to a simulation instead of a real system.
 * RSCAD -- A graphical interface intended to be used in conjunction with RTDS.
 * PSCAD -- A non-real time graphical interface program that is the forerunner to RSCAD.
