ADVANCED COMPUTER ANALYSIS OF
POWER SYSTEM CONTROL AND POWER ELECTRONICS TRANSIENTS
EMTDC/PSCAD (INTRODUCTION)
EMTDC (ElectroMagnetic Transients for HVDC).
• Developed in 1975 by Manitoba Hydro to study the
Nelson River HVDC power system
• Used extensively for many types of power simulation studies,
• Used in both Unix and PC systems
• A more user friendly version of EMTP program
PSCAD (Power Systems Computer Aided Design)
• A graphical User Interface to EMTDC
• PSCAD V1 in 1988 on Apollo workstations,
• PSCAD V2 in 1995 on Unix systems
• PSCAD V3 in 1999 for PC Windows platforms. (not available in Unix).
EMTDC/PSCAD (UNIX VERSION)
Version 2, Unix
• 6 Workstation computers which has license of EMTDC/PSCAD at VT
Coconut, Yew, Ash, Sycamore, Pear, Peach
• Your login file “.cshrc” should be modified to include the
path lines.
• These computers can be accessed by other workstation
computers by telneting, or by PCs using Xwindows software.
TELNET
Assume you are using X machine which does not have the EMTDC license and want to telnet to Y machine
X:/home/ loginname > xhost “Y”
X:/home/ loginname > telnet “Y”
X:/home/ loginname > setenv DISPLAY “X”:0.0
Y:/home/ loginname > PSCAD &
XWINDOWS
There is a two hour usage limit.
PSCAD/DRAFT MODULE
• Collection of components or circuits can be dragged from library palette into drawing canvas to assembly a circuit.
Network Components:
RLC components, Transformers with saturation, Frequency dependent
transmission lines cables, synchronous machines, induction motors with exciter governor and turbine models, faults, breakers, surge arresters, current voltage sources, multiple harmonic injectors
Power Electronics Components: Thyristors, diodes, GTOs, HVDC valve group, SVS and FACTS devices
Control Blocks: Derivative, delay, differential lag, integrator, limit, complex pole, real pole, lead lag, filter, amplifier, switch and Boolen functions
Meters: Voltmeters, ammetters, real reactive power meters, peak detectors, phase angle and frequency meters
