The DSAToolsTM
provides a complete toolset for power system planning and
operational studies. In addition to rich
modeling capabilities and leading-edge computational methods,
the software is highly automated and can provide
engineers with significant productivity improvements.
PSATPowerFlow & Short Circuit Assessment Tool
PSATTM
is a full-featured graphical powerflow program that includes
table-driven data manipulation and a flexible one-line
diagram
capability. It can be used for stand-alone powerflow analysis or
for
data exchange with other DSAToolsTM
products.
Applications:
Creating and modifying powerflow models Contingency assessment
including overload and voltage studies Producing diagrams for
output reports Setting up initial conditions for other DSAToolsTM
applications
VSATVoltage Security Assessment Tool
VSATTM is a highly automated steady-state analysis tool designed
for comprehensive voltage security assessment.
VSAT includes flexible specification of voltage security
criteria and is
designed to handle a large number of contingencies, power
transfers
and scenarios.
Applications:
Reactive power planning studies Operational planning studies
(security limit assessment) On-line voltage security assessment Any
analysis involving assessment of thermal overloads
determination of voltage security limits, evaluation of
required voltage stability margins, transfer limits (ATC
&TTC)
TSATTransient Security Assessment Tool
TSATTM
is a leading-edge full time-domain simulation tool designed for
comprehensive assessment of dynamic
behavior of complex power systems. TSAT includes a rich model
library, state-of-the-art solvers, and a highly
intuitive user interface. Like VSAT and SSAT, TSAT can
automatically find security limits under specified
contingencies and transfer conditions.
Applications:
Studies involving rotor angle, voltage, or frequency stability
Transmission system design and operating studies including
stability limit assessments
IPP integration studies Design and setpoint determination of
special protection
systems
Control tuning and protection coordination

SSATSmall Signal Analysis Tool
SSATTM
is an eigenvalue-based software tool designed for analysis of
small signal stability of large complex power
systems. It includes a wide number of analysis functions and
productivity
tools, making it ideal for investigating oscillatory behavior,
and for designing
and tuning controls to improve system damping.
Applications:
Studies of low-frequency inter-area oscillations Analysis of
local or inter-machine modes of oscillations Design and tuning of
controls Investigation of the sensitivity of system parameters on
modes of
oscillation
Contingencies screening to meet damping requirement
Determination of power transfer limit to meet damping
requirement
CDTControl Design Toolbox
CDTTM
is a specialized software tool for tuning power system
stabilizers. CDT
works with Matlab and SSAT to provide advanced tuning and bench
marking
capabilities and is available as a stand-alone tool or as an
add-on module to
SSAT
On-Line Application of DSATools
Security Assessment in Near Real-Time
The DSAToolsTM
is designed to provide on-line security assessment when used in
real-time
sequence of the control centers energy management system (EMS).
The software works
with a solved powerflow provided by the state-estimator and
communicates with the EMS
via dedicated data exchange protocol. Powertechs
DSAManagerTM
controls all computations
which are conducted on a dedicated cluster of computers and, if
necessary, distributed
processing is used to meet performance requirements. Results may
be passed back to the
EMS console or are accessible locally or remotely.
WSAT Wind Security Assessment Tool
Powertechs on-line DSA technology is used with the Wind Security
Assessment Tools (WSAT), in joint development
with the Irish national grid company EirGrid. WSAT is now
operational at the National Control Centre (NCC) of EirGrid.
