The document discusses several types of electrical power system software used for modeling and analysis, including Matlab, NEPLAN, Easy Power, SPARD, Powerworld, and DigSILENT. It provides brief descriptions of the capabilities and uses of each program. For example, Matlab allows simple simulations but lacks detailed electrical modeling, while NEPLAN offers web-based analysis of power, water, gas and district heating networks. The document concludes that the choice of software depends on the required analysis and system complexity.

3. Introduction
• Due to the advancement of technologies in the
field of power systems, the analysis of these
becomes increasingly complex and therefore it
requires the use of computational tools that help
us with this wasteful work.

4. Electrical Power System software
In the United States alone, power systems engineering is a $100
billion industry. The goal of these systems is to ensure that
potential electrical power problems are "engineered-out" of the
design, prior to a facility being constructed.

5. Electrical Power System software
There are a wide range of electrical engineering tests that can be performed on a power systems CAD
model. These include tests for:
• Short Circuit Analysis
• AC and DC Arc Flash
• Protective Device Coordination
• Power Flow
• Cable Pulling
• Power System Reliability
• Electromagnetic Transient Analysis
• Cable Ampacity
• Induction Motor Parameter Estimation
• Transmission Line Parameters
• Power System Optimization
• Advanced Substation Grounding Grid Design
• Advanced Motor Starting
• Voltage Stability and Contingency Analysis

6. What is the difference between them?

7. Matlab
• It is useful in order to do simple
simulations or without big
complexity.
• Direct access to MATLAB and
simulink environment.
• Model calibration can be added,
which enables parameter
estimation.

8. Matlab
• It has problems with specific
analysis
• Only mathematical modeling.
• Model overview is not as good as in
programs that enable electrical
modeling.
• Many models only include part of
the behavior of actual components

9. NEPLAN
• Neplan offers the first web-based power
system engineering software.
• It Counts with analysis of water, gas and
district heating networks.
• It has compatibility with a lot of
programming languages such as C++ or
with Matlab.
• No other tool on the market provides so
many analysis functions for transmission,
distribution, industrial, marine and
offshore networks.

10. Easy Power
• EasyPower is used by some
branches of the government
• It is easy to use because the
graphical interface is similar with
other electrical softwares
• You can add or modify any
library of the program in
order to enhance it and add
new devices and features
• It is compatible with other
programs like Autocad and
you can import or export
files in .dwg

11. SPARD
• Turnkey systems integrating SPARD
modules with SCADA and
commercial information systems
CIS, ERP and Hardware
configurations and supply.
• In our country it counts with
courses, training and customer
support includes IVR (Interactive
Voice Response).
• SPARD counts with mobile
solutions to run on computers,
smartphones or tablets.
• It has a Geographic Information
System (GIS) specially designed
for electrical networks. It
enables the creation of grid
elements geographically.

12. PowerWorld
• Powerworld accesses to
power system information and
analysis in a user-friendly
format
• Transmission atlas is a library
where you can see the
transmission system in north
america
• Powerworld offers generator
cost models allow to change the
price of the generation and get
tendencies of locational
marginal price
• To visualize real-time conditions
in the control room and
remotely.

13. DigSILENT
• DigSILENT is simple to
use and run simulations
i.e with load flow anylisis.
• It offers an Techno-
Economic evaluation of
grid expansion strategies.
• Provides a reliable central protection
settings database and management
system for the complete power system
substation data.
• DIgSILENT Grid Code v1.0, in
response to the need to verify if a
generator is compliant with local
Grid Code requirements on the
basis of unit tests executed.

14. Conclusions
• In recent years have been a big development of
software and they count nowadays with a great
industry.
• In the market exist a wide range of electrical power
system software each one of them with different
features and performance.
• The choice of any of them depends on you and the
requirement of the analysis and the complexity of
this.
