NEPLAN-Simpow Integration STRI and BCP have agreed to integrate the Simpow dynamic and linear analysis modules in the NEPLAN planning and optimization software. NEPLAN users will now profit from one of the best dynamic analysis package, including transient stability, EMT simulation and linear analysis with most advanced dynamic models. Over 25 years development experiences are included in the Simpow package. This integration improves further the transmission system module in the NEPLAN power system analysis software. The new integrated versions of Simpow and NEPLAN will be available in July 2005. The combined package will be one of the most complete power system planning and optimization tool on the market. STRI and BCP will also collaborate within support, marketing and sales of their respective software. For further information, please contact STRI or BCP. Special features included in Simpow are: • EMT (instantaneous value mode) and RMS (fundamental frequency mode) simulation. • Enhanced Linear Analysis module with RMS and EMT models. • Many field proven dynamic models. • Robust numerical technique characterized by accuracy with variable and fixed time step. • To insure correct and fast results from the integration algorithm, the “backward differentiation method” is used for stiff integration variables and the “trapezoidal method” is used for non-stiff integration variables. • Calculation of Fast Fourier Transformation (FFT). • Enhanced dynamic synchronous machine models, including an advanced model for machine start-up simulations in EMT mode. • Enhanced dynamic asynchronous machine models. • Enhanced HVDC and the corresponding HVDC controller models. • Enhanced dynamic FACTS models. • Switching between fundamental frequency mode (RMS) and instantaneous value mode (EMT), just before an interesting point of time occurs. • Part of the network can be modeled in fundamental frequency mode (RMS) and on other part in instantaneous value mode (EMT). This feature is probably unique on the market. • The high level dynamic simulation language (DSL) allows not only to model user defined regulators but also primary components like synchronous machines, FACTS etc.

NEPLAN-Simpow Integration STRI and BCP have agreed to integrate the Simpow dynamic and linear analysis modules in the NEPLAN planning and optimization software.
NEPLAN users will now profit from one of the best dynamic analysis package, including transient stability, EMT simulation and linear analysis with most advanced dynamic models. Over 25 years development experiences are included in the Simpow package.
This integration improves further the transmission system module in the NEPLAN power system analysis software.
The new integrated versions of Simpow and NEPLAN will be available in July 2005.
The combined package will be one of the most complete power system planning and optimization tool on the market.
STRI and BCP will also collaborate within support, marketing and sales of their respective software. For further information, please contact STRI or BCP. Special features included in Simpow are:
• EMT (instantaneous value mode) and RMS (fundamental frequency mode) simulation.
• Enhanced Linear Analysis module with RMS and EMT models. • Many field proven dynamic models. • Robust numerical technique characterized by accuracy with variable and fixed
time step. • To insure correct and fast results from the integration algorithm, the “backward
differentiation method” is used for stiff integration variables and the “trapezoidal method” is used for non-stiff integration variables.
• Calculation of Fast Fourier Transformation (FFT). • Enhanced dynamic synchronous machine models, including an advanced
model for machine start-up simulations in EMT mode. • Enhanced dynamic asynchronous machine models. • Enhanced HVDC and the corresponding HVDC controller models. • Enhanced dynamic FACTS models. • Switching between fundamental frequency mode (RMS) and instantaneous
value mode (EMT), just before an interesting point of time occurs. • Part of the network can be modeled in fundamental frequency mode (RMS)
and on other part in instantaneous value mode (EMT). This feature is probably unique on the market.
• The high level dynamic simulation language (DSL) allows not only to model user defined regulators but also primary components like synchronous machines, FACTS etc.
