ETMS (Electromagnetic Transient Modeling and Simulation) 

Shouler’s power system analysis software ETMS is an ideal tool for analyzing and researching modern large-scale interconnected power systems. From the most basic analysis of power flow short circuits, grid voltage levels, calculation of component thermal overload, to transient stability, short-term dynamic stability, small disturbance stability, and voltage stability analysis of complex power systems, to the design, modulation, and other aspects of various power system controllers and stability control devices, ETMS can meet the requirements of modern power grid planning, operation, and control.
 
Advanced simulation computing technology and powerful model solving capabilities endow ETMS with the ability to analyze and study interconnected power grids of any scale in the world today. The powerful user graphical interface and calculation result analysis and processing functions make the operation of ETMS and the production of research reports easier and more convenient.
 

The ETMS power system dynamic security comprehensive analysis software currently includes the following functional modules:

Trend and Short Circuit Analysis Program: PSA (Powerflow&Short circuit Analysis)
Voltage Security Assessment (VSA)
Transient Security Assessment (TSA)
Small Signal Analysis (SSA) is a small signal stability analysis program
User defined model graphic editor: UDM Editor
Design and tuning of power system stabilizer PSS: CDT
Online dynamic security analysis platform: DSA Manager
