Motor Starting Analysis Software

Intuitive   Increases Productivity   Modeling Flexibility ETAP Motor Starting Analysis software enables system planners and engineers to calculate motor acceleration time and analyze the impact of motor starting for various conditions on electrical power systems. With the Motor Starting software module, you can

• Examine effects and find solutions for load impact & voltage flicker 
• Coordinate the starting sequence of multiple large motors 
• Evaluate the performance of an entire feeder under the stress of starting motors
• Find the worst-case impacts of starting motors anywhere in your system

Motor Starting Software Key Features

Perform Dynamic & Static Analysis

The ETAP motor starting software module provides dynamic analyses explicitly designed to study the effects of starting motors within your system.

Flexible Sequence of Events

The motor starting software is fully capable of starting individual motors or transitioning an entire electrical power system to another state.

Create Detailed Motor Models

Analyses take advantage of a detailed motor model, including torque characteristics, fully considered by load-flow calculations. Sequence-start a series of machines using static or dynamic models.

Optimize Motor Starting using Starters

Evaluate and choose appropriate motor staters like VFD and softstarters to minimize network impact.

Considers Network Dynamics

Include switching actions of reactive power compensation devices like Regulators, Substation Transformer Load Tap Changers, Switched Capacitor Banks, etc.

Advanced Plotting, Analyzers & Scripting

Advanced plotting and time varying graphical display enable engineers to quickly evaluate results and make decisions.
