Simulation Options
Load-Flow solution
- The electrical network equations are solved using complex phasors. The active (source)
devices are only the Load-Flow devices (LF-devices). A load device is used to enter PQ
load constraint equations.
- Only single (fundamental) frequency solution is achievable in this version. The solution
frequency is specified by ‘Default Power Frequency’ and used in passive network lumped
model calculations.
- The same network used for transient simulations can be used in load-flow analysis. The
EMTP Load-Flow solution can work with multiphase and unbalanced networks.
- The control system devices are disconnected and not solved.
- This simulation option stops and creates a solution file (Load-Flow solution data file). The
solution file can be loaded for automatically initializing anyone of the following solution
methods.
Steady-state solution
- The electrical network equations are solved using complex numbers. This option can be
used in the stand-alone mode or for initializing the time-domain solution.
- A harmonic steady-state solution can be achieved.
- The control system devices are disconnected and not solved.
- Some nonlinear devices are linearized or disconnected. All devices have a specific
steady-state model
- The steady-state solution is performed if at least one power source device has a start time
(activation time) lower than 0.
Simulation Options (Con’t)
Time-domain solution
- The electrical network and control system equations are solved using a
numerical integration technique.
- All nonlinear devices are solved simultaneously with network equations. A
Newton method is used when nonlinear devices exist.
- The solution can optionally start from the steady-state solution for initializing
the network variables and achieving quick steady-state conditions in timedomain waveforms.
- The steady-state conditions provide the solution for the time-point t=0. The
user can also optionally manually initialize state-variables.
Frequency scan solution
- This option is separate from the two previous options. All source frequencies
are varied using the given frequency range and the network steady-state
solution is found at each frequency.
EMTPWorks features:
 Object-oriented design fully compatible with Microsoft Windows
 Powerful and intuitive interface for creating sophisticated Electrical
networks
 Drag and drop device selection approach with simple connectivity
methods
 Both devices and signals are objects with attributes. A drawing canvas
is given the ability to create objects and customized attributes
 Single-phase/three-phase or mixed diagrams are supported
 Advanced features for creating and maintaining very large to extremely
large networks
 Large number of subnetwork creation options including automatic
subnetwork creation and pin positioning. Unlimited subnetwork nesting
level
 Options for creating advanced subnetwork masks
 Multipage design methods
 Library maintenance and device updating methods
