Welcome to PowaMaster

PowaMaster is a premier Power System Analysis tool for meshed electrical power system analysis and simulation, ideally suited for transmission and distribution systems. It focuses on balanced interconnected systems with full meshed network capability in a user friendly and efficient manner.

PowaMaster is fully integrated and not module based, which means that all the features work together as a coherent unit, allowing the user to perform many studies without leaving the main Graphical User Interface (GUI).

The range of functions and elements available in PowaMaster allow you to model complex networks and simulate a wide range of operating conditions.

The user simply draws the network using the mouse and the network elements provided. Calculations are performed when required and results are immediately displayed on the single line diagram.

API's

PowaMaster is an OLE/COM Automation Server, exposing some of the PowaMaster functionality to programs acting as OLE/COM Automation Controllers.

Any OLE/COM enabled application can link to PowaMaster to build networks on the fly and retrieve the results.

This gives the user the ability to develop any custom functionality and use any other programming interface to link to PowaMaster, such as AutoCAD, Microstation, GIS, Excel, C++, Visual Basic, Python, etc.
