ERACS Version 3.1.0 - Released: 03/11/2000


Guests may only view features, to also view fixes made to this version please login.

Features:

Network Dimensions Version 3.1.0 : Feature Note-87 03/11/2000

The busbar and bus section limits of the extended version (previously 1000 and 350) have been increased to 1500 and 850 respectively.


Network Diagram Window Version 3.1.0 : Feature Note-86 03/11/2000

When an element hotspot has been encountered the mouse cursor changes from a cross-hair to an arrow-head. Thereby providing a clear indication that a hotspot has been found and an operation is available via the mouse right button popup menu.


Zoom Window Version 3.1.0 : Feature Note-85 03/11/2000

The zoom window includes a rectangular box that indicates the active area, that is, the area of the network that is currently accessible in the network diagram window. This box is now shown in colour and when the mouse cursor passes over the box, the cursor changes from a cross-hair to an arrow-head. To change the colour used to fill the box, click the mouse right button whilst the mouse is over the box and select 'Change Colour...'. This will reveal the standard Windows colour dialog enabling you to select the colour.


Snap On Grid Version 3.1.0 : Feature Note-84 03/11/2000

A snap on grid has been included. This feature may be enabled by selecting Grid from the View menu. This feature is primarily of use when creating new networks. It may however, be used on existing diagrams to retrospectively align elements to the grid. But this may only be achieved by moving individual elements.


View Menu Version 3.1.0 : Feature Note-83 03/11/2000

Two new options called 'Busbar Identifiers' and 'Protection Device Identifiers' have been added to the View menu. These enable you to easily show or hide all busbar or protection device identifiers.


Transient Stability Version 3.1.0 : Feature Note-82 03/11/2000

An additional class of load torque variation has been included for induction generator events. You are now able to select one of the multi-point load profiles entered into the library as a Time Variant Function.


Summary Results Block Version 3.1.0 : Feature Note-81 03/11/2000

It is now possible to start the move operation for the summary results box by clicking the mouse right button whilst the mouse is over the results block and selecting Move from a popup menu.


Library Version 3.1.0 : Feature Note-80 03/11/2000

A new model has been included in the library, which enables time variant functions to be represented by a multi-point curve. In this first instance they can only be used to represent load torque variation profiles for induction generators. However, it is envisaged that this facility will be extended to include time variant electrical loads.


Calculators Version 3.1.0 : Feature Note-79 03/11/2000

The following calculators have been added to ERACS and can be accessed via the Calculations option of the Tools menu: - Impedance converter: This calculator enables you to convert ohms to per unit and vice versa. - Inertia Constant Calculator: This utility will calculate inertia constant, H. - Transformer Impedance Calculator: Given the inter-winding impedances of a 3 winding transformer and the ratings of each winding, this utility will calculate the individual impedances of each winding. These values may then be entered into the ERACS library.


Block Selection Version 3.1.0 : Feature Note-78 03/11/2000

It is now possible to block select an area of the network diagram following a Protection calculation and either copy the selection as a bitmap, or, print the selection.
