Features:

Window Management Version 3.0.6 : Feature Note-121 08/06/1999

It is no longer possible to move a network diagram window over the main ERACS application window. Also, as the main ERACS application window is moved the network diagram windows, results listing windows and graph windows are moved relative to it.


Protection Links Version 3.0.6 : Feature Note-120 08/06/1999

A table listing the switches controlled by each operational relay is written to the Protection Setting comma separated variable (CSV) file.


Loadflow Version 3.0.6 : Feature Note-119 08/06/1999

Following requests from users we have extended the range of shunts to include Constant Current shunts and a new class of Special Shunt. The Constant Current Shunts can be specified in either Amperes or kilo-Amperes. They maintain constant current down to 0.5 p.u. in Loadflow. Below 0.5 p.u. voltage they become fixed impedance where the impedance is 'frozen' at that value which would give target current at 0.5 p.u. voltage. The class of Special Shunt was created for a specific customer and instances of this class cannot be created by other users. However, we have designed the software to be extensible in this area and would be interested in your views as to whether or not other shunt characteristics would be of interest to you. Whilst carrying out this work we also improved the way PQ shunts are handled. They now maintain constant current down to 0.8 p.u. in Loadflow. Below 0.8 p.u. voltage they become fixed impedance where the impedance is 'frozen' at that value which would give target current at 0.8 p.u. voltage. As before, all shunts are fixed at their loadflow impedance values for the other calculation engines.
