CONTROL INTERFACES
A Control Interface is just as its name describes: A user interface object, which allows manual adjustment of an EMTDC data input variable by the user. A Control Interface must first be linked with one of the I/O Devices available in the Master Library (i.e. Variable Real/Integer Input Slider, Two State Switch, Rotary Switch (Dial), and Push Button). The Control Interface will then control the output of the linked control component. For example, the following image shows a Slider component linked to a control interface in a control panel.
OVERLAY GRAPHS
Here is an example of Overlay Advanced Graph. The Graph frame contains several interactive features that will allow users to easily analyze output data. The graph frame employs auto scaling with Smart Axis developed by Z Systems. The frames are performance optimized to manage the massive amounts of data that EMTDC generates as an electro-magnetics transient program. The time axis allows scrolling in time and also employs a dynamic aperture to give a window of scope desired in the view. Conventional zoom and cross hairs are also available, and a set of markers to give the differential between two points is readily accessible. Users can customize the look and feel of the plots with dialog controls, and data from the plots can be copied to the clipboard to be analyzed in any other 3rd party data analysis program.
XY PLOTS
PSCAD has XY plot feature that is useful for some types of data analysis, particularly impedance trajectory plots for the study of relay protection systems.
The XY Plot is a special type of Runtime object, which is composed of both a Graph Frame and a single, specialized Graph window for the purpose of plotting one Curve versus another. An XY Plot can accommodate multiple Curves on each of the X and Y-axes, and includes Dynamic Zoom and Polar Grid features.
