Interactive graphics interface for power system network analysis

The evolution in user-machine interfaces for power system network analysis software is examined, and an interactive graphics approach is described. Batch and interactive processing are defined, and the drawbacks of text-based interactive interfaces are identified. The development of a user-machine interface for power system network analysis using interactive graphics is described. The conceptual model used to visualize the power system is the one-line diagram. The task of modifying the network and the task of editing the one-line diagram are combined into a single task. The use of command modes in the program was avoided by supporting the full range of commands at all times. From the user´s perspective, the program appears as a single entity rather than a collection of different modules.<>
