ETAP PowerStation is a fully graphical electrical transient analyzer program that can run under the Microsoft® Windows® 98, NT 4.0, 2000, Me, and XP environments. The Windows NT 4.0 and 2000 platforms provide the highest performance level for demanding applications, such as large network analysis requiring intensive computation and online monitoring and control applications.
Windows NT 4.0 and 2000 also provide the highest levels of reliability, protection, and security of critical applications. Large PowerStation projects (approximately 500 buses and larger) should be built and maintained via Windows NT 4.0 or 2000. The Windows 98 and Me platforms provide excellent performance for analysis of small and medium size systems (a few hundred buses) and support a variety of other popular applications
PowerStation allows you to work directly with graphical one-line diagrams and underground cable raceway systems. The program has been designed according to three key concepts:
Virtual Reality Operation
The program operation resembles real electrical system operation as closely as possible. For example, when you open or close a circuit breaker, place an element out of service, or change the operating status of motors, the de-energized elements and sub-systems are indicated on the one-line diagram in gray. PowerStation incorporates new concepts for determining protective device coordination directly from the one-line diagram.
Total Integration of Data
PowerStation combines the electrical, logical, mechanical, and physical attributes of system elements in the same database. For example, a cable not only contains data representing its electrical properties and physical dimensions, but also information indicating the raceways through which it is routed. Thus, the data for a single cable can be used for load flow or short-circuit analyses (which require electrical parameters and connections) as well as cable ampacity derating calculations (which require physical routing data). This integration of the data provides consistency throughout the system and eliminates multiple data entry for the same element.
Simplicity in Data Entry
PowerStation keeps track of the detailed data for each electrical apparatus. Data editors can speed up the data entry process by requiring the minimum data for a particular study. In order to achieve this, we have structured the property editors in the most logical manner for entering data for different types of analysis or design.
PowerStation’s one-line diagram supports a number of features to assist you in constructing networks of varying complexities. For example, each element can individually have varying orientations, sizes, and display symbols (IEC or ANSI). The one-line diagram also allows you to place multiple protective devices between a circuit branch and a bus.
PowerStation provides you with a variety of options for presenting or viewing your electrical system. These views are called presentations. The location, size, orientation, and symbol of each element can be different in each presentation. Additionally, protective devices and relays can be displayed (visible) or hidden (invisible) for any particular presentation. For example, one presentation can be a relay view where all protective devices are displayed. Another presentation may show a one-line diagram with some circuit breakers shown and the rest hidden (a layout best suited for load flow results).
Among PowerStation’s most powerful features are the composite network and motor elements. Composite elements allow you to graphically nest network elements within themselves to an arbitrary depth. For example, a composite network can contain other composite networks, providing the capability to construct complex electrical networks while still maintaining a clean, uncluttered diagram that displays what you want to emphasize - yet the next level of system detail is within easy reach of your mouse. The power is at your fingertips.
We consider PowerStation to be the foremost-integrated database for electrical systems, allowing you to have multiple presentations of a system for different analysis or design purposes.
