General > Vision: introduction

Vision is a high-grade tool for analysis of electricity networks. Vision can be used to carry out load flow calculations, short-circuit calculations and fault analyses. Also the proper working of your over current protection can be simulated and selectivity analysis can be carried out. Vision can be used to carry for planning, design and operation of electrical transmission, distribution and industrial networks.

Vision compromises of the software and a PC or network key.

Introduction

Vision is designed for both frequent and occasional users. To ensure a high degree of familiarity, the functionalities offered by Windows were used as much as possible in the development. All general functions associated with this are therefore not described in this introduction.

However, Vision has a number of specific features and functions which one needs to know to be able to work with Vision. This introduction describes the installation procedure as well as the key features and functions.

Installation

Vision can be installed on a computer as follows:

•download the latest version of Vision from www.phasetophase.com

•install Vision Network analysis

•For the installation of the network key: see Hardware key. In this case, nothing needs to be installed at the client.

•For the PC key: plug the PC-key into the computer's USB port. For a SuperPro key: install the driver. See: Hardware key.

Startup

Click on the Start button and choose Vision Network analysis.

When using the network key, activate the network key option in the Application menu | Options | Network Key.

Network representation

The network is represented as a single-line diagram comprising of the nodes (busbar systems), branches (for example cables or transformers) and elements (for example generators or loads).

Selections

Many actions within the editor only relate to the selected components. Selected components are shown in the selection colour (default: white). A specific selection of components can be saved (to create: Insert | Miscellaneous | Selection; to select: Start | Select | Object, Selection).

Edit mode and Result mode

The network editor has an Edit mode and a Result mode. The presentation of data and results differs between the two modes. The Result mode is only available after a calculation has been carried out. With View | Mode | Edit and View | Mode | Result one can switch between the two modes.

Views and Reports

Definition of Views enables the user to determine the presentation of information for themselves in the single-line diagram (to create/change: Tools | Definitions | Views; to select: View | View | <View>).

Reports enable the user to compile custom reports (to create/change: Tools | Definitions | Reports; to print: Application menu | Print | Report).

Type

Addition and modification of network components is supported by component database. This database contains type data for busbar systems, cables, transformers, reactance coils, generators, motors, circuit breakers and protection relays. The component database is an Excel-file with the default name: Types.xlsx.

Options

Vision can be configured by the user via Application menu | Options. Through these options the settings for both the editor and the calculations can be altered.

Help

Extensive support is provided via the help function, which is called with F1. The help function contains a description of all the editor functions, components and calculations.

Menu and mouse control

Most of the control actions are performed through the use of the ribbon menu and the mouse. The most important functions are explained in: Menu and mouse control.
