Feature Summary

DINIS is an integrated data capture and electrical network analysis workstation package which operates either as a stand alone system integrated to other applications. DINIS allows control of network diagrams and associated plant data by including facilities for distributing copies of network areas (free polygon extraction), unlimited personal file copies for engineering planning needs, "freezing" of authorised extensions and other changes, and powerful file merge facilities through a visual compare and update routine with full automatic data checking and visual display.

Facilities for Engineers

Automatic network topology and data build from basic mapping
Comprehensive network storage, display and update facilities
Data exchange with external databases
System modelling display, combined or separate
Interactive point and switch, all lines and symbols
Unique network definition algorithm for analysis circuit selection. The DINIS travelling mouse provides the engineer with graphic confirmation of the circuit selected for analysis
Complex site representation

Analysis Features

Network analysis, 3, 2, single phase or SWER, all mixed, unlimited nodes
Advanced transformer modelling including losses
Fault analysis to IEEE and ANSI standards
Two phase unbalanced allocation
Cable resistance (heating) effect
Loss optimisation
Automatic load allocation
Reliability analysis

DINIS enables entire networks to be displayed, colour coded by voltage and represented in both geographic and schematic form, with one workstation holding over 100,00 lines and nodes.

DINIS provides fast answers to "what-if" questions for managing overloads and underloads, minimizing losses and helping to optimize investment plans.

DINIS is the network analysis for grown ups! Networks covering 37 km sqr (including map backgroups), 3000 lines and nodes, 600 transformers are typical model sizes for DINIS.

Optional Specialist Integrated Module

Map Editor/Server
Capture, storage, editing and management of maps. Interfaces to all scanners. Multiple layering, rasterization of vector map and vice versa. Map stitching capability.

DINIS DSQL
SQL like database query and updates. Provides links to databases.

Time Of Day Analysis
The DINIS(E) Time of Day module is designed to allow a DINIS(E) user to examine the effect of the loads on a network varying with time. .

G74/IEC909 Fault Analysis
These are standards which are set by electricity regulatory bodies, e.g. Institute of Electrical Engineers (IEE) to ensure that the electricity networks of distribution and power companies conform to safety standards. G74 are the British standards and IEC909 those set by the EC..

Mutual Coupling
Electrical networks often contain circuits in which lines are constructed in close proximity to each other, especially overhead lines. In these circumstances, the effect of mutual coupling between two adjacent circuits is to alter the zero sequence network and hence fault levels for unbalanced faults, such as L-G. The difference in fault levels between a circuit with mutual zero sequence coupling (MZSC) modelled and a circuit without is significant.

Network Reduction
It is often necessary to carry out network reduction studies to provide a concise summary of fault and load flow equivalents at boundary points within a Distribution network. These are required in order to meet Distribution and NGC needs..

Enhanced Reliability
Developed in line with User needs and market feed back to improve network planning decision making based on historic and periodic reliability criteria..
