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
network topology and data build from basic mapping
network storage, display and update facilities
with external databases
modelling display, combined or separate
point and switch, all lines and symbols
network definition algorithm for analysis circuit selection. The DINIS travelling mouse
provides the engineer with graphic confirmation of the circuit selected for analysis
analysis, 3, 2, single phase or SWER, all mixed, unlimited nodes
transformer modelling including losses
analysis to IEEE and ANSI standards
resistance (heating) effect
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

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..
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.
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..
Developed in line with User needs and market
