Accessibility of data
Usually utilities use Geographic Informa-
tion Systems (GIS) to store their assets.
No matter how well the databases are
maintained, it can be quite a task to visu-
alize the trajectory of just a single cable
with its joints on a map. Moreover, there
is no information about its behavior in
the network with changing loads.
GIS systems are simply not designed to
do calculations nor present calculations
results.
For calculations on the distribution
network, load fl ow applications such as
Vision Network Analysis are used. Each of
these applications work with schematic
views of the network.
Vision Grid Navigator simultaneously
presents the geographical information
from the GIS system, with the load
fl ow information from Vision Network
Analysis, or with live data that come from
modern “smart” grids.
Management decision tool
Therefore Vision Grid Navigator makes it
possible to actually make good use of
the multitude of data every network gen-
erates on an every day base. It provides
stunning visuals, allowing better deci-
sion making.

Overview
Short-circuit power in a rural area
For optimal benefi t of Vision
Grid Navigator Phase to Phase
recommends a double screen
with 3D mouse.
Vision Grid Navigator makes it possible to geographically navigate your networks. Geographic and schematic view of networks act together seamlessly. Vision Grid Navigator uses DirectX™ for fast performance drawing and eye-catching visualisation techniques.
Phase to Phase
Phase to Phase focuses on software development
for transmission and distribution network analy-
sis. The vision is to introduce and enhance the
network analysis for a broad range of engineers
by means of innovative products.
The fulfi lment of this vision is supported by the
growing sense of cost in planning, development
and management of the electrical infrastructure.
The products are used by electricity companies,
industry and consultants for network develop-
ment and analysis.

colours change when, for example,
another view is selected or a calculation
is done.
Interaction
The user can select lines or nodes by
clicking them or drawing a selection rect-
angle in the geographic view. The
selection in the schematic view is au-
tomatically updated. When the mouse
pointer moves over nodes or lines they
start blinking. In this way the complete
trajectory of a specifi c cable can easily be
seen. When the mouse pointer moves
over lines lying upon each other, an
extended hint is shown with the informa-
tion of each individual line.
The information given in the hints can
be confi gured by the user.
Filters
The results of the load fl ow calculation
can be fi ltered by an adjustable selection
criterion. There are two type of fi lters one
for line loads and one for nodal voltages.
If the user selects a fi lter, the whole net-
work is drawn in a gray colour. Then for
instance, only those lines can be high-
lighted that have a load of more than
70 percent. When adjusting the fi lter
sliders, the objects that meet the criteria
are instantaneously highlighted.
3D scene
The 3D map model implementation
enables views from a certain horizontal
and vertical angle towards the scene.
The 3D model gives an extra dimension
for presentation purposes. The user can
select 3D bar graphs for viewing calcula-
tion results such as nodal short-circuit
power or nodal voltages.
Also, some attributes of nodes such as
amount of load, generation or number
of customers can be shown in 3D bars.
In this way the geographic distribution
of this kind of information can easily be
interpreted and used within the utility.
Overlays
Different map overlays can be imported
and shown on the map. The import fi le
format is the widely used Google Earth
format KML.
For instance new plans for developing
new residential or industrial areas can be
imported and taken into account when
designing networks.
Aerial photographs
When more detail is wanted aerial pho-
tographs can be shown as background.
The photographs have a resolution of
0.25m per pixel. The accuracy of this
photographic background on the Dutch
RD projection grid is better than Google
Maps/Earth’s implementation.
The photographic background has the
same performance as the map.
Practical approach
With Vision Grid Navigator the Vision
Network Analysis application is extended
with an geographical viewer and editor.
Instead of the detailed and demanding
maps used in GIS applications a simple
but widely used Falk digital map is taken
as a background. On this map locations
and surroundings are easily identifi ed.
Questions like: “On which side of the
road is a cable buried?” or “Is a specifi c
load in an industrial area?” are quickly
answered.
Implementation
The map can be zoomed fl uently from
country to street level thanks to a high
speed tile implementation. The whole
map is implemented as a DirectX™ 3D
model and can be tilted and rotated.
The use of DirectX™ enables fast semi-
transparent polygons and bars, blinking
of lines and blinking of nodes.
Navigation
The main screen of Vision Grid Naviga-
tor consists of a map area and a tabbed
page with a tree view component on
the left. In this tree view networks can
be added. Most Dutch utilities subdi-
vide their service area into separate
MV networks. Each network in the tree
view correspond with a blue square on
the map and represents the location
of the network. By double clicking on a
blue square or item in the tree view the
corresponding network is opened. The
network is drawn schematically in Vision
Network Analysis, and geographically in
Vision Grid Navigator.
Geographical coordinates
In Vision Grid Navigator nodes, lines and
joints are shown on the map when their
geographical XY-coordinates are present.
These coordinates can be imported from
the GIS of the utility. A line, e.g. a cable,
can have many coordinates according to
its trajectory. A node, e.g. a distribution
transformer station, always has one co-
ordinate. When the trajectory of a line is
not known it will be drawn as a straight
line between its nodes.
In edit mode the user can graphically
move, add or remove coordinates from
lines and nodes.
Appearance
In the tab page on the left of the screen,
several settings can be made that
change the appearance of the drawn
scene on the map. With sliders, line
width, node size, sleeve size and text
size are adjustable. An adjustable trans-
parent colour layer is available for better
contrast between network and map
background.
The colour of the lines and nodes in
the geographic view correspond to the
colours in the schematic view. These
