SECTION 14
• BESTCOMS™ SOFTWARE
DESCRIPTION
BESTCOMS
™ is a Windows®
based program that runs on an IBM compatible computer and provides a
user friendly, graphical user interface (GUI) for use with Basler Electric communicating products.
BESTCOMS is an acronym that stands for Basler Electric Software Tool for Communications, Operations,
Maintenance, and Settings.
BESTCOMS provides the user with a point and click means for setting and monitoring the in-service relay
or relays under test. The point and click method provides an efficient, fast setup for configuring one or
several relays. This software is provided free with every BE1-700 Digital Protective Relay.
INTRODUCTION
A primary advantage of the 32-bit BESTCOMS is that an actual unit (i.e., operating transmission
protection system) is not required to perform any or all settings and adjustments for any preprogrammed
scheme. Nor is it needed to create a custom scheme complete with settings and adjustments. In addition,
BESTCOMS is identical within all of the Basler Electric Numerical Systems except for differences inherit
in the individual systems. This means that once you become familiar with a BESTCOMS for one system,
you are also familiar with BESTCOMS for all of the systems.
Using the BESTCOMS GUI, you may prepare setting files off-line (without being connected to the relay)
and then upload the settings to the relay at your convenience. These settings include protection and
control, operating and logic, breaker monitoring, metering, and fault recording. Engineering personnel can
develop, test, and replicate the settings before exporting them to a file and transmitting the file to
technical personnel in the field. In the field, the technician simply imports the file into the BESTCOMS
database and uploads the file to the relay where it is stored in nonvolatile memory. (See the paragraphs
on File Management later in this manual for more information on saving, uploading, and downloading
files.)
The BESTCOMS GUI also has the same preprogrammed logic schemes that are stored in the relay. This
gives the engineer the option (off-line) of developing his/her setting file using a preprogrammed logic
scheme, customizing a preprogrammed logic scheme, or building a unique scheme from scratch. Files
may be exported from the GUI to a text editor where they can be reviewed or modified. The modified text
file may then be uploaded to the relay. After it is uploaded to the relay, it can be brought into the GUI but
it cannot be brought directly into the GUI from the text file. The GUI logic builder uses basic AND/OR gate
logic combined with point and click variables to build the logic expressions. This reduces the design time
and increases dependability.
The BESTCOMS GUI also allows for downloading industry-standard COMTRADE files for analysis of
stored oscillography data. Detailed analysis of the oscillography files may be accomplished using
BESTwave
™ software. Updated contact-sensing inputs specifications in Sections, 1, 3, and 12.
This section introduces all of the screens in the BE1-700 Digital Protective Relay with their field layouts
and typical entries. Common program activities such as applying settings, modifying logic, and setting up
password security are discussed. These discussions are application oriented. We explore how the activity
or task can be performed using an appropriate BE1-700 BESTCOMS screen.
BESTCOMS screens are similar to most Windows based GUI screens. You may immediately notice
common features such as the pull-down menu, toolbar, icons, and help prompts when the mouse pointer
is paused over an icon. Some of these features are shown in Figure 14-1. If the Navigation Bar has a right
and left arrow at the extreme right hand side of the screen, clicking on these arrows will shift the
Navigation Bar to allow access to all of the icons on the bar. Like most computer programs, there is often
more than one way to perform an activity or task. These various methods are discussed in the following
paragraphs in conjunction with the appropriate BESTCOMS screen.
