This chapter describes the EnerVista UR
Plus
Setup software.
Introduction
The EnerVista UR
Plus
Setup software provides a graphical user interface (GUI) to configure,
monitor, maintain, and troubleshoot the operation of UR
Plus
-series devices connected
locally to a computer or over local or wide area communications networks. The software
can be initiated in either offline (not communicating) or online (communicating) modes
with a UR
Plus
-series device. In offline mode, a device settings file can be created or
configured for eventual downloading to that device. In online mode, the settings and
actual values of a UR
Plus
-series device can be configured or monitored utilizing real-time
communications. The software provides the tools to integrate information measured by
the D90
Plus
into DCS or SCADA monitoring systems. Convenient COMTRADE and sequence
of events viewers are integrated. This allows the user to carry out post-mortem event
analysis to ensure proper protection system operation.
Settings templates
Settings file templates simplify the configuration and commissioning of multiple devices
that protect similar assets. An example is a substation that has 10 similar feeders
protected by 10 UR
Plus
-series relays.
In these situations, typically 90% or greater of the settings are identical among devices.
The templates allow engineers to configure and test these common settings, then lock
them so that they are not available to users. For example, locked settings can be hidden
from view for field engineers, allowing them to quickly identify and concentrate on specific
settings.
The remaining settings (typically 10% or less) can be specified as editable and made
available to field engineers installing the devices. These are settings such as protection
element pickup values and CT and VT ratios.
