9. Control displays the Synchronism-checkAutorecloser, and Apparatus control
functions. The Synchronism-check
and the Autorecloser functions include a
number of function related measurements such as calculated differences of
measurements and number and kind of reclosing attempts. Apparatus control
includes up to 19 functions each with their own set of measurement data regarding
interlocking, breaker and isolator conditions.
10. Scheme communication includes functions that display trip and other signals used
when interzone communication is deployed.
11. Logic displays a choice of functions available to the operator. These are Trip logic,
Event counter, Logic gate, Logic memory and Logic timer set each with their own
set of measurements.
12. Monitoring displays a choice of functions available to the operator. Function
related measurements can be viewed by navigating to the screen for each
individual function. One of the submenus shows the status of the LEDs on the HMI.
13. Communication displays submenus for Remote communication and Station
communication including Receiving interlock information.
All measurement descriptions in this document reflect the maximum number of
hardware units possible in any application. In reality the hardware in the IED will be
chosen according to a particular application. For example, it is possible to equip a 1/1 x
19” case IED with 14 I/O modules. In reality fewer I/O modules may be installed. In
the measurements menu the operator will only see data from the hardware and software
installed.
11.2 IED test mode
Main menu/Test/IED test mode
Displays a setting which is used to activate and deactivate functions so that tests can be
performed without endangering system stability and a setting with which events can be
enabled or disabled.
11.3 View binary input values
11.3.1 Overview
Binary input values display the state of each individual input in the Binary input
modules (BIM). These are indicated with a 1 or 0 depending on whether a signal is
present or not. Binary input modules with enhanced pulse counting capabilities can
receive pulses used for power measurement. The number of pulses received is used to
measure power.
