36 - Interface Protections IPS
Description
The
Interface Protections IPS
function allows you to manage malfunctions on systems that can
work thanks to the energy produced by renewable and local energy sources, in particular a lack
of power, e.g. due to a malfunction on the MV voltage side.
The function is available for all Ekip Hi-Touch Trip units and meets the CEI 0-16 standard.
All the parameters and measurements of the function are available via Ekip Connect. In any case,
the Trip unit allows setting the protection
59 S1, V DIR, V INV
and the control thresholds
Voltage
stability, Frequency stability
and
F W1
presented below.
IMPORTANT: for full details see the Technical Catalog (see page 4) or the
function's White Paper (see page 12).
59.S1 Protection
[ANSI 59S1]
If the maximum average value of the three line-to-line voltages calculated in a 10-minute moving
window exceeds the threshold for a time longer than the one set, the protection sends the TRIP
command.
The protection submenu is available in the
Protections-Advanced
menu, where the following
parameters can be set:
Parameter
Description
Default
Enable
Enable/disable the protection and the availability of the parameters
in the menu
OFF
Trip
enabling
Activate/deactivate the sending of the opening command. If
disabled, the alarm and the exceeding of the protection time are
managed only as information
OFF
Threshold
Defines the value that triggers the protection.
The value is expressed both in an absolute value (Volt) and a
relative value (Un), which can be set in a range:
1 Un .. 1.3 Un with 0.05 Un steps
1.1 Un
Time
The trip time. The value is expressed in seconds, which can be set
in a range: 3 s .. 999 s, with 3 s steps
3 s
Constraints, limitations, and additional functions
From the service connector (via Ekip Connect) or with system bus communication it is also
possible to access the block functions, see page 74
Protection V
DIR [ANSI
27VD]
If the direct sequence measured by the Trip unit exceeds or falls below the Udir threshold
(depending on the direction set), the corresponding alarm is activated (TRIP not envisaged).
The protection submenu is available in the
Protections-Advanced
menu, where the following
parameters can be set:
Parameter
Description
Default
Enable
Enable/disable the control threshold and the availability of the
parameters in the menu
OFF
Direction
Defines whether the sequence control is performed as a result of
drops (Down) or increases (Up) of the measured sequence
Down
Threshold
Defines the value that triggers the alarm.
The value is expressed both in an absolute value (Volt) and a
relative value (Un), which can be set in a range: 0.1 Un .. 1.5 Un
with 0.05 Un steps
0.8 Un
