Capacity and performance
7.1
SYS 600C capacity
This chapter gives an overview of the capacity of SYS 600C regarding the following
functions or aspects:
•
Number of IEDs that can be connected
•
Usage of the following functions: workplaces and process displays, gateway,
mirroring, HSB
•
Data logging (for example, for measurement reports and trends) and event logging
Conditions:
•
The capacity information is only applicable, when no additional software is installed
and/or running in the computer.
•
The average CPU load of the computer must not exceed 50%.
The system size capacity figures follow these principles:
•
A guideline for the maximum process communication (Number of IEDs or Number
of Messages/sec.) is given. This includes the process communication functions and
the logging of data in the process database.
•
If other functions are added, such as gateway or workplaces, they consume computer
capacity and thereby the process communication capacity must be reduced
accordingly. For IEC 61850 the capacity is mainly affecting the number of messages,
and thus it is more important that this is reduced than the number of IEDs.
•
The impact on the process communication capacity of the other functions is given
in percentage.
Example: How many IEDs can be connected over IEC 61850 to SYS 600C that acts as
a gateway with one NCC connection and one operator workplace?
•
Maximum of 160 IEDs can be connected over IEC 61850 (with 12 msg/s/IED), see
Table 7.1.
•
The following functions are also needed:
-
One NCC connection (-25%)
-
1 workplace (-5%)
-
The process communication capacity in this case is:
-
5% * (95% * 160 IEDs) = 114 IEDs or
-
75% * (95% * 1920 ) msg/s = 1368 msg/s
7.2
Data logging capacity
The data logging capacity concerns logging to disk and is limited by the available disk
capacity. Roughly 10GB of dsk is allowcated for event logging and same amount for
data logging.
