SYS 600C capacity
7.1.
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, mir-
roring, 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 accord-
ingly. 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 5 msg/s/IED), see
Table 7.3-1.
•
The following functions are also needed:
•
One NCC connection (-25%)
•
1 workplace (-5%)
•
The process communication capacity in this case is:
•
75% * (95% * 160 IEDs) = 114 IEDs or
•
75% * (95% * 800 ) msg/s = 570 msg/s
Data logging capacity
7.2.
The data logging capacity concerns logging to disk and is limited by the available disk
capacity. Roughly 1 GB of disk capacity is allocated for event logging and the same
amount for data logging.
