Situation in Wind Power
• Wind power control centre supervises 39
wind turbines from 9 different suppliers.
• With the delivery of the turbine each supplier
provides a disk or CD for his own proprietary
(hidden) communication solution.
• 9 different programs on different machines
(DOS, Windows 98 or NT, Unix) must be
started to communicate with all turbines.
• Integration require costly custom datatranslation and data-mapping components.

Logical Node
IEC 61850
Logical node
Common logical node information
Logical node
information
information independent from the dedicated function
represented by the LN, e.g., mode, health, name plate,
...
Status information
information representing either the status of the process
or of the function allocated to the LN, e.g., switch type,
switch operating capability, ...
Settings
information needed for the function of a logical node,
e.g., first, second, and third reclose time, close pulse
time, and reclaim time of an autoreclosing function.
Measured values
are analogue data measured from the process or
calculated in the functions like currents, voltages, power,
etc., e.g., total active power, total reactive power,
frequency, net real energy since last reset, ...
Controls
are data, which are changed by commands like
switchgear state (ON/OFF), tap changer position or
resetable counters, e.g., position, block opening, ...

Part 10: Conformance Testing
Scope
This part of IEC 61850 specifies methods for
conformance testing of devices
of substation automation systems.
In addition it gives guidelines for setting up test
environments and specifies levels of
interoperability. Thus it enables the investigation
of conformance claims and to establish their
validity.
