12.7 Testing the protection functionality
GUID-125B6F28-D3E5-4535-9CD6-6C056B79F496 v2
Each protection function must be tested individually by secondary injection.
• Verify operating levels (trip) and timers.
• Verify alarm and blocking signals.
• Use the disturbance handling tool in PCM600 to evaluate that the protection
function has received the correct data and responded correctly (signaling and
timing).
• Use the event viewer tool in PCM600 to check that only expected events have
occurred.
12.8 Forcing of binary input/output signals for testing
12.8.1 Forcing concept
GUID-3FD8C676-10E5-432A-8CD5-4643299AD794 v2
Forcing of binary inputs and outputs is a convenient way to test wiring in substations
as well as testing configuration logic in the IEDs. Basically it means that all binary
inputs and outputs on the IED I/O modules (BOM, BIM, IOM & SOM) can be set to a
value (i.e active or not-active), selected by the user, while the IED is in test mode. For
inputs, this is true regardless of the actual signal voltage present on the input. For
outputs, any output relay can be forced to be active or not, regardless of the current
requested state of the output in the IED logic configuration.
Be observant that forcing of binary inputs and outputs on an IED, with
inappropriate setup, can result in potential danger.
12.8.2 How to enable forcing
GUID-50280F59-A98C-4E48-AB6D-2B4C138943DD v1
To enable forcing, the IED must first be put into IED test mode. While the IED is not
in test mode, the LHMI/PCM600 menus that relate to forcing will not have any effect
on the input/output status due to safety reasons.
