Mask and Parameters

Description

Use this field to add all kinds of information about the component

Detection mode

Use either the internal algorithm (with the analog signal at the connected bus) or an external signal (analog or digital)

Detection mode - external

When external is selected, use either the analog or digital signal at the A or P input pins

Detection slope

Positive

The synchronization is done on the positive slope (rising part) of the reference signal

Negative

The synchronization is done on the negative slope (falling part) of the signal.

Reference phase

Signal at the connected bus to use as reference (A, B or C)

Detection level

Value of the reference voltage at which the synchronization is triggered (kV)

Duration of sensor pulse 'SyncOut'

Whenever an acquisition is triggered and the condition is met, a pulse is output with the specified duration (time steps).

If the time step = 50 us and the duration value is 10, then the output pulse duration will be 500 us

Acquisition start time measurement

Time source

Use only system time. IRIG-B is for legacy

Base unit for sensor 'Time'

(Time steps, Seconds, Minutes, Hours) When showing the POW time sensor in Scopeview, one can see the total circuit time since the beginning of the simulation. This parameter defines how often Time is updated in Scopeview.

Scopeview will always show the graph in Seconds (model unit), but choosing Time-Step will make an update at every time step, which will then show a ramp, whereas choosing Seconds for example will result in step increments of the graph.

Time value in Scopeview does not depend on the simulation Mode (real-time or non real-time). Therefore:

Ports, Inputs, Outputs and Signals Available for Monitoring

Ports

Net_1

Network connection (supports both 1-phase and 3-phase connections)

Inputs

A	Analog signal used for external synchronization
P	Digital signal used for external synchronization
D	Delay: The value is sent directly to ScopeView to create an offset between signals, e.g. to synchronize an acquisition with another acquisition system where a delay between the systems is required to obtain waveforms at the same time

Outputs

None

Sensors

A	Input pin A (activated with external mode and analog)
D	Input pin D (activated with external mode and digital)
P	Input pin P (activated with external mode)
SyncOut	Synchronization pulse triggered when conditions are met
Time	Time elapsed since the beginning of the simulation. See Time Sensor for details.

Example

Let the POW be connected to a 3-phase bus WES7.

Let the POW be configured as follows:

Detection slope	Negative
Reference phase	B
Detection level	200 kV
Duration of sensor 'SyncOut'	1 Time step
Base unit for sensor 'Time'	TimeStep

The following figure shows the acquisition from Scopeview, with:

0.1

Note: if Sync is not checked, POW is ignored, and 0.0 is the moment when the user requests the acquisition.

Let the simulation be done in RTA mode and acquisition requested around 3 seconds after starting the simulation.

0 is detected when phase Reference phase (B = WES7.Vb) crosses the Detection level (200 kV) with the Detection slope (Negative).

One can see that the acquisition was started at 18.195 seconds and finished at 'acquisition start time + time length'. With a simulation time step of 50 µs the values from step 363900 to 365900 are shown.
