Grid Viewer

The Grid Viewer displays all elements and their worst state during the selected time range. Navigating or zooming the map does not affect the List of Violations or the Plots.

You can search for elements using the search box. In low voltage mode, results include elements from other grids in the same project. Clicking a result opens the element inspector, which also appears when clicking an element on the map.

Clicking an element focuses it and shows its data in the inspector. If the element is a bus, its prosumers are listed under "Prosumers at Bus".

Ctrl-click (Cmd-click on macOS) adds an element to the selection. Selected elements are highlighted in blue. Clicking a selected element again removes it from the selection.

Note: Focus and selection are independent. Only one element can be focused, but multiple can be selected.

List of Violations

Displays all elements violating Operational Limits, grouped by limit type and element. Values in the warning range are yellow; violations are red.

Operational Limits can be modified or reset via the settings icon. Changes apply to all Monitoring pages in the project.

Each list item represents a time span with warnings or violations. The left color bar shows the worst-case category. Columns 2–5 show the split between warning and violation durations.

Clicking an item expands the violating elements. Clicking an element shows detailed occurrences (date, time, duration).

EN-50160 Compliance

PQ devices follow EN-50160 rules. Limits are not shown or editable, as they are derived from the standard.

• Static violations (threshold exceeded regardless of time) are yellow.
• Actual violations (threshold exceeded over time) are red.

EN-50160 Rules

• Voltage Band

  • Low voltage: <0.85 pu or >1.1 pu, or 0.85–0.9 pu >5% of time/week
  • Medium voltage: <0.85 pu or >1.15 pu, or 0.85–0.9 pu or 1.1–1.15 pu >5% of time/week

• Voltage Asymmetry
  Negative sequence voltage >2% of positive sequence voltage >5% of time/week

• Harmonic Voltage
  Harmonic voltage exceeds order-specific limit >5% of time/week

Order	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20	21	22	23	24	25

• Total Harmonic Distortion Voltage
  8% of nominal device voltage

• Frequency

  • Interconnected: <47 Hz or >52 Hz
  • Islanded: <42.5 Hz or >57.5 Hz, or 42.5–49 Hz or 51–57.5 Hz >5% of time/week

• Long-Term Flicker
  1 for >5% of time/week

• Ripple Control Voltage
  Exceeds frequency-specific limit >1% of time/day

• Voltage Events
  Alerts for overvoltage, undervoltage, and outages

Plots

Two plots are shown and can be controlled independently. Fullscreen mode allows detailed inspection without affecting the Monitoring page time range.

Warnings and violations are shown in the background. Hovering reveals affected grid elements.

Available Measurements

• Overall Apparent Power (VA) – in pu relative to device rating
• Voltage (pu) – relative to nominal voltage
• Overall Current (A)
• Overall Active Power (W)
• Overall Fundamental Reactive Power (var)
• Active Energy (Wh)
• Reactive Energy (varh)
• Overall cos(φ)

PQ Device Measurements

If power quality (PQ) measurement devices are installed, the following measurements and events are available for these devices in addition:

• Ripple Control Voltage (pu)
• Total Harmonic Distortion Voltage (%)
• Harmonic Voltage (%) – relative to EN-50160 limits
• Phase Sequence Voltage (V) – positive, negative, zero
• Unbalance Voltage (%)
• Short-Term Flicker
• Long-Term Flicker
• Frequency (Hz)
• Overvoltage Events – 1 during event, 0 otherwise
• Undervoltage Events – 1 during event, 0 otherwise
• Voltage Outage Events – 1 during event, 0 otherwise

Use dropdowns above plots to switch measurements.

Time Navigation

Controls the time range for the Monitoring page. The left slider shows alerts; right buttons and pickers allow date selection.

To zoom: click and drag the slider.
To pan: Shift + drag left/right.
To view all simulations: click All.
To view one day: click Day.
Use arrow buttons to move the selected range forward or backward.
