Moreover, information assortment and information processing are purposeful blocks of the third-party good sensor producer utility. The good sensor utility resolution have to be already deployed in the identical AWS account and Area that you’ll use for the dashboards.
This resolution makes use of QuickSight SPICE (Tremendous-fast, Parallel, In-memory Calculation Engine) storage to enhance dashboard efficiency.
Sensor standing dashboard
When lots of or 1000’s of line sensors are put in, it’s vital for distribution engineers to know the standing of all good sensors regularly and repair points to make sure good sensors present real-time data for operator decision-making. Assuming a utility has 5,000 good sensors put in, even when only one% of the sensors have communication points (a sensible situation based mostly on utility expertise), distribution engineers must verify and troubleshoot 50 sensors per day on common. The good sensor communication losses could possibly be attributable to low mobile sign energy, low energy provide, or deliberate or unplanned outages. If it takes 10 minutes to research one sensor, it’s going to trigger the engineering group round 500 minutes per day simply to research the questionable good sensors.
Slightly than checking good sensor data from totally different purposes or techniques to seek out solutions, a sensor standing dashboard solves this downside by aggregating standing statistics throughout all sensors by totally different attributes, together with sensor location, communication standing, and distributions in several areas, substations, and circuits.
Within the following sensor standing dashboard, a hypothetical utility has 102 good sensors (every location wants three sensors for phases A, B, and C) deployed in 5 substations and 6 circuits. Throughout regular operations, good sensor studies load information each 5–quarter-hour, and the occasion information (totally different fault occasions) might come at any time relying on the circuit scenario.
A number of panes are designed to assist distribution engineers reply vital questions on good sensors and facilitate troubleshooting in case communication points occur to good sensors:
- Abstract – The highest abstract pane supplies a fast look of the good sensor statistics, equivalent to variety of substations, circuits, good sensors with good communications, or good sensors which have communication points.

On this case, 4 of the sensors have communication points, that are proven in pink on the map. The operator can establish the questionable sensors, zoom in, and decide the precise location of those sensors. When operators choose up the questionable good sensors, the geo-map can auto deal with these good sensors as effectively.
- Sensor Standing By Substation and Circuit – This pane provides operators a look of good sensors by substation and circuit, equivalent to variety of wholesome good sensors and variety of sensors with communication points.
- Unhealthy Sensor Particulars – This pane supplies details about questionable good sensor information.
- Mobile Communication Sign Power Distribution – Good sensors transmit information to the cloud utilizing mobile communication. If the sign energy is decrease than -100 dBm to -109 dBm (thought-about poor sign of 1 to 2 bars), the sign may be too weak for the sensor to transmit information. Distribution strains present energy to the good sensors. If the road present is decrease than 5-10 Amps, the sensor could not have sufficient energy to transmit information as effectively. Due to this fact, mobile communication energy and circuit hundreds present vital data for operators to slim down the potential root causes of the good sensor communication loss points. The Mobile Communication Sign Power Distribution pane supplies this data. Pink dots signify good sensors with both very low sign energy or very low circuit load, orange dots present average sign energy and circuit load, and inexperienced dots are the sensors with sturdy sign energy in addition to massive circuit load.
- Good Sensor Well being Standing Pattern – Though real-time data is necessary to know the good sensors’ standing stay, it’s vital to study the well being pattern of good sensors as effectively. The Good Sensor Well being Standing Pattern pane supplies a sample displaying whether or not the general operations of the good sensor are higher or worse by week or day. Operators can select the time vary, substation, or circuit to study extra granular data.
- Sensor Distribution by Substation and Sensor Distribution by Circuit – These panes assist the operator study the good sensor deployment distribution data.
- Good Sensor Checklist – This sensor element pane supplies complete data of the good sensors in a tabular view in case the operator desires to look or kind sensors by element data.
With aggregated good sensor information (geo location, mobile sign energy, distributed circuit energy circulate), operators can rapidly establish problematic sensors and slim down the attainable root causes. This strategy can save a big period of time performing sensor upkeep and troubleshooting—as much as 90% or extra.
In future posts on this sequence, we’ll present you how one can use the paginated studies operate to generate every day studies to enhance the operational effectivity much more. The communication pane additionally exhibits the good sensor distribution utilizing a bar chart, and supplies insights of good sensor deployment data based mostly on area, division, substation, and circuit.
