SMIGHT Grid2
An upgrade for your distribution grid
The energy transition and the growth of e-mobility are presenting grid operators with new challenges. As a result, the demands placed on the low-voltage grids are rising. Grid operators need to know where and how the load is changing in order to enable them to expand and operate their grids effectively. Robust and extensive recording of data from the low-voltage grid is therefore essential for mastering the challenges of the energy transition.
The Solution
SMIGHT Grid2 addresses this need and uses patented sensors and IoT technology to measure the current and voltage at local transformer stations and cable distribution cabinets. Grid operators can thus determine with geographic precision over a wide area and in real time where power grids are reaching the limits of their capacity. SMIGHT Grid2 supports you in the following areas:
- Strategic grid planning with live data
- Renewal of operating assets
- Precise load management
- Grid connection inquiries
- Finding and documenting cable breaks and faults
- Operational decision-making on the basis of data
SMIGHT Grid2 thus provides the basis for guaranteeing optimal grid load and a successful energy transition.
All processes covered with SMIGHT Grid2
- SMIGHT sensors record the feeder-specific value of the current with the flow direction and phase angle (cos φ) once a minute in a four-phase process. A separate power supply is not needed.
- The SMIGHT gateway measures a busbar voltage and securely relays the data via LTE to our IoT platform as 15-minute values. The devices are constantly monitored and updated by SMIGHT.
- The SMIGHT IQ Cloud securely stores the data center (ISO 27001) and provides you with all the necessary information in graphic form on a web platform.
- The SMIGHT IQ web platform displays the output load curve, the phase load and the voltage curve and informs you if any of the figures exceed the threshold.
- You also receive regular SMIGHT IQ reports with monthly or seasonal trends and reference values from the respective grid areas.
- The SMIGHT Grid API allows you to transfer data to your grid calculation software or other systems of your choice.
Patented power grid sensor technology
The specially developed sensor technology can be quickly and easily integrated into the existing infrastructure. One SMIGHT Grid2 sensor is used for each feeder. The current’s effective value is determined by means of a four-phase recording taken from the high-frequency sampling of the flow using a clamp-type core current transformer. The synchronously measured voltage in the SMIGHT Grid2 gateway can also be used to determine the load flow direction as well as the active and reactive current. The Grid2 Sensor Flex with four Rogowski coils is suitable for particularly tight installation situations and conductor cross-sections of up to 300 mm².
Plug & Play
The hardware can be installed in less than 60 minutes by your company’s own staff while operations continue. Commissioning is performed by a specially developed app that scans the QR codes on the devices and assigns them accordingly. This is what also makes SMIGHT Grid2 suitable for use across a wide area.
Data transmission und service from one single source
With the SMIGHT Grid2 gateway, the data is securely transmitted via LTE. Our expert service team keeps a constant eye on everything, monitoring the transmission path as well as the devices and providing remote support if required. As a result, from the sensor technology and IoT platform to data visualization, you get a comprehensive solution from one single source, including service.
Once the hardware has been commissioned, you can work with the data right away. The SMIGHT IQ web platform gives you quick and clear insights into your grid, from the station to the feeders and individual phases. You can identify anomalies and their frequency and will be notified by e-mail if any threshold values are exceeded. If necessary, you can take specific action and monitor the situation on the data side.
Data in use
From all the data acquired and experience gained from projects with German grid operators, we have developed the SMIGHT IQ reports. The processed data is a solid basis for daily grid operations and grid planning as well as for expansion and renewal measures.
Open yet secure
Stored in a German data center (ISO 27001), we place the password-protected data at your disposal. Grid calculation tools, GIS or other systems can be easily connected via a programmable standard interface (REST API). The data thus serves as a basis for improved grid models and simulations.
