Grid Quality
Grid Quality
In conjunction with acteno energy metering for network quality analysis and acteno epm, the customer receives a comprehensive tool for monitoring network quality. The need for installing an additional network quality analyzer is eliminated. Measurement of relevant parameters is done according to EN 50160 standard. With acteno energy’s integrated network quality analysis, the customer gains valuable insights for optimizing consumption and generation systems.
- Continuous and permanent monitoring of network quality parameters
- Notification via email in case of deviation from set standards
- Documentation of network quality events in acteno energy performance management
- Generation of reports in PDF format and output of raw data in CSV format
Your benefits
- Elimination of the need to purchase a separate measurement system for network quality analysis, as it is already integrated into the acteno energy smart metering system
- No additional metering cores required, as the transformer metering cores of the billing meter can also be used for network quality analysis
- Independent data acquisition, transmission, and analysis by acteno energy
Specific analysis of network quality, including
- Harmonics analysis
- Voltage dips on individual phases
- Voltage asymmetry
- Current asymmetry
- Exceedance and non-compliance of voltage and frequency limits
- Mean phase currents
- Network frequency (f)
- Total Harmonic Distorsion U THD
- Total Harmonic Distorsion I THD
- Short-term flicker severity (Pst)
In the context of the energy transition and the advancing technological development of power grids, aspects of supply quality are becoming increasingly important.
As a metering point operator, we provide you with a differentiated picture of the quality in the following segments:
- Supply reliability: Type, duration, and frequency of interruptions
- Voltage quality: Defined by European standards
- Service quality
Characteristics of supply quality
Reliability of supply
The reliability of power supply is determined by the frequency and duration of power outages. It indicates the extent to which an electrical supply system is able to fulfill its task of delivering electricity under certain conditions and over a specified period. To assess this reliability, power outages at end consumers (users of the network) are considered and analyzed. Worldwide and in Europe, there are uniform guidelines for defining metrics, such as outage time in minutes per year. These metrics are based on factors that can be influenced by network operators and therefore provide a basis for regulating supply quality. It is important that the collection of this data is feasible without disproportionate effort.
Quality of the electrical voltage
The quality of electrical voltage is determined by European and worldwide standards and is defined by the conformity of the actual voltage values at the consumer’s end with the specifications guaranteed by the network operator. The determinants of voltage quality are diverse and often complex, making it difficult to assign specific causes to particular disturbances. The following factors significantly influence voltage quality:
- The distribution network of the operator and its operational switching processes.
- Feedback from the network due to energy generation facilities and end-user devices, which are only partially controllable by the network operator and mostly through standards or contractual regulations.
- Additional variables such as atmospheric conditions (such as thunderstorms, storms, or frost formation) or external influences (such as cable damage due to construction work) that can cause ground faults or short circuits.
As a result, it is not easy to determine the reasons for a specific impairment during a disturbance. Possible causes may be directly at the affected end consumer, at another consumer in the vicinity, or with the network operator itself. Additionally, it is possible for various causes to overlap, and disturbances and their effects may manifest differently.
