Disturbance prevention

Detect and resolve system anomalies and prevent equipment damage and misoperation.

Issues related to power quality are difficult to identify. In many cases, they occur only occasionally and for a very short period of time, or they lead to a slow degradation of insulating materials with outages to follow after months or even years.

Our AI-based power quality analytics (PQA) service with an optimized measuring infrastructure allows grid operators to detect anomalies early and identify their cause. Our PQ expert system is built on significant experience gained from a variety of previously analyzed disturbances. Combined with PTI Consulting’s full-range power system expertise, this allows us to uncover even complex system interdependencies and provide consultancy for effective mitigation measures.

Disturbance analysis

Detect and resolve the root causes of power system disturbances.

To resolve disturbances, it is crucial to instantaneously understand their root causes. Often, the knowledge of specialists in various fields of grid planning – such as protection, insulation coordination, system dynamics or operation – needs to be combined.

The PTI Consulting team consists of expert consultants specialized in the various fields of power system engineering. They work together to find a technically efficient solution to any power system fault and provide fast disturbance analysis support to grid operators: from data collection and on-site measurements with modern PQ measuring devices to the analysis of reference events. Based on detailed modeling and simulation with the PSS® suite, we help to quickly verify the root cause, and then propose and validate effective mitigation measures.

Plant design and grid optimization

Avoid power-quality-related disturbances in your power system.

Whether in public power supply networks, industrial plants, or wind farms: harmonics, switching surges, or voltage dips can have serious effects on power quality and thus supply reliability.

In the development phase of plants and power systems, our PTI consultants analyze if certain network and load limits are likely to be met by means of model-based power quality simulations. In these cases, we advise on special measures, such as the application of harmonic filters, or the rearrangement of the supply system and the loads. Our consulting services cover the entire process until the measures are implemented.
