Power Quality

Ensuring power quality in a phase of energy transition

Increasing power feed-in from renewable resources poses new challenges for municipalities and distribution system operators.

The stable supply of electric power is any grid operators top priority. To avoid fluctuations in power quality and prevent disturbances, grid monitoring, control, and automation systems need to be adapted and optimized across all voltage levels.

Power Generation

Maintaining control of distributed power producers 

Ensuring grid stability is becoming increasingly complex.

The vast number of small distributed power producers calls for new strategies to ensure consistent power quality. Identifying, locating, and eliminating disturbances and faults as well as the flexible, quick balancing of power production and load consumption require integrated hardware and software solutions that work smoothly together.
