Communication Systems

SERL is developing technologies related to the design, operation and analysis of information and communication systems (computers and wired/wireless communication networks) used for the operation and maintenance of power system infrastructure. Specific examples include demand area power system communication networks and systems for collecting information from substation devices.

Fundamental Technologies

  • Techniques for evaluating radio wave and fiber optic propagation characteristics
  • Communications network control technologies

Major Researches

Core communication technologies for the next-generation grid (TIPS)

For the low-carbon society of the future, SERL proposes an advanced infrastructure for the supply and utilization of electric power (the next-generation grid: TIPS). The goal is to develop operation and control technologies for allowing large-scale interconnections of distributed generations, technologies for preventing large-scale blackouts, and techniques for advanced management of aged infrastructure. To help configure the communication infrastructure required by all of the above, SERL is developing technologies for secure demand-area communications network to communicate and cooperate interactively with customers, wide-area and high-speed control networks for emergency control in the case of power system disturbances, sensor networks for equipment maintenance and operation, and supervisory control of power delivery infrastructure.

Communication media and networking technologies

Regarding communication systems used for the power industry, SERL is developing techniques for analyzing propagation characteristics and technologies for communications network control. Specific examples include developing techniques for predicting radio wave propagation in substation premises with many interfering metal structures, technologies for controlling the propagation of terahertz band waves, and media-integrated communication technologies for multiplexing heterogeneous-media signals through optical fibers.
