In Japan smart grid news, Kobe City Waterworks Bureau has announced it is working with technology partners including Sensus to develop a smart water network.
The utility is running field trials at nine locations including schools and an airport.
The aim is to test communication technology between water meters on the network and the municipal water company.
Partners in the trial include Nippon Telegraph and Telephone West Corporation (NTT West), Kobe City Waterworks Bureau and MIRAIT Technologies Corporation.
Sensus is supplying its FlexNet long-range radio network to deliver meter data.
The meter communication technology company also has a live trial of its long-range 280MHz spectrum in the dense urban environment of Tokyo.
Smart grid universal controller
In other Japan smart grid news, precision measurement company Smart Energy Instruments (SEI) has launched its first smart grid universal controller reference design at a trade event in Osaska this week.
Original equipment manufacturers can use the reference design to build a single intelligent electronic design (IED) with multiple functions to measure and communicate current, voltage and power quality characteristics.
Canadian company SEI’s technology also claims to provide the universal controller with “superior grid visibility”.
Designers can create a family of IEDs such as phasor management units, power quality meters, faulted circuit indicators, wide area monitoring system and advanced protection relays.
The SEI reference design is based on the SGS1010A Analog Front End and the SGS1010D System on Chip (SoC), with two central processing unit cores and 16 digital signal processors.
CEO Jeff Dionne said SEI’s DASLR technology is incorporated into the chipset, providing large-spectrum dynamic response, extreme accuracy, very high-speed processing, low-latency and maximum resolution, all of which are essential attributes of advanced IEDs.
Mr Dionne said: “The industry has needed a new approach to IED development for some time.
“Incumbent brands are now able to deliver superior functionality at a much lower cost and new market entrants can provide innovative solutions in response to new requirements, such as renewable energy mandates.
He added: “This is an exciting time to be in the grid automation market.”
