Kenda develops new metering system technology for Winnington
CHP plant
As part of a £200,000 contract for the supply of a complete
tariff and operational metering
system for the Winnington CHP plant in Cheshire, Southampton-based
Kenda Electronic Systems has
come up with a new design that eliminates the need for the transducers
that would normally be used to produce analogue 4-20mA signals
for operational metering.
Under the terms of the contract, which was awarded by Alstom
Power Plants Ltd, Kenda will supply three tariff and operational
metering cubicles for use
at the main Winnington site and two nearby substations at Poppy
Bank and Lostock. The CHP plant is being designed and built by
Alstom Energy Systems for PowerGen to provide steam and power
to ICI Brunner Mond.
The Kenda system utilises the latest CEWE intelligent Prometers,
which not only generate the pulsed outputs required for tariff
metering purposes but also provide serial data via an RS232 interface.
Kenda has used its expertise to design a special DAC processor
system that converts the data into the analogue 4-20mA values
required for operational metering and transmits it for remote
reading at Winnington.
In addition, the Kenda system will include the company¹s
own range of Meteor data collectors, data concentrators and operational
metering summators, a local collector station, a local interrogation
unit, fibre-optic transmitter and receiver units, asynchronous
fibre-optic modems and voltage failure alarm relays.
Having supplied metering data collection equipment to all
of the major power companies in the UK, Kenda is believed to
have installations located at all Grid supply points and all
of the main power stations, as well as several other CHP plants.
