|Distributed Megawatts is
the second team working on this project for Potlatch.
We are continuing the design of an updated control scheme
for the Compact infrared paper dryers installed in Potlatch's
Lewiston Plant. The goal is to improve the power quality
of the system. Our team is continuing the power computer
redesign, including stepping up the newly developed
algorithm to fit in the existing plant setup.
diagram below represents the current system at Potlatch.
The part of the project we are focusing on is replacing
the power computer. This involves taking out the CPU
card and 4 Digital Trigger Cards and replacing them
all with one new Printed Circuit Board (PCB) we have
designed. We are making use of one PIC microprocessor
for communications with the rest of the system and and
6 PIC's to fire the lamps.
