SLIDE 6

Visualizing the Decisions

SLIDE 7

What is Real Time Data

Sample inputs 3x more than controlled action
Regulator gate movement effects noticed in

less than 5 minutes

Operations is accustomed to 1-2 second

updates within plant

Ideal monitoring around Whittier Street would

update at least every 30 seconds

SLIDE 8

Ability to Learn from Each Event

There are more

items than can be easily trended together

Trends loose some
f the dynamic

“feel” of watching the system behave

Historical replay example

Which trend line was that?

SLIDE 9

Constraints on the Leading Edge of Event

SLIDE 10

System Constraints Exceeded

SLIDE 11

System Draw Down After Event

SLIDE 12

So Close Together, but Different Responses

DSR83

1 foot difference

Downstream OSIS

SLIDE 13

Optimization of DSR83 Constraint

SLIDE 14

Further Constraint Management

Improvements

Berliner Park Level
Assisted or

Automatic control

f regulator gates
OARS Tunnel

SLIDE 15

Berliner Park Level Sensor

Solar Powered
Readings every 4 seconds
Intrinsically safe instrument
Low powered radio
Direct I/O on radio

SLIDE 16

Real Time Control Feasibility Study

Builds upon lessons

learned through efforts so far

Identify other

possible controls and monitoring

Evaluate how to

apply them to the collection and treatment system
