Transmission MonitoringTransmission Monitoring

• NB Power oversees the Maritime Control Area

• Standards for responding to loss of load or generation

• NB Power is responsible for maintaining 60 Hz frequency on grid

• We adjust the frequency by raising/lowering load on units

• PI used to demonstrate compliance, prepare reports

Opacity MonitoringOpacity Monitoring

• Provincial regulations stipulate that our Dalhousie plant must report an exceedance if we exceed 20% opacity in any 4 minutes of a 20 minute period> Very difficult to calculate using DCS> Many spikes due to rapping

Solution - PI-API!

Opacity MonitoringOpacity Monitoring

• NT service written in C• Runs on PI server• Tracks opacities for each unit• Should an exceedance occur, it

> generates a report of opacities during the period

> alarms the unit operator
