Testing Benefits

• Monitor Oscillatory Dynamics– Base-line system modal properties

• Freq, Damping, Shape, Interaction paths

– Model validation with respect to oscillations– Data base for modal analysis software and research

• Wide-Area Oscillation Damping Control– Evaluate the potential impact of modulation control on system

dynamics– Provide key base-lining transfer functions under varying

operating conditions– Provide comparative information to model-based studies– Evaluate control-system robustness, scaling, and gain properties

Tests• 2009:

– 14 PDCI probe tests spread over the summer, all tests analyzed.– Brake tests: May 6.– Poor system-wide PMU coverage.

• 2011 – 15 PDCI probe tests spread over the summer, all tests analyzed.– Brake tests: July 21.– Poor system-wide PMU coverage.

• 2012: 26 PDCI probe tests, all analyzed, – 26 PDCI probe tests spread over the summer, all tests analyzed.– Brake tests: March 27, Sep. 13.– Good system-wide PMU coverage

• 2013: 26 PDCI probe tests, all analyzed, – 30 PDCI probe tests spread over the summer, 4 tests analyzed.– Brake tests: March 13, April 10, June 19, Sep. 11.– Good system-wide PMU coverage for 4 tests.

• 2014: ~36 PDCI probe tests planned– 3 High-frequency tests planned– Good system-wide PMU coverage.

The Tests

Tests

• Superimpose +20 MW 0.1-Hz to 5-Hz probing signal on to PDCI for 20 min.

• Superimpose +5 MW 1-Hz to 28-Hz probing signal on to PDCI for 10 min.

• Chief Jo 1400-MW, 0.5-sec. pulse.

2014 Probe Test Goals• Continue to monitor NSA and NSB modes. Now have

excellent historical perspective.• Continue to baseline EWA mode. Need to understand

interaction paths and full shape.• Start to baseline MT mode. May need Kemano PMU.• Assist PeakRC in setting and baselining Mode Meter.• PDCI feedback control evaluation

– Continue to monitor controllability – High frequency probe tests:

• Evaluate PDCI response• Evaluate high-frequency content of feedback signals for PDCI

modulation control
