The paper introduces a new recording and online modal analysis system that evaluates small signal damping on power systems. Use of the tool as an aid during the commissioning of power system stabilizers at the Kettle generating station that operates both on the AC as well as the DC networks in the Manitoba Hydro (MH) power system is reported. The paper also reports how the same online modal analysis tool was used to confirm the successful operation of the stabilizers in AC mode through some staged tests. Further, modal analysis results of the measurement system are presented that identify and isolate improperly tuned generator controls that introduce under-damped modes on the Manitoba Hydro power system.
