Multi-terminal subsystem model validation for pacific DC intertie

This paper proposes to validate dynamic model of pacific DC intertie with the concept of hybrid simulation by combining simulation with PMU measurements. The playback function available in GE PSLF is adopted for hybrid simulation. It is demonstrated for the first time the feasibility of using playback function on multi-terminal subsystem. Sensitivity studies are also presented as a result of common PMU measurement quality problem, ie, offset noise and time synchronization. Results indicate a good tolerance of PDCI model generally. It is recommended that requirements should apply to phasor measurements in model validation work to ensure better analysis. Key parameters are identified based on impact of value change to model behavior. Two events are employed for preliminary model validation with PMU measurements. Suggestions are made for PDCI model validation work in the future.
