System Dynamic Model Validation using Real-Time Models and PMU Data Conference Paper uri icon

abstract

  • © 2018 IEEE. High-resolution synchrophasor data recorded during disturbances has made dynamic model validation more feasible. While several papers discuss the validation of individual components such as governors and exciters, few consider the validation of the system model as a whole. It is a challenging problem for larger systems due to the sheer number of dynamic models, and hence the states and parameters involved. This paper describes the process of validating the entire system model, up to an interconnect level using an actual disturbance event and the PMU data captured during it. We use the state estimator snapshot captured just before the inception of the disturbance, which is also known as the real-Time model. The paper details the important steps of setting up dynamic model data in these real-Time models, and addresses issues commonly encountered during validation such as correcting 'bad data'. The methodology is illustrated using an actual large system model.
