The Study Of Measurement-based Load-modeling Parameters And Their Influences On Dynamic Simulation

In this thesis, load modeling system program is adopted, to analyzesensitivity on load model parameters of inductive motor, and to analyze theinfluence on reactive power resulting from each parameter of motor loadmodel occurring perturbation respectively in system measurement places.Combined with measured data through PMU in actual electrical network,compare load model with the common used by simulation software, byadjusting parameters of systematic load model in PSASP. In addition, discussthe comparison result of load shifting from 220KV to 66KV via transformerin PSASP, regarding the issue about direct application of load model in highvoltage side while constructed in low voltage side. What is more, preliminaryworks of simplifying load-modeling parameters is done, and compare theparameters simplified with those non-simplified both in curve fitting andsimulations added into PSASP. Finally, the author of the thesis also refers tothe subsequent research in the future.
