Measurement-based Load Modeling Validation by Artificial Three-phase Short Circuit Tests in North East Power Grid

Abstract

The researches on measurement-based load modeling have been continued for more than twenty years in China. However, since lacking of system measured data of major disturbance, it is doubtful for load model generalization capability, and more attentions are also caused for the issue that whether dynamic simulations adopting the measurement-based load model accord with the real system. The measurement-based load modeling technology was put into practice in North East Power Grid in 2002, and load models based on field measurement were relatively constructed. There were four artificial three-phase short circuit tests in 2004 and 2005 respectively in North East Power Grid, and the measured dynamic data from PMU and load data from load characteristics recorders validated the constructed load models and checked the generalization capability of the load model. The well generalization capability of the measurement-based load models verifies the validation of measurement-based load modeling technology.
