ABSTRACT: Detailed procedures for the modeling of synthesis load
models (SLM) of actual power network are presented, then the classification
indices based on 1oad characteristics and the principle of load classification
are expounded. Based on the results of general investigation of 220 kV and
330kV substations in China’s power grid, the load characteristics are
classified, and detailed load characteristic investigation of selected
different kinds of typical substations are carried out. By use of statistical
synthesis, the SLM for typical substations, in which the distribution networks
are taken into account, are built; and the modeling results are disseminated
and applied to whole Chinese power grid. Besides, the load model parameters are
evaluated and verified via post-disturbance simulation method. The effectiveness
of the built SLM is validated by the fitting of some disturbance incidents.
