General-purpose model of power-system loads

The paper is concerned with the derivation of a load model for use in studies of power-system dynamics and with he parameters to be used in such a model. It describes some system tests in which small voltage disturbances were imposed on a power-station auxiliary system and on consumer loads. The objectives of the tests were to determine the important factors in the power/voltage response of loads and to explore the possibility of determining the load composition and characteristics from such tests. The parameters obtained from the analysis of the small-disturbance tests on the power-station auxiliary system are used in an attempt to simulate a large disturbance to that system.
