01 Jan 2001-pp 344-349
TL;DR: In this article, the authors address the issue of measurement-based power system load model development and propose a first order generic dynamic, load model based on the test results, which is in a transfer function form and it is suitable for direct inclusion in the existing power system stability software.
Abstract: The paper addresses the issue of measurement based power system load model development The majority of power system loads respond dynamically to voltage disturbances and such contribute to overall system dynamics Induction motors represent a major portion of system loads that exhibit dynamic behaviour following the disturbance In this paper, the dynamic behaviours of an induction motor and a combination of induction motor and static load were investigated under different disturbances and operating conditions in the laboratory A first order generic dynamic, load model is developed based on the test results The model proposed is in a transfer function form and it is suitable for direct inclusion in the existing power system stability software The robustness of the proposed model is also assessed

TL;DR: In this article, the authors developed an induction motor with different types of shaft loads to model real and reactive power changes to power system Voltage (∆V), frequency(∆f) random changes.
Abstract: The power system consists of composite loads with different characteristics. To aggregate these and represent in equivalent models, is important to develop appropriate load modeling. A composite load consists of static and dynamic load. The main componment of dynamic load, is the induction motor. So it is important to model dynamic nature of an induction motors with shaft loads accurately. The main objective of this paper to develop an induction motor with different types of shaft loads to model of real (∆P) and reactive (∆Q) power changes to power system Voltage (∆V), frequency (∆f) random changes. The new developments are to consider cases where the system affects the load as well as having the load affect the system. A new tool to examine this case is presented. It is really important to verify objective truth by experimental analysis. So, the second objective of the paper is to analyze the measured data from a QLD substation to confirm the model.

TL;DR: The need that selection criterias between the two methodologies must be defined in the IEEE 3002.7–2018 standard is revealed and for isolated systems is highly recommended to perform an analysis in the time domain.

TL;DR: In this article, a new idea of using a DC generator as a permanent magnet synchronous motor (PMSM) load has been presented, based on it, controlled the DC generator armature current to simulate typical PMSM load system has been proposed.
Abstract: This paper presented a new idea of using a DC generator as a permanent magnet synchronous motor (PMSM) load. Based on it, controlled the DC generator armature current to simulate typical PMSM load system has been proposed. The simulator controller is basically composed of by exciting current controller and armature current controller. In order to increase performance of the proposed device, an improved Composite control strategy for armature current was discussed. Meanwhile, build a base on TMS320LF2407DSP load simulator system has been developed, Very encouraging results are obtained.
