Transient voltage stability enhancement using Static Synchronous Compensator

2014 International Conference on Advances in Electrical Engineering (ICAEE), 2014
This Paper analyzes the application of Static Synchronous Compensator (STATCOM) to prevent the transient voltage instability of power systems due to the presence of large induction motor loads at the terminals of long transmission lines. The analysis is supported by transient time simulations for the complete power system following large disturbances ...

Voltage stability as affected by static load characteristics

IEE Proceedings C Generation, Transmission and Distribution, 1993
Voltage stability is analysed as a dynamic phenomenon associated with the excitation field dynamics of synchronous machines. It is shown that, for constant impedance loads, a single machine powersystem is voltage stable for all reasonable operating conditions.

STATIC LOAD MODELLING AND VOLTAGE STABILITY INDICES

International Journal of Power and Energy Systems, 2009
This paper analyzes the performance of some of the widely used voltage stability indices, namely, singular value, eigenvalue, and loading margin with different static load models. Well-known ZIP model is used to represent loads having components with different power to voltage sensitivities.

Static voltage stability analysis of eskom eastern grid

2016 IEEE International Conference on Renewable Energy Research and Applications (ICRERA), 2016
High voltage direct current (HVDC) transmission offers several operation advantages over high voltage alternating current (HVAC) transmission systems. HVDC transmission lines have no frequency and hence minimal problems of harmonics, oscillations or transients; they actually damp out transients with effective controllers. Precise and fast power control

Voltage stability analysis using static and dynamic approaches

IEEE Transactions on Power Systems, 1993
The authors discuss voltage stability analysis of power systems using static and dynamic techniques. Using a small test system, results of time domain simulations are presented to clarify the phenomenon of voltage instability and to better understand modeling requirements. The same system is then analyzed using a static approach in which modal analysis

Global parametric polynomial approximation of static voltage stability region boundaries

2017 IEEE Power & Energy Society General Meeting, 2017
A novel method for globally approximating the static voltage stability region boundaries (SVSRBs) of power systems is proposed by applying parametric polynomial approximation to the criterion equation which defines the SVSRB. Known as the Galerkin method, the implicit function portraying the SVSRB is described as a linear combination of basis ...

Static Voltage Stability Analysis under Different Accident Conditions

2019 4th International Conference on Intelligent Green Building and Smart Grid (IGBSG), 2019
The study of static voltage stability is actually based on asymptotic stability, which is affected by the operation state of the power grid. In this paper, the voltage stability margin index is deduced, and the stability margin of the existing power grid under different actual working conditions is analyzed based on the proposed index.
