The ac power stabilizer proposed here has a simple construction and high performance. | |
The controlled stabilizer can reduce the supply voltage distortion and adjust the load voltage within very short time. | |
01 Oct 2019 22 Citations | The proposed control functions are capable of providing accurate performance with fast frequency response for AC grids with the existence of both load variations and DC voltage fluctuations. |
Simulation results show the ISEC can provide better damping and voltage regulation performance, compared with the CSEC without parameter adaptation scheme and the conventional power system stabilizer. | |
Also, small signal stability is more sensitive to the ac voltage controller's gain than to the power controller gains. | |
01 May 2018 | Therefore, it is very important to study the influence of transient parameters on the voltage stability of AC-DC system. |
20 Jul 2008 | Simulation also shows a power system stabilizer (PSS) providing frequency feedback to the automatic voltage regulator (AVR) significantly enhances the system robustness to large disturbances, while reducing the AVR gain has little effect. |
01 Dec 2014 | This result makes it possible to point out how supply voltage fluctuations can decrease the RAS, up to impairing voltage stability not only for large, but even in case of small perturbations. |
34 Citations | The effect of the operating point of a VSC-HVDC link and the control strategies employed can substantially affect the electromechanical oscillatory behavior of the ac network as well as the dc-side dynamics. |
The impact of ac-bus voltage control on dc-bus voltage control stability can be revealed by investigating the impact of ac-bus voltage control on damping and restoring components essentially. | |
06 Apr 2008 | Simulation results show that the fluctuations of frequency and voltage are diminished remarkably, and the stability is improved by adopting the method proposed. |
55 Citations | Further, when the ac voltage control (AVC) is disregarded, a dynamic stability margin is analytically derived, and operation beyond the margin will result in monotonic drift. |
25 Citations | Thyristor-based onload tap-changing AC voltage stabilizers are cheap and robust. |
44 Citations | By electrically coupling dc voltage and ac frequency, power disturbances in ac or dc sides will cause almost identical variation degrees in both ac frequency and dc voltage. |
01 Sep 2017 | Thus, it is possible to attenuate the fluctuations of the DC voltage by virtually enhancing the equivalent capacitance of the system. |
23 Citations | Voltage instability following disturbances under very weak AC-system conditions can also be avoided. |
The research reported in this paper indicates that the filter capacitor will accumulate and dissipate increased amount of charge when the rectifier is subjected to ac source voltage fluctuations. | |
47 Citations | The method can be used to evaluate the effects of dc modes of operation, ac system operating conditions and VAr compensation schemes on the combined system voltage stability. |
