This paper deals with power quality disturbance generator for the test of STS in power system. The STS used in this system is composed with SCR thyristors. It is necessary to connect the thyristors in series in high voltage system. The major components consisting the generator are SCR thyristors, series transformers, and sliding type auto transformers, therefore, the system reliability is very high...
Synthetic Test Circuit (STC) system for thyristor valve of current-type High Voltage Direct Current (HVDC) typically consists of a low-voltage high-current and a high-voltage low-current source. In order to provide the isolation between each source, auxiliary valve should be inserted, and its voltage and current ratings are greater or equal to those of the test thyristor valve. To ensure the turnoff...
The power loss of a high power voltage disturbance generator is analyzed to design a high efficient generator. The major components of the generator are 3-phase autotransformer, series transformers, and SCR thyristors, which guarantee cost-effective hardware. To maximize the efficiency of the generator the current through these components should be minimized. The only one parameter that can be adjusted...
Synthetic aperture radar (SAR) image performance can be quantified by the impulse response function (IRF) resulting from a ground reference-point scatterer. Since the level of clutter background surrounding the point scatterer affects not only the shape of the IRF but also the relative magnitude of the peak-to-sidelobe ratio (PSLR) of the IRF, the PSLR can be an important measure for SAR image quality...
