Abstract. In recent years, the installed capacity of wind-driven power is increasing continuously in China, but the main measure for long-distance transmission with wind power integration now is series capacitive compensation due to the inverse distribution of wind energy resources and load center in China. However, similar to the thermal generator set, the sub-synchronous oscillation phenomenon may also occur in the wind generation set when the power is transmitted via the fixed series compensated line or HVDC system.This article will discuss how to suppress similar problems in the large-scale wind farms using SVG according to the experience of some Chinese power plants to suppress the sub-synchronous resonance using SVC and SVG in the past two years.
Modern radar systems should transmit different waveforms according to different environment. Waveform design is an important problem in radar system design. In this paper, we compare two waveform design methods based on MI and SINR with the signal model of a Gaussian target ensemble in ground clutter. The simulation results show that for the different tasks of radar, the energy allocation modes are different. Finally, the whole paper is summarized.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
