Research on Combination of Controllable Reactor and Magnetic Saturation Transformer
Zhiyou Ren,Yan Zhao,Xiaoyu Sun,Yue Han,Xin Sun 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.7
With intermittent energy grid connected, the requirements of transformer and reactive power compensation are developed. A novel combination technique of controllable reactor and magnetic saturation transformer is proposed in this paper. The optimal control target is implemented by combining the advantages of controllable reactor and magnetic saturation type transformer to suppress flicker of voltage effectively. The corresponding mathematical representation and the equivalent circuit are presented. The design and realization approach of this kind of transformer is described. The traditional transformer capacity can be promoted effectively.
A New Technology of Comprehensive Islanding Detection
Linlin Gao,Zhiyou Ren,Zhongqiang Ge,Aijun Zhang 보안공학연구지원센터 2016 International Journal of Hybrid Information Techno Vol.9 No.6
With the widely application of the distributed generation technology, micro grid islanding detection technology has been greatly developed. A new type of islanding detection technique is proposed in this paper. The new detection technology has realized the rapid, efficient, stable and reliable islanding detection, and achieved the zero non detection zone. At the same time, which put money into limit in minimum range. This paper presents the principle of islanding comprehensive detection technology. This paper designs and describes the method to realize the new islanding detection technology. The new technology makes up for a series of shortcomings,such as the non-detection zone (NDZ) is larger of the local testing technology. And it also overcomes a great many shortcomings of the remote detection technology, such as a big investment and too single.
Control and Research on Blade Vibration of Wind Turbine
Shu Liu,Minghao Zhang,Zisong Xiao,Zhiyou Ren 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.7
This article takes control of fan blade vibration as the main body, introduces a new type of intelligent materials -- Electro rheological fluids, focusing on explain the smechanical and electrical properties of electro rheological fluid explain. The application of electro rheological technology to practical use in the performance of electro rheological fluids, control the occurrence of electro rheological effect, so as to achieve active vibration control effect on leaf and model simulation and eventually realize the effect of blade vibration weakened.
