The subsynchronous interaction between the wind farm’s grid-side converter and the series-compensated transmission line can trigger subsynchronous L-Theanine oscillations (SSO).The wind power system oscillation frequency depends on the actual operational conditions.This paper proposes a repetitive-PI control strategy to mitigate oscillations
With the improvement of industrial requirements for the quality of cold rolled strips, flatness has become one of the most important indicators for measuring the quality of cold rolled strips.In this paper, the strip production data of a 1250 mm tandem cold mill in a steel plant is modeled by an improved deep neural network (the improved DNN) to im
Hypoxia switches the metabolism of tumor cells and induces drug resistance.Currently, no therapeutic exists that effectively and specifically targets hypoxic cells in tumors.Development of such therapeutics critically depends on the availability of in vitro models that accurately recapitulate hypoxia as found in the tumor microenvironment.Here, we
Herringbone grooved aerodynamic journal bearings have better stability characteristics than plane aerodynamic journal bearings.In addition, the use of flexibly supported bearings is one of the efficient way to improve the bearing stability.Therefore, the combination bearing systems have prospects of realization of ultra-high-speed operations.The Br
Library anxiety is a subject which has been searched in international platform in its various dimensions since 1986 in which the concept was first defined.On the other hand, this important subject, in the context of this article, as of the end of 2010 year in which we concluded literature survey, has never been handled and studied on in the scope o
