For multiple grid-connected inverters with active filter function,it makes sense to regulate every unit to output maximum active power from photovoltaic arrays,as well as eliminate the harmonic due to the non-linear loads connected to the electric networks.Naturally,a centralized control coordination strategy was proposed for the purpose of high facility utilization,good harmonic compensation ability and unwanted overcompensation condition.Based on a vector decoupling control scheme and generalized instantaneous reactive power theory,the solution was to allocate the harmonic eliminating task for every inverter according to the instantaneous power margin of each.The grid current always keeps sinusoidal in spite of non-linear load change and output active power change for any inverter.The simulation results validate the efficacy of the proposed coordination strategy. 展开更多

跨文化新闻话语可以是我们的新闻媒体对其他文化的言说,可以是其他文化新闻媒体对我们的言说,可以是我们利用其他文化的新闻媒体对自己的言说,还可以是其他文化新闻媒体对另一文化的言说由我们的新闻媒体报道出来。不同于面对面的跨文... 跨文化新闻话语可以是我们的新闻媒体对其他文化的言说,可以是其他文化新闻媒体对我们的言说,可以是我们利用其他文化的新闻媒体对自己的言说,还可以是其他文化新闻媒体对另一文化的言说由我们的新闻媒体报道出来。不同于面对面的跨文化传播话语,跨文化新闻话语有其自身的区分性特征,如非瞬时性、文本间性、刻板形象、主体间性,而且不一定具有交流性,跨文化新闻话语更多的是文化自省、民族心理需求的一种反映。 展开更多

Canonical transient receptor potential 4(TRPC4) forms non-selective cation channels that contribute to phospholipase C-dependent Ca2+ entry into cells following stimulation of G protein coupled receptors and receptor tyrosine kinases.Moreover,the channels are regulated by pertussis toxin-sensitive Gi/o proteins,lipids,and various other signaling mechanisms.TRPC4-containing channels participate in the regulation of a variety of physiological functions,including excitability of both gastrointestinal smooth muscles and brain neurons.This review is to present recent advances in the understanding of physiology and development of small molecular modulators of TRPC4 channels. 展开更多
