1Development and Application of Lightning Protection Technologies in Power Grids of China显示文摘In recent years,along with the rapid expansion of power grids,the increasing complication of grid structures,and the development of smart grids and energy technologies,the lightning protection of power grids becomes increasingly prominent.Power grids of China have acquired significant achievements on lightning protection technologies,which are reviewed in this paper.A technical route of lightning protection is introduced in detail; it allows us to find problems through detection and measurement of lightning,to analyze problems through evaluation and simulation of lightning,to solve problems through lightning protection measures,and to prevent problems through hazard risk warning of lightning.Following the route,the technical breakthroughs of these four aspects in China are presented,including the chinese lightning detection network(CLDN),natural lightning observations,lightning faults detection at transmission lines,lightning current measurements,progresses in lightning distribution maps,lightning fault replays,lightning hazard risk evaluations,and lightning simulated experiments,as well as novel lightning protection measures.The practical devices and systems corresponding to the technologies mentioned above are also introduced and discussed.Due to the progress of lightning protection technologies in recent years,despite the rapidly growing length of transmission lines in China,the lightning accident rate is controlled at a certain level.GU Shanqiang CHEN Jiahong FENG Wanxing ZHAO Chun FANG Yuhe LI Tao 2013高电压技术2013,39,10:8

19Study on lightning risk assessment and early warning for UHV DC transmission channel显示文摘Operation data show lightning faults account for>70%for the main ultra-high voltage(UHV)DC transmission channels,very different from the design view.In order to accurately master the lightning characteristics and the lightning protection performance of the line so as to propose solutions to weak points,this study firstly obtains and analyses the density and strength distributions of lightning risk source.Then the study proposes a set of risk assessment process where the key model electrogeometric model is improved according to the polarity effect of DC line.Then the work realises the calculation of the lightning shielding failure risk of single tower and whole line.The example shows the assessment result is consistent to the line's actual operation.Next,to further evaluate and predict the lightning risk in real time,the study adopts the backpropagation neural network algorithm to integrate the lightning detection data,atmospheric electric fields,and radar echoes to develop the early warning model of lightning risk source,and proposed a method to realise the early warning of lightning damage risk for UHV DC channels.The results show that the effective warning ratio is 73%and the failure-to-warn ratio is 27%which indicates very good application effects.Shanqiang Gu Jian Wang Min Wu Juntian Guo Chun Zhao Jian Li 2019High Voltage2019,4,2:1
20The prognostic factors and nomogram for patients with high-grade gliomas显示文摘The evaluation on prognosis of glioma patients is critical for the individualized treatment.Despite of the widely used mRNA expression level and methylation status of prognostic genes in predicting the patients’prognosis,the clinical application of high-throughput sequencing technology is still limited.Thus,this study aimed to construct a visual and reliable nomogram based on the common clinicopathological parameters for predicting the prognosis of patients diagnosed with high grade glioma(HGG).Notably,age,histopathology,IDH status,1p/19q status,radiotherapy status,chemotherapy status,and tumor recurrence were identified as seven independent prognostic factors for HGG patients.A comprehensive nomogram based on the seven identified factors was subsequently constructed with the remarkable C-index of 0.732.Calibrations for nomogram showed great consistency between the predictive values and the actual values in 1-,3-,and 5-year survival rates.Besides,the areas under the ROC curve(AUC)for predicting 1-,3-,and 5-year survival rates of patients had the values of 0.796(95%CI:0.759-0.833),0.809(95%CI:0.770-0.848),and 0.820(95%CI:0.771-0.869),respectively.Furthermore,an external cohort(n=89)was used to validate the nomogram.In conclusion,age,histopathology,IDH status,1p/19q sta-tus,radiotherapy status,chemotherapy status,and tumor progression were identified as independent prognostic factors,on which a visual predictive model was constructed with powerful predictive value.Shanqiang Qu Ouwen Qiu Zhicheng Hu 2021Fundamental Research2021,1,6:0
