| 1 | Analytical Method of Fault Characteristic and Non-unit Protection for HVDC Transmission Lines显示文摘An analytical method of fault characteristic for the HVDC system based on frequency response characteristics of boundary elements is presented here.The computational formulas of transfer function and input impedance are deduced using the distributed parameter model of HVDC transmission line,and the amplitude-to-frequency-characteristics of the transfer function and input impedance are analyzed.Based on the amplitude-to-frequency difference between internal and external faults,a non-unit protection method for VSC-HVDC transmission line is presented.Using the current ratio of high-to-low-frequency,this protection method can distinguish internal from external fault.The presented algorithm only uses local-end current,has high operation speed,and is easy to implement.Simulations on a±200 kV VSC-HVDC system are conducted to demonstrate the validity and feasibility of the developed protection method. | Xu Chu Guobing Song Jun Liang | 2016 | CSEE Journal of Power and Energy Systems2016，2，4： | 10 |
| 2 | Impacts of Large-scale Wind Power Grid Integration on Relay Protection and Countermeasures显示文摘Several large-scale wind turbine tripping accidents occurred in Jiuquan wind power base in 2011.According to the on-site survey and analysis of these accidents related to relay protection,causes were found to be the collection system defects and low correct operation rate of small current grounded line selectors of the unearthed neutral point collection system.By referring to both the characteristics of Jiuquan wind power base and arrangement of relay protection,the short-circuit features of wind power and its impacts on relay protection are analyzed.The collection system and the retrofit of the small current grounded line selector are improved by specific countermeasures.Finally,further research subjects are put forward. | He, Shien Suonan, Jiale Kang, Xiaoning Song, Guobing | 2012 | 电力系统自动化2012，36，8： | 6 |
| 3 | Combined peripheral natural killer cell and circulating tumor cell enumeration enhance prognostic efficiency in patients with metastatic triple-negative breast cancer显示文摘Objective:Triple-negative breast cancer(TNBC)is a heterogeneous disease with poor prognosis.Circulating tumor cells(CTCs)are a promising predictor for breast cancer prognoses but their reliability regarding progression-free survival(PFS)is controversial.We aim to verify their predictive value in TNBC.Methods:In present prospective cohort study,we used the Pep@MNPs method to enumerate CTCs in baseline blood samples from 75 patients with TNBC(taken at inclusion in this study)and analyzed correlations between CTC numbers and outcomes and other clinical parameters.Results:Median PFS was 6.0(range:1.0–25.0)months for the entire cohort,in whom we found no correlations between baseline CTC status and initial tumor stage(P=0.167),tumor grade(P=0.783)or histological type(P=0.084).However,among those getting first-line treatment,baseline CTC status was positively correlated with ratio of peripheral natural killer(NK)cells(P=0.032),presence of lung metastasis(P=0.034)and number of visceral metastatic site(P=0.037).Baseline CTC status was predictive for PFS in first-line TNBC(P=0.033),but not for the cohort as a whole(P=0.118).This prognostic limitation of CTC could be ameliorated by combining CTC and NK cell enumeration(P=0.049).Conclusions:Baseline CTC status was predictive of lung metastasis,peripheral NK cell ratio and PFS in TNBC patients undergoing first-line treatment.We have developed a combined CTC-NK enumeration strategy that allows us to predict PFS in TNBC without any preconditions. | Xiaoran Liu Ran Ran Bin Shao Hope S.Rugo Yanlian Yang Zhiyuan Hu Zewen Wei Fengling Wan Weiyao Kong Guohong Song Hanfang Jiang Xu Liang Ruyan Zhang Ying Yan Guobing Xu Huiping Li | 2018 | Chinese Journal of Cancer Research2018，30，3： | 4 |
| 4 | Adaptive restarting method for LCC-HVDC based on principle of fault location by current injection显示文摘The existing LCC-HVDC transmission project adopts the fixed-time delay restarting method.This method has disadvantages such as non-selectivity,long restart process,and high probability of restart failure.These issues cause a secondary impact on equipment and system power fluctuation.To solve this problem,an adaptive restarting method based on the principle of fault location by current injection is proposed.First,an additional control strategy is proposed to inject a current detection signal.Second,the propagation law of the current signal in the line is analyzed based on the distributed parameter model of transmission line.Finally,a method for identifying fault properties based on the principle of fault location is proposed.The method fully considers the influence of the long-distance transmission line with earth capacitance and overcomes the influence of the increasing effect of the opposite terminal.Simulation results show that the proposed method can accurately identify the fault properties under various complex fault conditions and subsequently realize the adaptive restarting process. | Ruidong Xu Guobing Song Junjie Hou Zhongxue Chang | 2021 | Global Energy Interconnection2021，4，6： | 2 |
| 5 | Biomarkers of aging显示文摘Aging biomarkers are a combination of biological parameters to(i)assess age-related changes,(ii)track the physiological aging process,and(iii)predict the transition into a pathological status.Although a broad spectrum of aging biomarkers has been developed,their potential uses and limitations remain poorly characterized.An immediate goal of biomarkers is to help us answer the following three fundamental questions in aging research:How old are we?Why do we get old?And how can we age slower?This review aims to address this need.Here,we summarize our current knowledge of biomarkers developed for cellular,organ,and organismal levels of aging,comprising six pillars:physiological characteristics,medical imaging,histological features,cellular alterations,molecular changes,and secretory factors.To fulfill all these requisites,we propose that aging biomarkers should qualify for being specific,systemic,and clinically relevant. | Aging Biomarker Consortium Hainan Bao Jiani Cao Mengting Chen Min Chen Wei Chen Xiao Chen Yanhao Chen Yu Chen Yutian Chen Zhiyang Chen Jagadish K Chhetri Yingjie Ding Junlin Feng Jun Guo Mengmeng Guo Chuting He Yujuan Jia Haiping Jiang Ying Jing Dingfeng Li Jiaming Li Jingyi Li Qinhao Liang Rui Liang Feng Liu Xiaoqian Liu Zuojun Liu Oscar Junhong Luo Jianwei Lv Jingyi Ma Kehang Mao Jiawei Nie Xinhua Qiao Xinpei Sun Xiaoqiang Tang Jianfang Wang Qiaoran Wang Siyuan Wang Xuan Wang Yaning Wang Yuhan Wang Rimo Wu Kai Xia Fu-Hui Xiao Lingyan Xu Yingying Xu Haoteng Yan Liang Yang Ruici Yang Yuanxin Yang Yilin Ying Le Zhang Weiwei Zhang Wenwan Zhang Xing Zhang Zhuo Zhang Min Zhou Rui Zhou Qingchen Zhu Zhengmao Zhu Feng Cao Zhongwei Cao Piu Chan Chang Chen Guobing Chen Hou-Zao Chen Jun Chen Weimin Ci Bi-Sen Ding Qiurong Ding Feng Gao Jing-Dong JHan Kai Huang Zhenyu Ju Qing-Peng Kong Ji Li Jian Li Xin Li Baohua Liu Feng Liu Lin Liu Qiang Liu Qiang Liu Xingguo Liu Yong Liu Xianghang Luo Shuai Ma Xinran Ma Zhiyong Mao Jing Nie Yaojin Peng Jing Qu Jie Ren Ruibao Ren Moshi Song Zhou Songyang Yi Eve Sun Yu Sun Mei Tian Shusen Wang Si Wang Xia Wang Xiaoning Wang Yan-Jiang Wang Yunfang Wang Catherine CL Wong Andy Peng Xiang Yichuan Xiao Zhengwei Xie Daichao Xu Jing Ye Rui Yue Cuntai Zhang Hongbo Zhang Liang Zhang Weiqi Zhang Yong Zhang Yun-Wu Zhang Zhuohua Zhang Tongbiao Zhao Yuzheng Zhao Dahai Zhu Weiguo Zou Gang Pei Guang-Hui Liu | 2023 | Science China(Life Sciences)2023，66，5： | 2 |

| 8 | Dl-3-n butylphthalide attenuates brain injury caused by cortical infarction accompanied by cranial venous drainage disturbance显示文摘Background Cerebral venous disorder may have a harmful effect on ischaemic stroke;however,the underlying mechanism remains to be elucidated.Although Dl-3-n butylphthalide is a multitarget agent for antiischaemic stroke,its neuroprotective role in brain ischaemia accompanied by brain venous disturbance remains unclear.In this study,we induced cerebral venous disturbance by the occlusion of bilateral external jugular veins(EJVs)to explore the potential mechanism of the adverse effects of cerebrovenous disorders in cerebral infarction and explore the protective effect of Dl-3-n butylphthalide on cerebral infarction accompanied through cerebral venous disturbance.Methods Cerebral venous disturbance was induced in Sprague-Dawley rats through the permanent occlusion of bilateral EJVs,and cerebral ischaemic stroke was induced through the permanent occlusion of the right cortical branches of the middle cerebral artery.2,3,5-triphenyltetrazolium chloride staining,MRI,Evans blue extravasation and behavioural test were performed to evaluate infarction volume,cerebral blood flow(CBF),blood-brain barrier(BBB)integrity and neurological function.Immunofluorescence staining and western blot analysis were performed to detect loss of neuron,endothelial cells,pericytes and tight junctions.Results Bilateral EJVs occlusion did not cause cerebral infarction;however,it increased the infarction volume compared with the simple middle cerebral artery occlusion(MCAO)group,accompanied by severe neuron loss,worse neurological function,lower CBF,increased EJVs pressure,exacerbated Evans blue extravasation and brain oedema,as well as attenuated angiogenesis.Dl-3-n butylphthalide displayed a neuroprotective effect in rats with MCAO accompanied by EJVs occlusion by reducing neuron loss,accelerating CBF restoration,promoting angiogenesis and relieving BBB damage.Conclusion Bilateral EJVs occlusion did not significantly affect normal rats but aggravated brain damage in the case of ischaemic stroke.Dl-3-n butylphthalide treatment plays a neuroprotective role in rats with MCAO accompanied by EJVs occlusion,mainly due to the promotion of CBF restoration and BBB protection. | Kangping Song Xiuli Zeng Xiaomei Xie Rongxuan Zhu Jianye Liang Guobing Chen Li’an Huang | 2022 | Stroke & Vascular Neurology2022，7，3： | 1 |

| 14 | Pilot protection of hybrid MMC DC grid based on active detection显示文摘Considering the advantages and limitations of traditional identification method,combined with the strategy of active detection,the principle of DC grid pilot protection based on active detection is proposed to improve the sensitivity and reliability of hybrid MMC DC grid protection,and to ensure the accurate identification of fault areas in DC grid.By using the DC fault ride-through control strategy of the hybrid sub-module MMC,the fault current at the converter station DC terminal is limited.Based on the high controllability of hybrid MMC,sinusoidal fault detection signals with the same frequency are injected into the line at each converter station.Based on model recognition,the capacitance model condition is satisfied by the detected signals at both ends during external faults whereas not satisfied during internal faults.The Spearman correlation coefficients is then introduced,and the correlation discriminant of capacitance model is constructed to realize fault area discrimination of DC grid.The simulation results show that the active detection protection scheme proposed in this paper can accurately identify the fault area of DC grid,and is not affected by fault impedance and has low sampling rate requirement. | Guobing Song Junjie Hou Bing Guo Zhehong Chen | 2020 | Protection and Control of Modern Power Systems2020，5，1： | 1 |
