| 1 | Euphoractone,a cytotoxic meroterpenoid with an unusual entabietane-phloroglucinol skeleton,from Euphorbia fischeriana Steud.显示文摘A novel meroterpenoid,euphoractone(1),was isolated from the extracts of the roots of Euphorbia fischeriana Steud.Its structure was determined by spectroscopic methods and X-ray crystallography.1 possesses an unusual ent-abietane-phloroglucinol skeleton.The plausible biosynthetic pathway for 1 was proposed.1 showed inhibitory activities against human lung cancer H23 and H460 cells with the IC_(50)values of 21.07±3.54 and 20.91±4.07 μmol/L. | Rihan Xie Linsheng Li Xiaona Fan Jiachen Zi | 2020 | Chinese Chemical Letters2020，31，2： | 3 |

| 17 | A novel method for locating the source of sustained oscillation in power system using synchrophasors data显示文摘Large interconnected power systems are usually subjected to natural oscillation(NO)and forced oscillation(FO).NO occurs due to system transient response and is characterized by several oscillation modes,while FO occurs due to external perturbations driving generation sources.Compared to NO,FO is considered a more severe threat to the safe and reliable operation of power systems.Therefore,it is important to locate the source of FO so corrective actions can be taken to ensure stable power system operation.In this paper,a novel approach based on two-step signal processing is proposed to characterize FO in terms of its frequency components,duration,nature,and the location of the source.Data recorded by the Phasor Measurement Units(PMUs)in a Wide Area Monitoring System(WAMS)is utilized for analysis.As PMU data usually contains white noise and appears as multi-frequency oscillatory signal,the first step is to de-noise the raw PMU data by decomposing it into a series of intrinsic mode functions(IMF)using Improved Complete Ensemble Empirical Mode Decomposition with Adaptive Noise(ICEEMDAN)technique.The most appropriate IMF containing the vital information is selected using the correlation technique.The second step involves various signal processing and statistical analysis tools such as segmented Power Spectrum Density(PSD),excess kurtosis,cross PSD etc.to achieve the desired objectives.The analysis performed on the simulated two-area four-machine system,reduced WECC-179 bus 29 machine system,and the real-time power system PMU data set from ISO New England,demonstrates the accuracy of the proposed method.The proposed approach is independent of complex network topologies and their characteristics,and is also robust against measurement noise usually contained in PMU data. | Mohd Zuhaib Mohd Rihan Mohd Tayyab Saeed | 2020 | Protection and Control of Modern Power Systems2020，5，1： | 1 |
