Publication number: 20240133975Abstract: A computerized simulation validating method for a full-scale distribution network single phase-to-ground fault test is implemented by simulating a full-scale test system with external quantities being controlled to be conformant and validating the full-scale distribution network single phase-to-ground fault test based on a conformance check result between the internal quantities of the field testing and the internal quantities of the simulation testing. The simulation validating method for a full-scale distribution network single phase-to-ground fault test improves normalization and conformance of the full-scale distribution network ground fault test. The computerized simulation validating system, apparatus, and medium for a full-scale distribution network single phase-to-ground fault test also achieve the benefits noted above.Type: ApplicationFiled: August 10, 2023Publication date: April 25, 2024Inventors: Zhi LI, Shaofeng YU, Dingfang KE, Peibo WANG, Kan SUN, Weiqiang LANG, Haijiang XU, Kelong WANG, Zhiyong LI, Kun YU, Guangyao YING, Xuqiang HE, Yezhao CHEN, Xiang ZHANG, Mingxiao DU, Huijuan GUI, Hongling HU, Biao PENG, Xubin XIAO

Patent number: 9457388Abstract: The present invention involves a persulfate-release material used in the filler of permeable reactive barrier (PRB). This material presents double-layered structure characteristic: inner- and outer-layers are consisted of persulfate, cement, sand and water with different mass ratio. Two different types of moulds are used for the regulation of the shape of the two-layer structures, which guarantees the stability and reproducibility of its structures and properties. During the whole released process, the released rate become more uniform and stable by the use of this material. During the whole service period, the change of the released rate is very slow, and the service lifetime can be 1-10 years. This invention can both reduce the initial released rate and improve the later released rate, and thus the whole released rate can be more uniform, which can be an important method to promote the efficiency of the persulfate toward engineering application.Type: GrantFiled: July 18, 2014Date of Patent: October 4, 2016Assignee: CHINESE RESEARCH ACADEMY OF ENVIRONMENTAL SCIENCESInventors: Beidou Xi, Yonghai Jiang, Yu Yang, Mingxiao Li, Zhifei Ma, Lieyu Zhang, Min Li, Fangyi Chen
