| 1 | An innovative integrated system utilizing solar energy as power for the treatment of decentralized wastewater显示文摘This article reports an innovative integrated system utilizing solar energy as power for decentralized wastewater treatment, which consists of an oxidation ditch with double channels and a photovoltaic (PV) system without a storage battery. Because the system operates without a storage battery, which can reduce the cost of the PV system, the solar radiation intensity affects the amount of power output from the PV system. To ensure that the power output is sufficient in all different weather conditions, the solar radiation intensity of 78 W/m 2 with 95% confidence interval was defined as a threshold of power output for the PV system according to the monitoring results in this study, and a step power output mode was used to utilize the solar energy as well as possible. The oxidation ditch driven by the PV system without storage battery ran during the day and stopped at night. Therefore, anaerobic, anoxic and aerobic conditions could periodically appear in the oxidation ditch, which was favorable to nitrogen and phosphate removal from the wastewater. The experimental results showed that the system was efficient, achieving average removal efficiencies of 88% COD, 98% NH 4 + -N, 70% TN and 83% TP, under the loading rates of 140 mg COD/(g MLSS·day), 32 mg NH 4 + -N/(g MLSS·day), 44 mg TN/(g MLSS·day) and 5 mg TP/(g MLSS·day). | Changfu Han Junxin Liu Hanwen Liang Xuesong Guo Lin Li | 2013 | Journal of Environmental Sciences2013，25，2： | 12 |

| 6 | Study on lightning protection scheme of multi-terminal MMC-MVDC distribution system显示文摘Based on a±10 kV three-terminal MMC-MVDC(medium voltage DC distribution system based on modular multilevel converter)system,in this study,the authors mainly study on the influencing factors and protection schemes of the lightning intruding overvoltage(including direct lightning and back-flashover lightning).Firstly,a lightning intruding overvoltage simulation model of the MMC-MVDC distribution system using overhead lines is established based on the PSCAD/EMTDC program.The influence of steady-state operating voltage and the number of converter stations on the simulation results are simulated and analysed.Meanwhile,the proper simulation modelling method of the lightning intruding overvoltage for multi-terminal MMC-MVDC system is proposed.Secondly,the lightning intruding overvoltage is simulated when the line is struck by the lightning stroke current that occurs once in 20 years and the different lightning protection schemes are proposed.Finally,based on the lightning impulse withstand voltage,lightning trip-out rate and the cost of the protection schemes,the lightning protection schemes in different scenarios are proposed.The simulation results show that if the cost of the system is prioritised,the protection scheme of increasing the number of parallel stacks of the DL arresters can be selected,and if the power supply reliability of the system is prioritised,the protection scheme of installing the overhead ground wire as well as reducing grounding resistance can be selected. | Yuqun Gao Yongxia Han Fanglei Xiao Changfu Chen Jinghan Zhang Jie Zhang Yaqi Zhang Licheng Li | 2020 | High Voltage2020，5，5： | 1 |
