Aiming at the construction and development of highway noise barrier engineering in China, the survey analyzed the types of highway noise barriers, summarized and analyzed the problems in the application of highway noise barriers, and discussed the construction concept and development status of highway noise barriers. The research results show that: the highway noise barrier gradually develops from simple upright type plate concrete slab type to metal composite type, block type, transparent plate type, ecological type, and fully enclosed noise barrier, etc., and the selection and application of materials and structures are constantly enriched. During the implementation of the current highway noise barrier project, there are a few problems on difficult to meet the noise reduction requirements, gaps exist at the seal, damage to the natural landscape along the highway, the existence of shedding safety hazards, lack of post maintenance, etc. In recent years, China's highway noise barrier has changed to the direction of material diversification, type diversification, environment friendliness and maintenance simplicity, from material green and low-carbon, structure form landscape natural integration, assembly construction and maintenance, and the introduction of active noise control technology, which can provide new technology for China's highway noise barrier and highway traffic noise abatement. © 2023 Proceedings of the International Congress on Sound and Vibration.

Magnetic flux leakage, as a basic physical parameter in power transformer, can be utilized to characterize the status of the winding. And the DC biasing, as a common abnormal operation condition, is caused by solar storms, DC power transmission and some railway power transmission. It can induce the current bias and the core saturation, further changing the distribution of the magnetic flux leakage. Therefore, it is significant and valuable to analyze the effect of DC biasing on spatial magnetic leakage flux. In the paper, we design a transformer finite element model with its physical fieldcircuit simulation module. The model with some detailed winding structure can obtain the accurate magnetic field signal. Then the effect of different degrees DC biasing on the magnetic leakage flux is analyzed in the inner key positions. And the 10kV shrunken experimental transformer imitating the 110 k V transformer is selected as the research object. Depending on the experimental platform, we obtain the actual magnetic field signals and explore the incidence relation between the magnetic leakage flux and the DC biasing. © 2022 IEEE.

Transport, transformation, and ecological impacts of brominated flame retardants in soils: A comprehensive review

引用

Environmental Chemistry and Ecotoxicology 2025年 7卷 1142-1157页

作者： Jia Zhang Dan Li Ying Yuan Kunlong Hui Wenbing Tan State Key Laboratory of Environmental Criteria and Risk Assessment State Environmental Protection Key Laboratory of Simulation and Control of Groundwater Pollution Chinese Research Academy of Environmental Sciences Beijing 100012 China

Brominated flame retardants (BFRs) have become significant contaminants of emerging concern (CECs), resulting in detrimental effects on soil health, human health, and ecosystem sustainability. Their environmental impacts have spurred extensive research into environmental chemistry and ecotoxicology. Despite the widespread detection of both BFRs and Novel Brominated Flame Retardants (NBFRs) in soils, there are few assessments of the environmental behavior and fate of the BFRs. Therefore, this review comprehensively identifies the sources, distribution, transport, transformation, ecotoxicological effects, and remediation strategies of BFRs in soils. Principal findings indicate that adsorption-desorption, mostly influenced by soil organic matter, controls the mobility and transformation of BFRs. Photolysis dominates surface soils, while aerobic and anaerobic biodegradation predominate in subsurface layers. The main factors influencing the bioavailability of BFRs are shed light on in this review. These factors such as the physicochemical properties of BFRs, soil characteristics, and combined pollution are specifically discussed. Moreover, the development, physiological, and biochemical responses of soil organisms to exposure to the BFRs are summarized. Single strategies for addressing BFRs have certain limitations. Urgent actions are needed to focus on environmental behavior and remediation strategies under the “One Health” framework to enrich research gap areas of BFRs, NBFRs, and transformation products.

Transmission Line Distance protection Under Current Transformer Saturation

Conventional transmission line distance protection approaches are subject to malfunction under reverse fault-induced current transformer(CT) saturation for the typically employed breaker-and-a-half configuration. This paper addresses this issue by proposing a new distance protection approach that combines the blocking and unblocking criteria of distance protection based on the values of incomplete differential current,operation voltage, and current harmonic content. The proposed approach is verified by theoretical analysis, dynamic simulation testing, and field operation to ensure that the obtained distance protection is reliable and refrains from operating unnecessarily under reverse fault-induced CT saturation in the breaker-and-ahalf configuration. Meanwhile, the proposed approach is demonstrated can operate reliably when forward faults occur or various reverse faults are converted to forward faults.

作者： Lin Bo Taishan Xu Mengfu Tu Jinjun Lu NARI Group Co. Ltd.(State Key Laboratory of Smart Grid Protection and Control) Nanjing Chinas

The volatility and uncertainty of wind power bring severe challenges to the power system, and the modeling of multi-wind farm output scenarios considering the uncertainty of wind power is of great significance in power system dispatching decision-making. Especially for area/ province with abundant wind power resources, where the reliability of the dispatching plan can be strongly affected by the volatility of large amount of wind power. In this paper, a practical method of generating probabilistic scenarios for day-ahead wind power output is proposed for provincial power grid with high proportion of wind power. Firstly, the K-Shape clustering algorithm is used to cluster the wind farm stations, and then the output scenario are generated by using the total wind power forecast value and forecast error probability distribution characteristics of each aggregated station. After arrangement and combination of the aggregated stations’ scenes, the scenario minimization based on probability distance was conducted for clustering reduction to obtain the typical output scenes, and then the typical output scenes were assigned to each station according to the forecast value of the station to obtain the probability output scenes of each station. It is verified by actual power grid data that the scenarios generated by this method can combine with wind power predictions to well depict the random fluctuation of multi-wind farms output and has a good application prospect in the practice of day-ahead dispatching decision making.
