通过近地面机载观测不仅能够精准稳定获取空间信息，而且能够弥补野外站点观测在空间连续性、区域一致性以及观测精度上的不足，解决卫星遥感时空分辨率过低以及与地面监测校准尺度不匹配的问题，成为温室气体监测的一项重要辅助手段。煤炭作为我国的主体能源、重要的工业原料是保障能源安全稳定供应的基石。“双碳” 背景下，在巩固煤炭兜底保障作用的同时促进煤炭清洁高效利用，构建智能装备与现代煤炭开发的深度融合，对于我国煤炭产业可持续发展至关重要中煤电气有限公司作为中煤集团全资子公司是目前全国煤炭系统产品业务0广、涉及领域0多的综合电气自动化企业之一，在“双碳”长期目标指引下，以科技为依托，专注于推动煤炭行业与新能源耦合发展，为煤炭行业智能化、数字化转型持续贡献中煤力量。近日，ABB为中煤大屯电厂及大屯姚桥煤矿提供iVD4中压智能化解决方案，助力其实现从“人控”到“数控”运维的全面升级提速，加速迈进智能化时代。

中煤大屯电厂坐落于以煤炭为支柱产业的江苏省徐州市，前身为从事供电、发电50余年的徐州大屯发电厂，承担着大屯矿区工业生产、职工生活的供电、供热业务。该发电厂远距城市中心数十公里，运维人员流动率高且招工困难。早期，电厂采用人海战术“24小时三班倒”（每个开闭所配置多人，每8小时轮班），不仅导致非专业人员“臃肿”，还易发生运维漏检、错检等不足，在实际运行中存在巨大的安全隐患。ABB以中煤大屯电厂安全可靠的运营需求和绿色发展规划为核心，为其提供iVD4®中压开关智能化解决方案，在帮助电厂降低运维成本的同时帮助其提高全生命周期稳定、持续运行。项目中采用的VD4中压真空断路器和ConVac中压真空接触器的智能化解决方案具有丰富的数字化监测与诊断功能，可根据不同的配电回路情况实时监控设备运行状况，使配电室实现对分散配电系统参量的全面监控，帮助运维人员快速锁定故障点，提前发现设备隐患，保障供电稳定性和连续性。不止于智能化的解决方案，iVD4中压真空断路器更是绿色环保的利器。作为通过中国环境标志(Ⅱ型)认证和碳足迹双重认证产品，ABB VD4真空断路器采用创新的环保型绝缘材料(PT极柱)，告别三废污染(废水、废气和固体废弃物)，是绿色电气化的可持续推动者，有效帮助发电厂节能减排，实现绿色低碳发展目标。
Near ground airborne observation can not only accurately and stably obtain spatial information, but also make up for the deficiencies of field site observation in spatial continuity, regional consistency and observation accuracy, solve the problems of low spatial and temporal resolution of satellite remote sensing and mismatch with calibration scale of ground monitoring, and become an important auxiliary means of greenhouse gas monitoring. As the main energy and important industrial raw materials in China, coal is the cornerstone to ensure the safe and stable supply of energy. Under the background of "dual carbon", it is crucial for the sustainable development of China's coal industry that China Coal Electric Co., Ltd., as a wholly-owned subsidiary of China Coal Group, promotes the clean and efficient use of coal while consolidating the role of coal as a guarantee, and builds a deep integration of intelligent equipment and modern coal development. At present, China Coal Electric Co., Ltd. is one of the comprehensive electrical automation enterprises with the broadest business and the most involved fields of coal system products in China, Under the guidance of the long-term goal of "double carbon", relying on science and technology, it focuses on promoting the coupling development of the coal industry and new energy, and continuously contributes to the intelligent and digital transformation of the coal industry. Recently, ABB has provided iVD4 medium voltage intelligent solutions for China Coal Datun Power Plant and Datun Yaoqiao Coal Mine, helping them achieve comprehensive upgrading and speed up from "human control" to "numerical control" operation and maintenance, and accelerating into an intelligent era.



China Coal Datun Power Plant is located in Xuzhou City, Jiangsu Province, where coal is the pillar industry. Its predecessor is Xuzhou Datun Power Plant, which has been engaged in power supply and power generation for more than 50 years. It undertakes the power supply and heat supply business of industrial production and staff life in Datun mining area. The power plant is tens of kilometers away from the city center, with high turnover rate of operation and maintenance personnel and difficult recruitment. In the early days, the power plant adopted the "three shifts every 24 hours" strategy (more people for each sub section post, and shifts every 8 hours), which not only led to "overstaffing" of non professionals, but also led to deficiencies such as missed inspection and wrong inspection in operation and maintenance, and there were huge potential safety hazards in actual operation. ABB focuses on the safe and reliable operation demand and green development plan of China Coal Datun Power Plant to provide it with iVD4 ® The intelligent solution of medium voltage switch can help the power plant to reduce the operation and maintenance cost and improve its stable and continuous operation throughout its life cycle. The intelligent solution of VD4 medium voltage vacuum circuit breaker and ConVac medium voltage vacuum contactor adopted in the project has rich digital monitoring and diagnosis functions, which can monitor the operation status of equipment in real time according to different distribution circuit conditions, enable the distribution room to achieve comprehensive monitoring of distributed distribution system parameters, help the operation and maintenance personnel to quickly lock the fault point, find the hidden danger of equipment in advance, and ensure the stability and continuity of power supply. More than intelligent solutions, the iVD4 medium voltage vacuum circuit breaker is a green and environment-friendly weapon. As a product that has passed the certification of China's environmental label (Type II) and the double certification of carbon footprint, ABB VD4 vacuum circuit breaker uses innovative environment-friendly insulating materials (PT poles) to bid farewell to the three wastes pollution (waste water, waste gas and solid waste). It is a sustainable promoter of green electrification, effectively helping power plants save energy and reduce emissions, and achieving the goal of green and low-carbon development.
