【网络强国这十年】当电表连上大数据,让“双碳”目标更近一步******

  【网络强国这十年——行业观点篇】

  如今,碳中和已在全球范围内达成共识。要实现碳中和,需要在各行业进行深度脱碳。随着大数据、人工智能等新技术的应用,电力行业也在积极革新,推动建设数字基础设施,助推电力行业“双碳”目标的实现。

  党的二十大报告提出,推动能源清洁低碳高效利用,推进工业、建筑、交通等领域清洁低碳转型。近年来,志翔科技围绕能源大数据生态,孵化了系列能源大数据产品,在电力企业得到广泛应用,有力支撑国家新型电力系统建设。近日,志翔科技总裁蒋天仪做客光明网“网络强国这十年”专栏,畅谈大数据如何助推电力行业智能化升级,支撑行业碳计量的精准化,为“碳达峰、碳中和”目标实施奠定基础条件。

【网络强国这十年】当电表连上大数据,让“双碳”目标更近一步

  传统电网的电力数据来源分散、结构多样、质量参差不齐;基于这样的数据很难提供全面精准的数据服务。万物互联时代,数据采集的手段和数据的质量都有了飞跃。充分进行数据采集和处理分析并指导业务,是保障大规模新能源并网和消纳的基本条件之一。蒋天仪认为“精细化”的数据运营管理和计量是关键。

  在目前电力行业有一个“三可”的说法(可观:客观采集获取用电数据、可测:精准监测和测量、可控:在可观可测的基础上按需控制),蒋天仪认为,其实在三可的基础上,还可增加“可调”。他介绍,通过大数据分析,目前已经基本达到“可观可测”,这也是“可控”的前提条件。那么,如何让调控更加科学有效?就需要更加精细化的调节调度,即“可调”。

  为此,志翔科技研发了非介入式负荷分析产品。通过在新一代智能物联网表上安装边缘计算模块,利用电力指纹技术可以提供精准的用电设备负荷、能耗、使用状况等信息的侦知和分析。电力公司利用非介入式负荷分析产品,可以更精准辨识户内负荷,输出相应用电设备的能耗详单,为用电高峰期制定错峰用电方案提供有力数据支撑。

  “过去,我们通过电表只是知道这一户用了多少电,不清楚具体有什么设备在用。但安装非介入式负荷辨识产品模块之后,电力企业可以更加精细地掌握用电情况。”蒋天仪说。

  记者了解到,除了工业企业生产和用户生活的用电负荷精细化管理之外,在各行各业、日常生活等场景下,通过大数据对用电设备负荷、能耗等的详细分析也很有想象空间。比如,在消防安全管理方面,通过监测和分析用户用电情况,可以有效检测两轮电动车入户充电等消防隐患行为,从而有效避免火灾问题。在物业管理和环保用电方面,按规定商业楼宇内夜间严禁住人,传统的办法是安排人为巡检,如今非介入式负荷分析产品就能替代人工进行自动分析和监测等。

  “随着信息化技术的发展,大数据、云计算等带来的数据量越来越大,很多以前没有利用起来的零散数据,随着大数据技术的成熟和应用,可以通过关联和深度分析而产生价值。”蒋天仪认为,目前,国家已经出台了《数据安全法》《个人信息保护法》等法律法规,为数据安全行业和百姓个人隐私保驾护航。另一方面,大数据在工业领域的应用,尚处于起步阶段,未来还有很大发展空间,需要更多有技术能力的厂商积极创新,让产品更好地落地和应用服务于各行各业,在企业生产效率提升、百姓生活便利的多个方面发挥更大价值。

中新网评:处理核污水绝不是日本自家私事******

  中新网北京1月19日电(蒋鲤)日本政府近日称,将于2023年春夏期间开始向海洋排放经过处理的福岛第一核电站核污水。日本罔顾国内民众及周边国家的屡屡反对,企图将核污水“一倒了之”,把一件关乎全球海洋生态环境和公众健康的事当成了自家私事。

  2011年,福岛核电站事故发生后,大量放射性物质泄漏到大气层和太平洋,对周围环境造成了难以逆转的伤害,数十万人被迫撤离该地区。时至今日,作为日本邻国之一的韩国仍未解除福岛海鲜禁令。

  日本以核污水存储能力即将达到上限为由,在2021年4月13日,正式决定将福岛第一核电站核污水排入太平洋。过去一年多,日本政府和东京电力公司一直在持续推进核污水排海计划。

  日本政府辩称,这些核污水经多核素处理系统(ALPS)处理后很安全,甚至“可以喝”,这样的表态无疑在愚弄大众。

  事实上,经过处理的核污水仍含有多种放射性物质,核污水一旦排放入海就无法回收,长期来看,将会给海洋生态带来难以估量的潜在威胁,最终危害人类健康。

  因此,核污水排海计划推出后,遭到日本民众强烈反对。日本《朝日新闻》2022年3月公布的问卷调查显示,福岛县、宫城县和岩手县受访的42个市町村长中,约六成反对东京电力公司福岛第一核电站核污水排放入海。日本全国渔业协会联合会也多次申明立场,反对该计划。

  日本政府认为,核污水排海是最便宜、最省事的解决方案,但此举却将周边国家乃至全世界置于核污染风险中。太平洋非日本一家之海,核污水会随着洋流流动,其影响势必会跨越国界,危害周边国家乃至整个国际社会的公共福祉和利益。

  《韩国经济新闻》发文称,相关研究认为,福岛核污水如果排放入海,约7个月后将到达济州等韩国海域,该国水产业和旅游业将遭受相当大的损失。

  德国南极海洋机构也曾发出警告,若日本将所有核污水排入海中,不到半年,整个太平洋都将面临高度辐射威胁,包括远在大洋另一端的美国。太平洋地区人民更是对日本该计划持反对意见。

  日本作为《联合国海洋法公约》缔约国,有义务保护海洋环境。然而,在核污水排海方案的正当性、核污水数据的可靠性、净化装置的有效性、环境影响的不确定性等问题上,日本未能作出科学、可信的说明。

  国际原子能机构技术工作组虽已三次赴日实地考察评估,但尚未就日排海方案的安全性给出结论,并且对日本提出诸多澄清要求和整改意见。在此情况下,日本仍执意推进核污水排海工程建设,这是极不负责任的行为。

  太平洋不是日本的下水道,日本必须正视各方合理关切,在与周边国家等相关利益方和国际原子能机构充分协商后,制定合理的核污水处理方案。日本也要着眼长远,若只顾眼前,执意将核污水排放入海,不仅其自身,周边国家乃至全世界都将为之买单,其后果必将会危害数代人。

  Fukushima water disposal by no means Japan’s own business

  By John Lee

  (ECNS) -- Japan has announced it will release treated wastewater from the wrecked Fukushima Daiichi Nuclear Power Plant into the Pacific Ocean this year.

  Although Fukushima wastewater disposal affects global marine ecological environment protection and public health, Japan has turned a deaf ear to domestic and international opposition to dumping the contaminated water into the sea, treating the "global" matter as its own business.

  The Fukushima accident in 2011 had sent large quantities of radiation into the atmosphere and the Pacific Ocean, causing irreversible damage to the surrounding environment, and hundreds of thousands of people were forced to evacuate the area. South Korea still maintains its import ban on Japanese seafood from areas affected by the Fukushima nuclear disaster.

  On April 13, 2021, Japan announced it had decided to discharge contaminated radioactive wastewater in Fukushima Prefecture into the sea due to dwindling storage space, with the Japanese government and plant operator Tokyo Electric Power Company Holdings Inc. promoting the release plan over the past year.

  The Japanese government argues that the water treated by an advanced liquid processing system, or ALPS, is safe and drinkable, which is undoubtedly fooling the public.

  In fact, the treated wastewater still includes a variety of radioactive substances and can’t be recycled once discharged into the sea, which will pose a great threat to marine ecology and ultimately endanger human health in the long run.

  Therefore, the discharge plan has been strongly opposed in Japan. According to a questionnaire conducted by The Asahi Shimbun, nearly 60 percent of mayors of 42 municipalities in Iwate, Miyagi and Fukushima prefectures oppose the discharge plan. The National Fisheries Cooperative Federation of Japan has also repeatedly stated its opposition in public.

  The Japanese government believes that dumping Fukushima wastewater into the sea is the cheapest and most convenient solution, but neighboring countries and even the whole world will be at risk of nuclear pollution.

  The Pacific Ocean doesn’t belong to Japan and the wastewater flow along oceanic currents will surely break boundaries and endanger public welfare and the interests of neighboring countries and even the international community.

  The Korea Economic Daily reported that related research concluded that if contaminated water from Fukushima is released into the ocean, it would only take seven months for the contaminated water to reach the shores of Jeju Island, with the country's aquaculture and tourism suffering considerable losses.

  According to the calculation of a German marine scientific research institute, radioactive materials will spread to most of the Pacific Ocean within half a year from the date of discharge, and the U.S. and Canada will be affected by nuclear pollution. People in the Pacific region also oppose the discharge plan.

  As a participant of the United Nations Convention on the Law of the Sea, Japan has the obligation of protecting the marine environment.

  However, it hasn’t offered a full and convincing explanation on issues like the legitimacy of the discharge plan, the reliability of data on the nuclear-contaminated water, the efficacy of the treatment system or the uncertainty of environmental impact.

  Though the IAEA has yet to complete a comprehensive review after three investigations in Japan, the Japanese side has been pushing through the approval process for its discharge plan and even started building facilities for the discharge. It is rather irresponsible for Japan to act against public opinion at home and concerns abroad.

  The Pacific Ocean is not a private Japanese sewer. The country must seriously heed the voices of the international community and make a reasonable plan for the Fukushima wastewater disposal after full consultation with stakeholders and international agencies.

  If it only seeks instant interest and insists on discharging the contaminated water into the sea, not only itself, but also its neighboring countries and the entire world will pay for the decision and several generations will be forced to bear the consequence.
