中国新歌声直面“白海豚”返场“加时大考”，筑牢杭城防汛“水文防线”_我的网站
A | 今年8月9日，第13号台风“白海豚”在浙江省玉环市沿海登陆，带来狂风骤雨，初登陆后其残余云系并未消散，反而在大气环流影响下迅速掉头“返场”，长时间滞留并持续释放强降雨，给杭州防汛带来严峻考验。面对这场路径罕见，风雨极端的台风，杭州水文系统高度重视，树牢底线思维和极限思维，全员在岗迎战。 (ECNS) -- Installed distributed photovoltaic (PV) capacity in Ningbo, Zhejiang Province, surpassed 10 gigawatts (10,000 MW) on Wednesday, making it the first city in China to reach the 10-GW milestone for distributed PV. As a major industrial and power-consuming city, Ningbo is accelerating its transition toward greener, low-carbon energy. Most of the city’s distributed PV systems are installed on rooftops, with industrial parks accounting for 84% of the total capacity. Mi Haiting, an official with the Ningbo Energy Big Data Management Center, said that based on an annual equivalent full-load generation time of 1,000 hours, the city’s distributed PV facilities can generate 10 billion kWh of clean electricity each year, reducing carbon dioxide emissions by around 5 million metric tons — equivalent to planting roughly 120 million trees. Mi noted that solar power generation can fluctuate sharply over short periods, creating new challenges such as reverse power flows and overloads in distribution networks, mismatches between power supply and demand during peak and off-peak hours, and more complex energy settlement within industrial parks. Feng Yibin, head of the Technical Innovation Office of State Grid Zhejiang Electric Power Co., Ltd., said the city has developed a county-level, multi-factor grid planning and simulation platform, supported by Ningbo’s Digital-Physical Hybrid Simulation Laboratory for the new-type power system, to address these challenges. A distributed PV operation monitoring application has also been launched locally. (By Helen Mo, intern Xu Wenda)
B | 在此基础上，全面做好2780个监测站点运维管理，强化设备巡检维护，确保监测站数据畅通率99.8%以上，为调度提供一手情报。
C | 台风强降雨期间，依托瓶窑、长乐、潘板、余杭等站点洪水智能预报模型，逐小时滚动开展东苕溪干流洪水预报，支撑流域一体化调度。
D | 基于省山洪四预平台实现山洪高级别预警智能叫应，平台自动向属地水利部门、乡镇责任人发送浙政钉消息提醒，对未及时查收消息的责任人自动触发电话叫应，辅以人工电话叫应兜底，确保山洪预警直达基层一线防御责任人。本轮台风防御期间，累计发送预警短信11777条，发布洪水预警7期、山洪预警7期、洪水预报80余站次、杭州水情简报12期。面对“白海豚”的极限考验，市水文中心始终以“时时放心不下”的责任感和“事事准备周全”的行动力，持续筑牢杭城防汛防线，让这条防线经得起每一次风雨检验。 Current article:http://gxlpezm.shuicengchongmingnouhuawang.bond/1d5/20260826/5657.html Published on:12:28:14 |
。通过密切监视台风发展动态、滚动会商研判最新水雨情形势，全力以赴打好防汛防台主动仗。强化责任落实，压紧压实防汛重担市水文中心闻“风”而动、向“雨”而行，迅速启动应急响应机制，班子带头扛责在肩，充分发挥数据保障组、情报预报组和应急监测组的尖兵前哨作用，连续奋战14个日夜，强化“指挥中心+水情中心+一线测站”3地24小时值守，密切跟踪水雨情监测数据，实时分析河道水位、流量变化，确保信息报送及时准确。同时，中心抽调专业技术骨干，出动146人次深入运河流域和苕溪流域一线，开展河道流量、流速等关键数据监测，共计测流220测次，掌握第一手水文动态。
运河流域流量监测坚持流域“一盘棋”，精准开展洪水预报瓶窑水文站位于杭州北部东苕溪流域，作为站立在杭城“北大门”的国家重要水文站，肩负重要使命。瓶窑站水位高低直接关系着洪水是否会漫过西险大塘危及杭州主城，8月14日晚8时左右，苕溪流域瓶窑站水位追平27年前，即1999年7月1日的最高洪水位，随着暴雨不断落下，瓶窑水位继续上涨，15日凌晨2点半，瓶窑站洪峰水位来到了7.69米，新的纪录就此诞生。在此过程中，市水文中心牢固树立大局观念，做好东苕溪水位超历史极值的最充分准备，坚持上下游“一盘棋”，主动对接气象、水库、流域等上下游部门，开展雨情、水情、工情“即时会商”30余次，滚动开展洪水预报80余站次，杭州水情简报12期，为水涛庄、四岭水库错峰泄洪、北湖滞洪削峰提供精准决策依据。
会商研判多维攻坚破局，提升预报预警水平台风来临前，统筹运用苕溪、运河、分水江流域数字孪生平台、杭州市水旱灾害监测预警平台等，通过正反算相结合的方式，针对不同量级极端降雨，分流域提前预演5套洪水预报方案，并结合气象未来降雨预报滚动更新预报结果。
