什么是高压直流输电?

High-voltage direct current (HVDC) energy transmission is a time-tested technology that transmits power over long distances more efficiently than alternating current (AC) transmission. 除了, 高压直流输电不会产生与交流输电相关的有争议的电磁场.

项目路线是什么?

项目路线经过精心设计,占地面积最小, using waterways and existing rights of way to remain out of sight and avoid environmentally sensitive areas such as the PCB cleanup site in the upper Hudson River. 该项目将从美国运营.S.-加拿大边境, 向南穿过尚普兰湖, 哈德逊河沿岸和河底, 最终到达皇后区阿斯托里亚的一个换流站.

请看路线地图.

这个项目会对环境产生怎样的影响?

因为固态电缆的直径只有5英寸, 可以沿着现有的路权在水下和地下运行它们, 尽量减少对环境的干扰,并保留自然景观. 天博APP非常注意避开环境敏感的地点, 比如哈德逊河的多氯联苯浓度.

电缆将如何安装?

The cable will be installed using low-impact water jet technology that minimally impacts the environment. 请查看如何安装电缆的演示视频:

 

这个项目会在纽约使用架空输电吗?

No. 该电缆将铺设在现有的水道中或埋在地下. 将不会有新的架空传输与该项目有关.

如果电线被切断或损坏,水会带电吗?

如果线缆损坏, HVDC protection reduces the current and voltage to zero in a fraction of a second so t在这里 is no possibility of damage to persons, 鱼或附近的任何基础设施.

电缆一旦下水,将采取什么预防措施来保护它? 船上的锚能钩住它吗?

防止锚或钓鱼设备损坏缆绳, 这条线位于水道底部以下, 要么被淹没在河床/湖底,要么被屏障覆盖以防止被钩住. 在极不可能的情况下电缆被卡住了, the sheer weight of the cable will inform the vessel that they’ve attached to a major subsurface object. The cable itself incorporates fiber optic thermal and communication protection features that would detect any snag, as well as fault protection equipment at both converter stations to clear any fault nearly instantaneously. These safety features will shut down operations immediately should the cable become damaged in order to protect both life and equipment.

谁为这个项目提供资金?

该项目将100%由私人出资. TDI的主要发起人和股权提供者是黑石集团(Blackstone Group). The construction debt financing will come from a consortium of commercial banks and other private debt providers.

如果有超限怎么办? 这些会转嫁到纳税人身上吗?

作为一个私人项目,任何成本超支都将由项目的私人业主承担. 纳税人不会受到建设成本超支的影响.

这种新的力量从何而来?

TDI designed this project to meet the growing demands of the 纽约 marketplace by bringing new sources of clean, 负担得起的, 向消费者提供可天博app. 这种能源的来源将是可天博app发电机.

电力到哪里去了?

电力将被输送到一个将在皇后区阿斯托里亚建造的换流站, 纽约, 并将接入联合爱迪生电网.

政府批准这个项目了吗? 需要哪些批准?

该项目已获得联邦和州的所有必要许可, and we will work with applicable agencies on any permit modifications required to protect the environment. 有关许可的更多信息请访问 可以在这里.

这个项目会影响哈德逊河的PCB清理吗?

No. To avoid installing the HVDC cables within areas associated with the Hudson River PCB Dredging Project, 高压直流电缆路线将在尚普兰运河前退出,并遵循街道和铁路的通行权. 线路将埋在整个地区,以避免架空输电对视觉的影响.

以前有人做过这种类型的项目吗? 把电缆埋在水下安全吗?

埋地高压直流电缆(HVDC)已经在世界范围内使用了近80年. 高压直流输电线路最早的一些商业用途可以追溯到20世纪50年代初, 其中许多至今仍在服役. These include projects such as the Neptune project which safely connects New Jersey and Long Island via an HVDC cable that runs right through 纽约 Harbor. 高压直流电缆安装于:

  • 尽量减少对环境的影响,保护纽约的风景
  • 避免架空输电工程经常造成的视觉影响
  • 最大限度地减少传统架空输电线路的电能损耗
这个项目需要什么样的维护?

The converter stations will have periodic maintenance performed on transformers and other electrical equipment as specified by the manufacturer. 对电缆进行连续监测, 除非检测到损坏, 它们实际上是免维护的.

这是一个安全的项目吗?

这个项目非常安全, utilizing solid-state cables that are made from well insulated nonflammable materials that do not contain liquids or gels that could leak. The HVDC converter stations are also solid state with no flammable fuel—unlike thermal generation stations. 尽量减少损失的可能性, the HVDC converter stations incorporate electrical protection systems that identify and isolate faults in a fraction of a second.

Will the project affect the commercial and recreational use of both the Hudson River or other waterways?

No. 这些水道的当前和未来使用将不受影响.

线路上需要做哪些维护工作?

对电缆进行连续监测, 除非检测到损坏, 它们实际上是免维护的. The converter stations will have periodic maintenance performed on transformers and other electrical equipment as specified by the manufacturer.

Is t在这里 any testing that will need to be done in waterways to make sure the lines can be placed in them?

在铺设电缆的水道上已经进行了各种测试. These include a side scan sonar analysis and bottom sampling of the riverbeds and lakes w在这里 the project will be located.

该工程将在什么电压水平下运行?

该项目将在300-320千伏之间运行,具体取决于所选择的技术.

2013年4月18日,PSC对你的项目做出了什么重大决定?

The 纽约 Public Service Commission (PSC) issued an order Granting Certificate of 环境 Compatibility and Public Need (permit). The commission found that the project had significant environmental benefits; provided needed transmission supply into a congested NYC load pocket; provided fuel diversity; connected renewable, stable-cost hydro resources into NYC; and strengthened the interconnection between the Quebec and 纽约 grids. 在纽约州建造这个项目需要许可证.

CHPE项目将如何与魁北克连接?

The CHPE project will connect to the Quebec transmission system by running matching HVDC cable past the 纽约–Canadian border and splicing it onto existing cable within the Quebec transmission system. 在加拿大这边, 该电缆预计将运行到蒙特利尔市附近的Hertel HVAC变电所. HydroQuebec will be responsible for the connection and infrastructure on the Canadian side of the border.

Response of 尚普兰哈德逊电力快车 to Questions Raised by Hudson River Drinking Water Intermunicipal Council

The Hudson River Drinking Water Intermunicipal Council (“Hudson 7”) requested additional information on the Project. 下面的文件是对哈德逊7号提出的问题和天博APP的回答的总结.

TDI问&哈德逊河取水口

这个项目要花多少钱?

该项目完全由私人资助,总成本约为60亿美元.

天博APP社区的建设需要多长时间?

阿斯托里亚-雷尼电缆获得批准,将于2024年5月开工建设, 该项目预计将于2025年底完工. 天博APP将在整个施工过程中继续向社区通报情况.

这个计划将如何改善我的社区?

CHPE will deliver 20 percent of remaining generation needed to meet 纽约 State’s 2030 renewable energy targets. 此外,热电联产所减少的碳排放量将相当于 纽约市街道上的汽车减少了约44%. The availability of renewable hydroelectric power eliminates the need for local fossil power generation in the Astoria area reducing local air pollution. The nature of hydroelectric power allows energy to be held in reserve via dams and re-leased as needed, 提供有弹性、可靠的天博app下载、可再生和负担得起的能源. CHPE将迅速帮助纽约开始向可天博app发电的未来迈进.

施工期间街道会封闭吗?

We are still evaluating existing field conditions and potential road or lane closures needed for construction. We will work with the DOT and municipalities to develop proper traffic control plans and communicate any temporary roadway restrictions with the community.

在施工期间,我可以完全使用我的房产吗?

Ingress and egress to homes and businesses will be maintained during construction; although that may mean it is provided through a temporary entrance as we access certain areas.

这对我的财产有什么影响?

建设将主要在现有的路权上进行. 如果天博APP需要额外的地役权, 项目团队将在施工前与您联系协调.

工程完成后,如何恢复路权和我的财产?

施工结束后,任何受影响的财产将恢复到原来的状态. Some locations along the route may see improvements to crosswalks and pavement to improve accessibility.

如果我在施工过程中需要额外的信息或有问题/顾虑,我该打电话给谁?
