VLT®驱动器运行世界上最聪明的地区能源系统

2020年9月29日，星期二

丹麦：大哥本哈根塔尔比市的建筑所有者，由于世界优先的项目，哥本哈根大哥本哈根享受竞争价格和环保的冷却。该项目将区域冷却和地区供暖的生产与地面源冷却和冷藏储水组合结合在一起，这也可以利用附近的废水处理厂的多余热量。共生公司不仅可以为居民提供竞争价格的冷却，还可以为地区供暖网络提供更具成本效益的供暖。

扇区耦合使可再生能源充分利用
2000立方米冷藏水箱的储能容量为13 MWH

扇区耦合使可再生能源充分利用

该项目是行业耦合的一个很好的例子，在价格低时提供了一种使用绿色可再生电力的方法，并避免在高峰时段以高价的高峰时段消耗电量。

在新的Taarnby设施中，剩余的绿色电力被引导到一个组合的加热和冷却系统中，该系统将能量存储在冷水中。得益于一个冷藏的储水箱，可以容纳2,000立方米的冷水，Taarnby Utility能够应对电力市场的波动，并在电价低时产生冷却。此外，储罐可以提供峰值容量并稳定热泵的运行。

聪明的消费者

在丹麦，超过45％的电力生产来自可再生能源，低电价通常表明风能盈余供应。从电力系统的角度来看，Taarnby实用程序成为了聪明的消费者。提供急需的能源需求响应，Taarnby可以在电力供应商需要出售时购买电力，例如，当天气条件最适合发电和/或电网上的高峰时段以外的情况下。同样，在发电或发电能力短缺的情况下，生产可能会受到干扰。

合伙企业协同作用

该独特的项目于2020年委托，由Ramboll Consulting Engineering Company设计，主要利益相关者是本地建筑所有者，Taa体育投注必威rnby公用事业公司和热传输公司CTR。这些利益相关者与寻求环境友好和成本效益的解决方案之间的合作是Taarnby设施的开发和实施的关键。

地区供暖和冷却案例研究

SCOTLAND: In line with the zero-waste objectives of the Scottish government, treatment of non-recyclable urban waste contributes to eliminating landfill whilst generating electricity and heat. Equipped with high-efficiency VACON® NXP drives, the process generates heat enough to supply 25,000 households.

Taarnby Municipality within Greater Copenhagen is the first to integrate the production of district cooling and district heating in combination with ground source cooling and chilled water storage in one facility that also exploits surplus heat from a nearby wastewater treatment plant. This symbiosis allows the utility company to provide building owners in the district with competitive and environmentally friendly cooling – while generating more cost-effective heating to the district heating network.
