使用Vacon®驱动器的地热功率恢复独特的热量

2020年9月14日，星期一

澳大利亚：在澳大利亚干旱的内陆澳大利亚中，从地下抽出的井水很热，需要冷却才能喝。昆士兰州的温顿镇通过将热量从钻水转换为电力，使它成为其优势。地热发电站在井水冷却过程中恢复了能源，然后将其用于为当地社区产生电力。

通过先进技术恢复热量

温顿通过将热量倾倒到大型冷却池塘中来冷却该镇的井水。为了利用这种热量而不是将其丢给大气，他们安装了一个地热发电站，该电站由Green Thermal Energy Company GTET从Greenfield站点设计和传递。该装置使该镇的孔供应从86°C冷却至53°C。发电站恢复热量，然后使用它使用GTET的两个前沿发电机来发电。

超出效率预测

电站的总体性能已超过建模预测高达10％，在这里，驱动器的效率是重要的贡献者 - Vacon®驱动器是发电系统中不可或缺的组成部分。

温顿地热植物的设计模型预测了100 kW的净发电，用于测量的投入

  • 在85.1°C的温度下以每秒30升流动的水钻水，并且
  • 在19°C温度下冷却水，以每秒128升流动

由于总发电能力超过300 kW，实际产出已被证明高达110 kW。

Vacon®驱动器是兽人发电机不可或缺的

Vacon®驱动器是兽人发电机不可或缺的

Vacon®驱动器是GTET ORC发电机中不可或缺的组件，该组件可冷却井水并使用回收能量产生动力。GTET主要用于控制ORC发电机中使用的微型涡轮增压器所需的高速再生能力。Vacon®驱动器也是选择过程中最经济上最可行的解决方案。

两个ORC发电机每个包含一个集成的Vacon®驱动器，包括

  • Vacon®NXP网格转换器
  • Vacon®NXI逆变器
  • LCL过滤器

该站点还使用Micro Grid应用程序运行单独的Vacon®NXP网格转换器，并连接到75 kW的电池存储。

认证打开了新的机会

认证打开了新的机会

澳大利亚丹佛斯（Danfoss Australia）和丹佛斯（Danfoss）在芬兰（Finland）定期支持GTET，并在浏览AS4777：2015认证过程的同时解决了技术查询。

2019年11月获得了认证，并克服了GTET获得其任何澳大利亚兽人发电机安装的连接批准的重要障碍。现在，该认证已经到位，将来将顺利进行类似项目的航行。

GTET董事总经理Paul Keen解释：

“Vacon®驱动器解决方案提供了有效控制GTET涡轮机所需的功能，其能量损失最小。因此，集成驱动器解决方案是GTET ORC发电机中的关键组件。”

每年节省100,000澳元

每年节省100,000澳元

地热发电站是澳大利亚唯一同类的地点，因此，该独特的项目还为温顿镇提供了巨大的促销，营销和旅游机会。

地热电站每年可节省大约100,000美元，包括节省和积分。此外，它还减少了通过冷却池冷却城镇供水所需的能量。

难怪Winton理事会对完成的项目感到非常高兴和兴奋，并且正在与州和联邦政府和公众大力促进该地点。

NORWAY: The Hareid-Sulesund ferry operations have reduced CO2 emissions by 7000 tonnes annually with the introduction of electric vessels. In transitioning ferries from diesel to pure electric power, powerful onshore support is essential, in the form of reliable infrastructure for rapid charging capacity and stable grid supply. The systems on board and on shore act as a single system – a sophisticated and competitive system developed by Norwegian Electric Systems (NES) using Danfoss technology.
