This paper describes a novel concept for integrating binary plants at a geothermal site which has been realized within a demonstration project in Indonesia. By using an intermediate hot water and an intermediate cooling water cycle it is possible to integrate a fully-automated binary plant with flexible operation in an existing, predominantly manually operated geothermal field. The paper gives technical component details and describes specific design considerations of the demonstration power plant. Furthermore operational data and experiences are shared. Current binary plant operation is characterized by many starts and stops because of several technical challenges, e.g. electrical grid conditions, as well as by off-design conditions. The proven maximum power capacity until now is approximately 400 kW. By means of a numerical model it is shown that the design capacity of 500 kW can be reached.

利用印度尼西亚的地热盐水：二元示范电厂Lahendong / Pangolombian

本文介绍了在地热场整合二元植物的新概念，该概念已在印度尼西亚的一个示范项目中实现。通过使用中间热水和中间冷却水循环，可以在现有的，主要是手动操作的地热领域中集成具有灵活操作的全自动二元设备。本文提供了技术组件的详细信息，并描述了示范电厂的具体设计注意事项。此外，运营数据和经验是共享的。当前的二元工厂运行的特征是由于多种技术挑战（例如电网条件以及非设计条件）而启动和停止很多。迄今为止，已证明的最大功率容量约为400 kW。
