BPPT has developed and operated a 3 MW Geothermal Power Plant (GPP) of a condensing type technology in Kamojang, West Java - Indonesia, which is the first prototype GPP manufactured by Indonesian companies. The BPPT’s pilot plant was designed based on the geothermal steam field of the KMJ-68 well. The pilot plant becomes an early stage for developing wellhead type GPP in Indonesia. The wellhead GPP can meet with the capability of local manufacturers in the turbine and generator. The local content of BPPT’s pilot plant has reached 63.14 %. This paper discusses the design of Process Flow Diagrams (PFD), performance, and reliability of this plant during continuous synchronous testing to the 20 kV local power grid on November 21–25, 2019. This test is intended to fulfill the requirements to get a Certificate of Operation (SLO). The proposed SLO is for operation at a nominal power of 2 MW considering the limited capacity of the KMJ 68 well. As a technical requirement to obtain the SLO referred to, the plant must be operated continuously for 3 x 24 h in a power range of 1.8–2.2 MW. The utilization efficiency of the GPP was 29 %, which quite good considering dry steam geo-fluids condition. The specific steam consumption (SSC) achieved 14 kg/kWh. The plant still has an opportunity for improving efficiency by reducing the pressure loss in the steam strainer, increasing the condenser vacuum, and improving the turbine design and fabrication. The important aim in this testing was that the plant has operated by following the electricity demand fluctuation in the 20 kV PLN grid. This testing progress becomes a promising stage for the development of GPP’s equipment with local manufactures.

BPPT在印度尼西亚西爪哇省的卡莫让开发并运行了一种冷凝式技术的3兆瓦地热发电厂（GPP），这是印度尼西亚公司制造的第一批GPP原型。BPPT的中试工厂是根据KM J的地热蒸汽场设计的-68好。中试工厂成为在印尼开发GPP井口装置的早期阶段。井口GPP可以满足涡轮和发电机本地制造商的能力。BPPT中试工厂的本地含量已达到63.14％。本文讨论了在2019年11月21日至25日对20 kV本地电网进行连续同步测试期间该工厂的过程流程图（PFD）的设计，性能和可靠性。该测试旨在满足获得要求的要求。操作证书（SLO）。考虑到KMJ 68井的能力有限，建议的SLO可在2 MW的额定功率下运行。作为获得SLO的技术要求，该设备必须在1.8-2.2 MW的功率范围内连续运行3 x 24小时。GPP的利用率为29％，考虑到干蒸汽地质流体的条件，这相当不错。单位蒸汽消耗（SSC）达到14千克/千瓦时。该工厂仍有机会通过减少蒸汽过滤器中的压力损失，提高冷凝器真空度以及改进涡轮机的设计和制造来提高效率。该测试的重要目的是通过跟踪20 kV PLN电网中的电力需求波动来运行工厂。该测试进展成为与本地制造商一起开发GPP设备的有希望的阶段。以及改善涡轮机的设计和制造。该测试的重要目的是通过跟踪20 kV PLN电网中的电力需求波动来运行工厂。该测试进展成为与本地制造商一起开发GPP设备的有希望的阶段。以及改善涡轮机的设计和制造。该测试的重要目的是通过跟踪20 kV PLN电网中的电力需求波动来运行工厂。该测试进展成为与本地制造商一起开发GPP设备的有希望的阶段。
