英文要約Title: Technological development for advanced management of operation in geothermal power generation system

This study is conducted for the purpose of constructing the operation assistance system using IoT-AI technology for the operation management of the geothermal power plant that is implemented based on the experience of the operators. With this system, power station troubles will be avoided and resolved beforehand, and the utilization rate of the geothermal power plant will be improved.
We build a system using AI to optimize O&M based on simulated operation data created from actual geothermal power plants data. Specifically, we will proceed with development from the following three perspectives.
1. O&M optimization of geothermal power generation system
2. Optimization of energy recovery
3. M2M sensor development
The following contents were implemented this year.
(1) Overall system design
-Design of system integration and design of operation verification method of system (examination of method by semi-simulated data of power plant )
- Setting of cloud server for effect verification by various AI tools
(2) Optimization of O&M of steam and brine transport facilities (wells, steam and brine transport facilities etc.)
- Hearing the situation of O&M of the existing geothermal power plant and investigating the situation of trouble and performance degradation
- Examine the factors, analyze the mechanism of trouble occurrence, and systematize the method of understanding the failure
(3) Optimization of O&M of geothermal power plant (turbine, generator, condenser, cooling tower, etc.)
- Hearing the situation of O&M of the existing geothermal power plant and investigating the situation of trouble and performance degradation
- Examine the factors, analyze the mechanism of trouble occurrence, and systematize the method of understanding the failure
(4) Development of steam production network simulator
- Basic design and development of underground two-phase flow simulator (addition of automatic calculation function of wellhead production characteristic curve)
- Basic design of steam production network simulator
(5) Development of geothermal-specific M2M sensor technology
- Survey on current status of M2M sensor technology (manufacturer interview) and organization of sensor technology available in geothermal environment
(6) Optimization of Geothermal Power Generation Equipment O&M utilizing AI technology
- Survey on current status of M2M sensor technology (manufacturer interview) including Drone and Test of Drone
- Conceptual design of estimation system of steam and hydrothermal system combined steam control system
