Abstract
A geothermal management system may receive time-series data for operation of the geothermal energy system. A geothermal management system may calibrate a physical model using the time-series data. A geothermal management system may apply the physical model to a pre-determined comparison parameter to generate a performance indicator. A geothermal management system may identify an operating status of the geothermal energy system based on the performance indicator.
Claims18
A method for monitoring a status of at least a component of a geothermal energy system, the method comprising:
- receiving time-series data for operation of the geothermal energy system from a set of sensors, wherein the set of sensors comprises a temperature sensor, a power monitoring sensor, a flow rate sensor, and a pressure sensor,
- wherein the time-series data comprises temperature data from the temperature sensor, power data from the power monitoring sensor, flow rate data from the flow rate sensor, and pressure data from the pressure sensor;
- filtering the time-series data to obtain filtered time-series data;
- calibrating a model by fitting a set of coefficients of the model to the filtered time-series data, wherein the model emulates a behavior of the component using the filtered time-series data;
- inferring at least a first operational parameter and a second operational parameter of the geothermal energy system from the filtered time-series data, wherein the model infers the first operational parameter based on the second operational parameter;
- applying the model to a pre-determined comparison value of the second operational parameter to generate a performance indicator comprising a predicted value of the first operational parameter at the pre-determined comparison value;
- identifying an operating status of the geothermal energy system based on the performance indicator, wherein the operating status specifies a maintenance status of the component;
- and
- generating a recommendation based on the operating status, wherein the recommendation specifies adjusting the first operational parameter.
