Geothermal
Power
Geothermal power being used in utilities and power production use steam wells to supply heat to a steam turbine for power production. A typical geothermal system consists of steam turbines (flash steam, organic Rankine cycle, and/or pentane turbines), the steam gathering network and production wells, and water injection for a geothermal field. The task of steam system operators is to develop optimal operating strategies to achieve operational goals. The OptiRamp Geothermal steam solution can help users find the optimal steam production and steam distribution strategy to achieve their operational goals.
Steam Production Wells —Steam generation can be constrained by heat loss in the geothermal reservoir, alternate weather conditions, and process heat losses. OptiRamp can help sustain geothermal fields by
- Reducing heat loss while maintaining power production
- Improve process stability by allowing steam turbines to operate closer to target, constraint, and optimum values
- Identify and resolve pressure imbalance and bottlenecks in the piping network
- Maximize asset lifetime with alternate scenario of operation targets
- Optimize power generation with consideration of non-condensable gas and brine capacity limit
- Improve repair and maintenance planning and prioritization
Steam Distribution — Heat loss in a steam network can be a major contributor to operating costs and OptiRamp allows the user to see how efficient the steam network is distributing the steam and allows users to deliver the correct amount of steam to the right plant at the right time.
- Shows heat losses in steam distribution network
- Gives latent heat target compliance for ensuring correct amount of steam is delivered to the right power plant
- Provides a steam production and steam delivery balance summary to ensure protection of heat loss in the reservoir
