Status inference

Based on available measurements and the operator’s knowledge about their power plant, different statuses can be inferred. Detecting accelerating speed from standstill would typically mean a start in progress. A unit where generator power changes from 0 to “something” (dependent on turbine type and unit capacity) would mean that a start has happened. Using spectral analytics on proximeters and accelerometers can possibly infer status for some of the stages in start / stop. Penstock and turbine pressures (each side of the Main Inlet Valve) can infer to the early stages of a start. The key for status inference is collaboration with the customer to decide what statuses are valuable to infer for the specific plant.
