Oil or gas, dual power, turbine power station has an analysis unit with intermediate pressure turbine pressure sensor and an analysis unit for estimating the low pressure turbine power output

摘要

Oil or gas combined power turbine power station comprises: a steam turbine (2) with high, intermediate and low pressure steam turbines; a gas turbine (1) that is connected to the steam turbine via the same shaft; a generator (G) connected to the same shaft and; and an analysis unit (10). The analysis unit comprises: a pressure sensor for measuring the pressure at the inlet to the intermediate pressure turbine; an estimation unit for estimates a correction value for the low pressure output power; and an estimation unit which estimates the output power of the low pressure steam turbine based on the correction value and the measured steam pressure. An Independent claim is made for an operating method for a turbine power station.
