Self-adaptive hydropower station real-time water affair calculation method

The invention discloses a self-adaptive hydropower station real-time water affair calculation method, which comprises the steps of acquiring water level sensor data to calculate a water purification head, acquiring initial and final water level values of a time period to calculate reservoir tolerance difference flow, acquiring a unit state to calculate unit power generation flow, acquiring a gate state to calculate gate discharge flow, and calculating reservoir flow according to a water balance formula. And performing rolling smoothing processing on the reservoir flow to obtain a real-time reservoir flow fluctuation trend which is used for flood control early warning response. According to the method, all operation conditions of a hydropower station without a reservoir hydrological station can be automatically judged, different water level sensors are selected to participate in calculation, data collected by the sensors are subjected to smooth sawtooth elimination, and the reservoir tolerance difference flow
