Embodiment Construction
[0128] The real-time monitoring method for the internal loss of the water turbine proposed by the invention has a simple algorithm, and its core is the formulation of coefficients in the water turbine model. The following steps are included in the specific implementation.
[0129] Step 1: Determine the efficiency curve used to calculate the coefficients and calculate the characteristic parameters
[0130] 1) Calculation using the comprehensive characteristic curve of the model:
[0131] According to the unit parameters, select the rated water head H r For the corresponding unit speed, read the data from the comprehensive characteristic curve of the model, draw the efficiency curve under the rated water head, and determine the highest efficiency point. Find the flow Q at the point of maximum efficiency z , Output N z . The hydraulic loss coefficient f of the water diversion system p Estimate based on actual piping layout.
[0132] 2) Calculated using the measured efficie...
