Abstract

A system and a method for determine that performance of a helium turbine power generation system under an off-design condition belong to the field of data processing. Existing methods for determiningthe performance of power generation system under off-design conditions by using EXCEL form coordinate paper have the problems of hand-drawn standard curves, more human interference and large error, which lead to poor accuracy in determining the performance of power generation system under off-design conditions. The invention calculates the data read by the input module through the operation module, The standard curves which reflect the relationship between helium turbine flow rate, turbine inlet temperature, component efficiency, cycle total pressure ratio, efficiency optimum pressure ratio, surge margin, high / low pressure compressor inlet temperature and helium turbine power generation system performance under off-design conditions are plotted. Through the query module, the data read by the input module and the standard curve obtained by the operation module are queried for the value of influencing factors. The invention can quickly inquire and obtain the corresponding performance value of the power generation system under the variable working conditions, and has strong pertinence.

technical field [0001] The invention relates to the field of data processing, in particular to performance determination of a turbine power generation system under variable working conditions. Background technique [0002] Using the EXCEL form coordinate paper to draw the standard curve method to draw the standard curve by hand, there are many human factors interference, which will lead to a large error in the drawn curve, so that the accuracy of the results obtained from the curve will lead to the performance of the power generation system under variable working conditions. [0003] The purpose of drawing the curve is to represent the flow rate of the helium turbine unit, turbine inlet temperature, component efficiency, total cycle pressure ratio, optimal pressure ratio for efficiency, surge margin, and high / low pressure compressor inlet temperature. The numerical value is related to the performance of the power generation system under variable working conditions, so the ex...
