Problems solved by technology

Third, to manually test the surge curve of the turbo compressor, the compressor manufacturer needs to appoint a professional to conduct the actual test. Not only is the labor cost high, but it is also limited by time and space, and lacks timeliness.

Embodiment 1

[0060] see Figure 6 to Figure 11 , the inventor uses the following application cases to further explain the method of the present invention. In this embodiment, the turbo compressor is selected as the AV series axial flow compressor. First, programming is carried out according to the method steps of the present invention, and then the unit control system is used to automatically control the unit according to the program, and finally the anti-surge curve of the turbo-compressor is obtained.

[0061] Such as Image 6 As shown, in this embodiment, four expected surge test points are selected from the surge curve obtained by the aerodynamic calculation of the axial flow compressor to be tested: (330, 25), (395, 30), (480, 38) and (575, 49), according to step 2) to step 8) of the present invention, respectively input and carry out actual testing to the 4 determined surge test points, the working condition parameters of each surge test point obtained are as follows Figure 7 to F...

Abstract

The invention discloses an automatic surge testing method for a turbine compressor. The automatic surge testing method includes the steps: determining anticipated surge testing points; inputting the testing points; setting the turbine compressor; acquiring testing parameters; judging a surge condition; smoothly approximating and quickly breaking away from the surge condition; storing surge parameters; judging whether to continue surge testing or not, repeating the steps until all the anticipated surge testing points are tested if continuing surge testing, and ending the testing if not; generating a surge curve; and generating an anti-surge curve. The frequency of testing acquisition of condition parameters of the turbine compressor by a parameter acquirer is 300-500 milliseconds per time. The margin coefficient of the anti-surge curve ranges from 5% to 10%. The automatic surge testing method effectively avoids the problem that manual test of the surge curve of the turbine compressor easily causes big errors, reduces human input of surge testing of the turbine compressor, avoids violent change of the operation condition of the turbine compressor caused by emergency operation measures, and guarantees instant surge testing of the turbine compressor.

Description

technical field [0001] The invention belongs to the field of automatic control of compressors, in particular to a method for automatic testing of turbo compressor surge. Background technique [0002] The design of the turbocompressor is firstly based on the aerodynamic calculation and structural design of the parameters required by the associated process equipment for the compressor operating conditions. The performance curve (surge curve) of the turbo-compressor determined by the aerodynamic calculation includes the operating point required by the process device to ensure the matching operation of the turbo-compressor and the process device. During the manufacturing process of the turbo compressor, due to the irresistible deviation of manpower such as mechanical processing; during the on-site installation process, due to the deviation of the front and rear process pipelines and equipment settings, the performance curve (surge curve) of the turbo compressor will be different...
