The purpose if this article is description the interaction features of compression station control SCADA system with the external software of the centrifugal compressor volute technical state estimation for compressor 16ГЦ2-395/53-76С of the compressor station “Dolyna”. The data exchange between the developed software and the SCADA system is implemented using Dynamic Data Exchange technology, which has a client-server architecture.
This software is created in the mathematical environment Matlab and includes parameters indetification of the centrifugal compressor mathematical model, the creation of its empirical model, calculation changes in the technical condition estimations and the expert assessment of the compressor technical state, which allows to estimate the current compressor technical state during its operation and it prevents the faults appearance, reduces the technical control cost. The output data values are the compressor volumetric flow rate values, which depend on the input parameters and the flow rate geometric dimensions. Experimental parameters were collected the operation of the gas pumping plant С1-16С/76-1for two months: November of the year 2014 and February of the year 2015.
The developed software integration into the existing compressor station control system involves the special application creation written in the object-oriented programming language Delphi. This application is connected to the Matlab software environment using COM technology, and data exchange involves the use of PutFullMatrix and GetFullMatrix functions.
