Development of Gas Turbine Fast Mathematical Model Simulation Module for Software Complex «Electrodin» based on LabVIEW

Abstract

This work was carried out within the framework of the project which purpose was to create a multi-adaptive ecological test rig for gas turbines up to 40 MW for such objects as gas pumping units (GPU) and Abstract. A fast mathematical model simulation module based on LabVIEW graphical programming environment has been developed. The module will be used for gas turbine and electrical power system co-simulation, and for testing automation of gas turbine automatic control systems.

Principles of Imitation for the Loading of the Test Bench for Gas Turbines of Gas Pumping Units, Adequate to Real Conditions

“…Then, the mathematical model is identified and checked for adequacy according to Theil's criterion [31]. The obtained parameters of the model are written to a file of the format .xml [32].…”

“…Let us consider mathematical models of gas turbine units and gas pumping units operated at enterprises. To study power plants, it is advisable to use simplified identification models [8,32], which, nevertheless, should adequately reproduce transient processes in power plants and nonlinearity of characteristics when changing the operating mode of the plants. Power plants interact with synchronous generators mechanically, thus, bringing the models of power plants to a single generalized form, as shown in [8], is not required.…”

“…The parameters of the models of power plants are obtained using the Calculation Application (Block 4 in Figure 12) [32] and are entered into the simulation module on the LabVIEW platform through files of the .csv and .xml formats. Further, the software and hardware modeling of the electric power system is carried out.…”

“…The structure of the gtuSimulatorProject.lvproj project [32] is shown in Figure 13. The GtuSimulatorMain.vi block diagram is shown in Figure 14.…”

Software and Hardware Complex of Experimental Plant for Pulp and Paper Production

“…Additionally, the controller is equipped with input and output modules of analog and digital signals, as well as with the line of communication modules (Ethernet, Modbus TCP, CC-Link). A special program implementing the connection between the PLC and the upper level is recorded in the PLC [7,8]. In the upper level, a project of the dedicated SCADA system based on LabVIEW DCS Module and the application for processing and analysis of experimental data have been developed.…”
