Abstract

This paper presents the implementation of an electrical power system in MATLAB/Simulink and its execution in a real-time environment, called laboratory set-up for real-time power system simulation. This test-bed can help engineer and operator to learn the reaction of real power system in a virtual environment. Consistent to this issue, related software and hardware (National Instrument) are utilized to monitor electrical system variables, as well as analyze and evaluate power system stability in different real scenarios. The system implemented in MATLAB/Simulink, includes synchronous generator, power system stabilizer (PSS), excitation system and external grid. PXIe-8133 hardware allows user to execute different scenarios in the real-time mode. Also, LabVIEW DSC Module, a special monitoring system for industrial application, is used to access and flow data between several Vis. A program is developed in LabVIEW environment to initialize interaction between MATLAB generated *.dll file and LabVIEW via simulation interface toolkit (SIT) and in a parallel operation, data is simultaneously transferred between these two environments. EZDSP 320f2812 board is considered as hardware-in-the-loop (HIL). This feature helps engineer to implement control logic of power system equipment (here, real excitation system logic) in the DSP board. Based on the proposed idea, this board can serve as an emulator of real system and the functionality of control logic as well as its behavior is simulated and verified. This board and related potentiometer play the role of real excitation system and receive three-phase voltages and currents from NI PXI 7833R card. In return, the board generates excitation voltage and sends it back to PXIe-8133 and consequently, the loop will be closed. Finally, different scenarios in a power system are provided to show the application of real-time HIL system in the power industry as well as verification of proposed approach for training centers.

2. Implementace vybraných řidicích algoritmů pro FPGA

Abstract

Real-time počítač cRIO-9073 firmy National Instruments spolu se softwarem LabVIEW je všestranný nástroj využitelný v mnoha oborech, jak při výzkumu, tak při ryze praktických úlohách. Práce se zabývá studiem možností tohoto systému. Je cílena především na testování výkonnosti celého zařízení, možných omezení a ukázání jeho reálného využití při řízení procesů. Celý systém byl podroben testovaní s pomocí navržených aplikací pokrývajících široké spektrum využitelnosti. Systém cRIO umožňuje také využití dalších softwarových nástrojů při jeho programování. Tato práce zkoumá možnosti využití programu Matlab/Simulink od firmy Mathworks a také generování VHDL kódu s pomocí produktu firmy Xilinx. Cílem je porovnat náročnost programů na zdroje hradlového pole (FPGA) v cRIO a také množství výkonu real-time procesoru potřebného pro provoz daných aplikací., A real-time computer cRIO-9073 supplied by National Instruments, together with the software tool LabVIEW is a versatile system used in many fields, for both research and practical tasks. This thesis deals with the possibilities of the system. It is aimed primarily at performance testing, identifying potential limitations and showing its practical use. The whole system has undergone testing through the use of programs covering the wide spectrum of utilisation. cRIO also allows the use of other software tools in its programming. This thesis explores the options of using Matlab/Simulink from MathWorks and the generation of VHDL code using a product of Xilinx. The aim is to compare the demands on the resources consumed, by the Field-programmable gate array (FPGA) in cRIO as well as the CPU load running the Real-time process.
