The Software Design And Development Of The New Generation Simulation Excitation System Of The Synchronous Generator

The dynamic simulation of power system is indispensable test tool of carrying on the research of the new technology in power system and technical training of power industry. The simulation excitation device of synchronous generator is one of the capital equipment of dynamic simulation of power system, which completes the dynamic emulation of the power system with other dynamic simulation apparatus together. With the enlargement of the generator capacity and scale of electric grid day by day, Have put forward higher and higher requirement of promptness, dependability and robustness in excitation system etc, In order to imitate various excitation operating modes more accurately, This paper has designed the simulation excitation device controlled by high speed digital signal processor TMS320F2812. In order to realize the total digital controlling dynamic simulation of the excitation in power system can imitate many kinds of excitation models such as separately excited, self-excited, exciter excitation etc, have strong ability of anti-interference and real-time character, have the good man-machine interactive interface.At first, this paper has introduced current situation of the development of the domestic and international research of the simulation excitation system, and has explained the computer controlled relevant principle of the new generation simulation the excitation system in detail.The simulation excitation adjuster is the key controlling unit of the whole simulation excitation system. Introduces the way of data sample and its processing module, controlling and adjustment module, moved phase and touching module, LCD display and protection and module's program design based on hardware of the simulation and excitation adjuster and TMS320F2812's configuration definitely, supply the main program and each module's flow chart. Use C language and assemble language to design the program. Founded the simulation excitation adjuster's math model and simulated it in the MATLAB/SIMULINK environment, the result of the simulation validates the feasibility of the simulation excitation system in theory. Debug the program in the CCS 3.1 environment. Have summarized the questions and experience met in the course of project implementation, made the plan of the software design and carried it on the hardware design for the simulation excitation system based on DSP technology, have established the theoretical foundation for realizing the excitation system of digital simulation finally.
