Two and characteristic

1. Multifunctional integrated comprehensive experimental device, fully display the entire process of modern electricity power generation, grid grid, and transmission.

2. The m--n equipment of the experimental platform: experimental desk, control cabinet, generator set, three -phase adjustable load, etc.

3. Control cabinets include three major parts: microcomputers for the same period, microcomputer excitation device, microcomputer speed regulating device.

4. Can carry out complete electricity experiment content: the start and moving of the generator set, the excitation control of the synchronous generator, the simultaneous part -time operation of the synchronous generator, the system stability experiment, the single -machine load experiment, the system side experiment, etc. More than a dozen types of experiments.

5. Microcomputer device human -machine interaction interface adopts large -capacity, high and clear 7 -inch color touch screen, which can display the voltage, current, frequency, non -meritority and other electrical parameters of the system in real time. Interactive, the menu Chinese shows, and the graphic and text is full of graphics.

6. Micro -machine device adopts DSP+CPLD high -end chip: In order to meet the needs of the experimental platform control system, high -performance, high -precision industrial control 32 -bit fixed -point DSP controller is used to achieve data processing with software. Meet the requirements of large computing quantities and high computing speed; CPLD is a complex programmable logic device that uses computer -assisted design technology to configure the designed data file into the static data memory (SPAM) inside the chip. Sex can flexibly configure the hardware logic circuit, reduce the space and complexity of the PCB board, and improve the reliability of operation. The DSP+CPLD is combined and applied to the experimental platform control, and the improved control algorithm and hardware structure are improved, so that the entire control system meets the requirements of fastness, accuracy and stability.

7. Artificial intelligence and adaptive PID control: In order to achieve accurate, stable, and secure adjustment of the speed and output voltage of the generator, eliminate the oscillating phenomenon in the control process, this device combines the conventional PID controller with the self -reliance algorithm combined and utilized The artificial intelligence system automatically adjusts the PID parameter at every moment of the system state change, so that the control process is always in a ** state.
