Abstract:
1. A load fuzzy modeling device for a power system based on a causality diagram, a composite cloud generator and an improved T-S fuzzy model, comprising: a hardware device including the upper and lower devices, which includes sensors, a signal conditioning and filter module, an A/D conversion module, a causality conversion module, a DSP module, a memory module, a display and keyboard module, and a communication module, wherein the sensors, the signal conditioning and filter module, the A/D conversion module, the causality conversion module, the DSP module, the memory module, the display and keyboard module and the communication module are connected with the DSP module respectively, and the upper device is connected with the commutation module; a voltage and a current are respectively acquired from the system through a voltage transformer and a current transformer, and then transmitted into the filter circuit for filtering, thus amplified through a amplifier LM258P as the voltage within the range of −5V˜+5V so as to input into the A/D conversion modules for sampling; a digital signal simply processed by the causality conversion module according to certain analysis algorithm principle, and the processed signal transmitted into the DSP to process, the final results thus displayed on the LCD screen and transmitted into the PC through the commutation module.
