Novel electric energy quality multi-index data processing module

The utility model relates to a novel electric energy quality multi-index data processing module which is characterized by comprising an FPGA (Field Programmable Gate Array) chip; a sampling process is controlled, the obtained data is subjected to real-part calculation by virtue of a sine table, two real-part calculation multipliers and a real-part adder, and is subjected to imaginary-part calculation by virtue of a cosine table, two imaginary-part calculation multipliers and an imaginary-part adder, the output ends of the real-part calculation adder and the imaginary-part calculation adder form a complex number and the complex number is stored in a DFT (Discrete Fourier Transformation) result storage area in a DPRAM (Dual Ported Random Access Memory), the DFT result storage area of the DPRAM and a sample data storage area commonly output data to a DSP (Digital Signal Processor) to perform analysis and process of the electric energy quality. The design of the novel electric energy quality multi-index data processing module is reasonable, a parallel process way is used in the FPGA without very high clock frequency, thus very large data processing load is accomplished and the module has the characteristics of good real-time property, quick speed and the like. The novel electric energy quality multi-index data processing module is matched with the DSP for use, thus the integration degree of the system is improved and furthermore the high-speed electric energy quality data processing can be easily and conveniently realized.
