摘要:
电力系统的谐波是影响电能质量的重要因素，谐波对电力系统和用电设备产生了严重危害和影响。文中针对现有电网谐波表对谐波检测实时性不高和精度低的问题，提出一种基于NiosⅡ软核和FFTrIP核为核心的电网谐波表的设计方法。设计中FFTP核、键盘、显示等模块通过用户自定义外设组件的形式添加到SOPCBuilder中，同时通过Avalon-ST总线有效地把FFTT1P核与NiosⅡ软核处理器有机地结合起来，实现控制灵活、高速实时的电网谐波表。该设计已在Ahera芯片EP2C35F672C6上进行实现，能够满足100MHz的系统时钟，提高了实时性
Abstract:
Harmonic is an important influence of power quality in power system,for it is harmful to the power system and power equipments. A technique for realizing harmonic measurement based on the Nios Ⅱ which makes use of Nios Ⅱ soft-core processor to obtain the real-time measurement and analysis is presented to solve the problem of low speed and low accuracy of harmonic measurement system in existence. Through the Avalon-ST bus effectively combined the FFT 1P core and Nios II soft-core,greatly improving the system processing speed and efficiency and achieving a flexible, high-speed real-time control of the electrical network parameter monitoring system. This design has carried on the timing simulation on Altera chip EP2C35F672C6, can satisfy 100MHz system clock, improve the real-time
