万能式断路器全功能型智能控制器

Entire Function Type Intelligent Controller of Universal Circuit Breaker

提供了一个全功能型智能控制器的设计方案和思路,介绍了控制器的各个功能。控制器采用单片机实现实时监控、谐波的测量和分析,主要依据快速傅氏变换算法(FFT)得到基波值和高次谐波分量,利用基波值做各段保护,并在LCD上显示基波值及各次谐波值。结果表明,该控制器功能齐全,技术先进,满足了我国电力部门的要求。

Design plan and way of thinking of an entire function type intelligent controller with feasibility was provided. Introduction was made to each functionality of controller. The controller adopts singlechip to realize real-time monitoring, measurement and analysis for harmonious, mainly based on fast fourier transform algorithm（FFT） to obtain base wave value and higher harmonious component, using base wave value as protection for each section, and to be displayed the base wave value on LCD and each harmonious value. Results show that the controller is complete in functionality, advance in technology, meeting the requirements of power department in our country.
