基于DSP-F2812的STATCOM的设计与实现
|
摘要
随着电力产业的不断的发展,大量非线性负载的涌入,无功容量不足、谐波等问题也给电力系统安全稳定的运行带来了一定的问题,因此无功补偿设备的发展变得越来越重要起来。
鉴于目前部分无功补偿手段相对落后,不能很好的满足补偿精度、补偿同步性的要求。本文针对以上问题,对低压配电网静止同步补偿器(STATCOM)的研发,提出了设计方案。
系统无功参数的提取和检测对于无功补偿精度、同步性起着至关重要的作用。因此,本文在传统的瞬时无功理论、预测电流法的基础上提出了一种改进的预测电流法。提高了补偿精度及补偿同步性的问题,并在任意次谐波的检测与补偿上有了一定的发展。给出了信号检测的电路设计,并对该部分设计进行了较为详尽的阐述。并有采样电路的成型,得到了系统信号。并阐述了该电路与控制单元的连接方式。
利用MATLAB-Simulink对系统进行了仿真实验,并以DSP开发板为核心,对系统进行了开发。利用MATLAB-RTW、CCS结合的方法对控制代码进行了开发,大大缩短了DSP开发的周期,并且仿真结果及实验结果证明系统满足了无功检测及补偿的要求。给出了控制代码的开发流程图。
With the continuous development of power industry, a large influx of non-linear load turn up and insufficient reactive power capacity, harmonic and other issues has become a safe and stable operation of power system, it has brought some problems, so reactive power compensation equipment is developing more importantly.
Since at present some reactive power compensation ways dropped relatively behind and do not satisfy with the accuracy and synchronization of compensation. For these issues, this paper researches the low voltage distribution network static synchronous compensator (STATCOM), and proposed design package.
For the accuracy and synchronization of reactive power compensation, the detection and the extraction of reactive power parameters play a important role. Therefore, this paper based on traditional instantaneous reactive power theory and prediction current method, proposed an improved prediction current method. It not only increases the accuracy and synchronization of compensation, but also has a certain development in any harmonic detection and compensation.This paper gives out the design of the detection unit, and expounds this part in detail. Gets the signs of the system under the circuit. At the same, the paper also expounds the connection between the detection unit and the control module.
Using MATLAB-Simulink on the system and developing the system whose core is DSP development board. Using MATLAB-RTW, CCS combination method researched the control code, it greatly reduced the DSP development time, and finally the simulation results and experimental results show that the system satisfied all requirements for the detection and compensation of the reactive power. Under the job, the paper offers the progrem flow chart of the control code.
