The Design And Implementation Of STATCOM Based On DSP-F2812

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.
