Research On Static Reactive Compensation Device Controller Based On DSP

In the power grid,reactive Power is an important factor to the voltage stability,and it is also related to secure and steady operation of the power system.Reactive power compensation is one of the potent methods which can maintain effective and reliable operation of the power system.Based on the principle of TCR,a low voltage reactive power compensation system has been designed. The mainly content in this paper is as following:It primarily presents the development, features and main research direction of reaetive power compensation device at home and abroad. and recommends the basic structure of TCR system, working principle, perfect linear model and ordinary control methods.then emulate.In the hardware design,the paper mainly introduces controller and its periphery circuit.It is include Voltage, current signal acquisition circuit, low-pass filter circuit, phase-locked frequency multiplication circuit, threw cutting circuit, pulse amplifying circuit, thyristor protection circuit.The controller using TMS320LF2407DSP as control chip, the system makes full use of its speed and powerful features.In software this article mainly introduced the data acquisition module. FFT data processing algorithm, triggering pulse form module, LCD module. and mainly introduces FFT algorithm and how to form pulse Angle.Designed a set of low voltage reactive compensation device and texted.The experimental results show that the system design is reasonable. the control method and control strategy correctly and effectively, operation is stable and reliable, and achieve reactive power compensation required for further study, lay the foundation, has certain practical value.
