The Application And Research Of Controllable Reactor In Reactive Power Compensation

In Power system，reactive Power is an important factor to the voltage stability，and it isalso related to secure and steady operation of the power system.Reactive power compensationis one of the potent methods which can maintain effective and reliable operation of the powersystem.Based on the principle of TCR，a low voltage reactive power compensation system hasbeen designed. The mainly content in this paper is as following:1、It primarily presents the development, features and main research direction ofreaetivepower compensation device at home and abroad. and recommends the basic structure of TCRsystem, working principle, perfect linear model and ordinary control methods.2、In hardware design the paper mainly introduces controller and its periphery circuit.It isinclude Voltage, current signal acquisition circuit, low-pass filter circuit, phase-lockedfrequency multiplication circuit, threw cutting circuit, pulse amplifying circuit, thyristorprotection circuit.The controller using TMS320LF2407DSP as control chip, the system makesfull use of its speed and powerful features.3、In software this article mainly introduced the data acquisition module. FFT dataprocessing algorithm, triggering pulse form module, LCD module. and mainly introduces FFTalgorithm and how to form pulse Angle.4、Designed a set of low voltage reactive compensation device and texted.Theexperimental results show that the system design is reasonable. the control method andcontrol strategy correctly and effectively, operation is stable and reliable, and achieve reactivepower compensation required for further study, lay the foundation, has certain practical value.
