Design Of Reactive Power Compensation Controller Based On DSP

This paper introduces development status of Compensation technology, analyze principle, capability and application area of different kinds of Compensation technology. Base on this and combining the improving application requirement, bring forward general project of use DSP to make Compensation control, also make system software and hareware design for that.In hardware design, use TI TMS320F2812as calculation and control core. This chip has following advantage:high calculation speed, abundance resource, low power concuming and strong anti-jamming capability. Data collection uses AD7656as main part which has16bits6channels can make high precision synchronization sampling. Switch part use SCR, and use zero voltage, zero current switch technology to make sure switch will not generate Harmonic and high frequency interference.In software design, DSP progrom use C language, take modularize design thinking for software development, use CCS3.3integration platform for program compile, debug and testing; Switch control software integrates power factor, Reactive power, light load atresia, over Compensation atresia control strategy, achieving full-scale integration control.
