  1. By analyzing the basic principle of voltage space vector pwm, a method is proposed to choose the zero vectors dynamically according to the power factor angle of the load and the concept of the lag angle of non - switching sectors

    在分析了空間矢量pwm基本原理的基礎上,提出了一種根據負荷角動態分配矢量的方,並引入了不開關扇區滯后角的概念。
  2. Reactive power are calculated using the new algorithm. on the basis of analyzing different kinds of control strategies of var compensation, the paper applies the criterion of voltage and var to control switching and illustrates a improved mode of switching capacitor which can prevent the switched - capacitor from the impacting of instantaneous rush currents by means of zero - crossing triggering of scr components, and can realize auto - tracking var and auto - switching shunt capacitor bank. initial operating parameters are stored in information flash memory of the mcu using flash self - programming technique in order to decrease complexity of the circuit and improve stability

    高壓智能無補償控制器以flash型16位單片機msp430f149為控制核心,採用了一種相角實時測量的新演算,並在此基礎上計算出了、有和無,減少了運算量提高了精度;在分析了各種無補償控制策略的基礎上,以母線電壓和無復合判據控制投切,並提出一種改進的電容器投切方式? ?暫態投切控制晶閘管過觸發,避免了電容器投切時的電流沖擊;穩態運行時接觸器替代晶閘管,實現無補償的自動跟蹤和電容器的自動投切,解決了投切時的暫態電流沖擊和穩態時可靠運行的難題;控制器的原始運行參採用flash自編程技術,將其保存在msp430f149片內的信息flash中,簡化了硬體電路,大大提高了系統的可靠性。
