  3. In the connection mode of distributed power supply and medium voltage double - looped network, the configuration of relay protection and safety automatic devices is analyzed, and the detailed cooperating relationship among current instantaneous break, over - current and spare power automatic switch device is also presented

    摘要在分散式供電、中壓雙環網接線方式下,對繼電保護和安全自動裝置的設置進行分析,並說明電流速斷、過電流和備自投裝置的具體配合關系。
  4. One - cycle control technique is conceived to control the duty - ratio d of the switch in real time such that in each cycle the average value of the chopped waveform at the output diode of the switch rectifier is exactly equal or proportioned to the control reference. it can eliminate automatically instantaneous error in every one cycle and the error belonging to the former cycle ca n ' t be brought to next cycle

    單周期控制技術的基本思想是控制開關的占空比,在每個周期內強迫開關變量的平均值與控制參量相等或成比例,它能在一個開關周期內自動消除瞬態誤差,前一周期的誤差不會帶到下一周期。
