  1. The devices for detecting phase - to - ground fault in ineffectively grounded systems are seldom functionary at present. based on thousands of experiments in high - voltage laboratory in north china electric power university, the reasons for misjudgment and the effective measures to avoid it are presented in this paper : to change pt connection form to prevent from ill - effects of ferro - resonant overvoltage ; to increase soft measures to resist against interference ; to adopt neural network method to obtain the virtual value of the detect way

    依據上千次實驗，我們找到了一些導致選線誤判的影響因素，並提出幾點防止誤判的措施，包括改變pt接線方式，避免鐵磁諧振對選線的影響；通過對故障檢測方式的處理和使用連續判斷技術增強裝置的軟體抗干擾能力；嘗試採用神經網路演算法設定選線方法的有效域等。
  2. In order to consider the different heating of positive - sequence current and negative - sequence current of the motor stator generally, the equivalent current is adopted instead of the traditional phase current. the way how to gather positive - sequence current and negative - sequence current is brought forward, and the recurrence fourier - algorithm is adopted to calculate the effective value of current and voltage, the effective value of positive - sequence current and negative - sequence current

    為了全面考慮感應電動機定子正序電流和負序電流的不同發熱效應，提出了正序電流和負序電流獲取的方法，並採用遞推傅氏演算法來實現電流、電壓及電流正序和負序分量的有效值的計算。
  3. Based on the modularized asi, cascade inverter topology structure and modulation mode is introduced in this paper. comparing with several control strategies such as single closed - loop feedback and dual close - loop instantaneous value feedback, the voltage - current dual closed - loop control strategy, which is the voltage effective value feedback and inductance current instantaneous value feedback, is adopted

    針對級聯逆變器討論其pwm調制技術，在比較幾種pwm調制技術的基礎上，對該級聯逆變器採用倍頻載波移相調制技術，其輸出不含載波諧波，邊頻諧波次數比二階和三階調制的邊頻諧波次數提高一倍，等效開關頻率也提高一倍。
  4. The outer - loop adopting the voltage effective value feedback regulates voltage output and reduces the steady error of output voltage. the inner - loop control is inductance current feedback, which implements the stabilization of system, and limits the inductor current

    外環採用電壓有效值反饋，調節輸出電壓，內環採用電感電流瞬時值反饋，提高系統動靜態特性，並對採用該方案的級聯逆變器進行了全面分析。
