  1. Based on the adaptive interference canceling theory and the concept of space vector, an adaptive fundamental positive / negative sequence component and harmonic component detecting method is developed. due to the close loop structure, this method has quite good robustness, and can meet the requirement of the asymmetrical control of hvdc - vsc well

    運用自適應干擾對消原理和空間矢量的概念，提出了一種基波正序分量、基波負序分量及諧波分量的自適應檢測方法，並進行了詳細的理論分析，為研究hvdc - vsc的不對稱運行控制奠定了基礎。
  2. A simple and easy operating criterion is put forward in accordance with the relation between positive - sequence component and negative - sequence component of stator current when the motor is in unbalance and single phase broken. based on analyzing the traditional inverse time - lag overloading protection of motors, an inverse time - lag operating equation with accumulating stator current is achieved, according to the differential equation of the heating and cooling while the current flows into the conductor

    在分析電動機傳統的反時限過負荷保護的基礎上，根據導體中流過電流時的發熱、散熱微分方程得到了累加定子電流的反時限過負荷保護動作方程，經簡化后得到累加定子電流的實用的反時限特性遞推公式。
  3. Aiming at the unsymmetrical three phase voltages from inverter after a failure, the dissertation get the relationship among the positive sequence ( ps ), negative sequence ( ns ) and the instantaneous symmetrical component of the ps, this build the foundation to detect the fault and to get the fault feature

    針對逆變器故障后的電壓輸出的不對稱性，利用對稱分量法對逆變器輸出信號進行分析，獲得了逆變器輸出信號的數字信號模型，為變頻調速系統的故障檢測與故障特徵提取奠定了基礎。 3
