Steady State Phasor Modeling and Analysis of Hierarchically Switched Thyristor Controlled Phase Shift Transformer

采用相量分析法详细推导了移相角度、开关组态、等效阻抗之间的稳态相量关系,基于典型参数计算了移相器在不同开关组态下的等效阻抗、空载和负载移相角。实时数字仿真(real time digital simulation,RTDS)的计算结果表明,所建可控移相器相量模型能够准确反映实际装置在不同开关组态下的稳态运行特性。

The steady state phasor relations among phase-shifting angle, switch configuration and equivalent impedance are derived in detail by phase analysis; based on typical parameters, the equivalent impedance of the phase shifter under different switch configurations as well as the phase angle shifts under no-load and loaded conditions are calculated. Results of real-time digital simulation show that the established phasor model of the controllable phase shifter can accurately reflect steady state operational characteristics of actual thyristor controlled phase shift transformer under various switch configurations.
