摘要
提出一种基于可控电抗器的双调谐滤波器控制技术。该控制技术通过调整可控电抗器交流电感值,将滤波器从失谐状态调整到谐振状态,从而有效滤除系统中的谐波成分。同时结合晶闸管投切电容器快速跟踪补偿系统所需无功功率的特点,设计了一种混合型动态无功补偿滤波装置,该装置克服了传统双调谐滤波器滤波性能易受系统频率偏差、器件参数漂移、系统阻抗变化等因素导致的滤波器失谐及不能动态跟踪补偿负载所需无功功率的缺陷。通过MATLAB/Simulink建立仿真模型,仿真结果验证了装置的可行性和优越性。
A control technology of dual tuning filter based on controllable reactor is put forward,which regulates the AC inductance of controllable reactor to for effective filtering out the harmonic components of adjust the filter from detuning state to resonant state system. A hybrid dynamic reactive power compensation and filter device is designed,which adopts the TSC（Thyristor Switched Capacitor） to quickly trace the reactive power needed by the compensation system and the proposed control technology to avoid the detuning of traditional dual tuning filter cased by system frequency deviation,component parameter drift,system impedance change,etc,and the deficiency that required reactive power of load can＇t be dynamic tracked. A simulation model is established on MATLAB/Simulink platform and the simulative results demonstrate the feasibility and superiority of the designed device.
