應(yīng)用于電網(wǎng)絡(luò)試驗(yàn)臺(tái)的濾波器設(shè)計(jì)

摘要：本文設(shè)計(jì)了用于電網(wǎng)絡(luò)試驗(yàn)臺(tái)的混合有源濾波器，濾波器主電路采用二極管箝位型三電平逆變器拓?fù)浣Y(jié)構(gòu)，電流控制策略采用電流雙滯環(huán)控制。仿真結(jié)果表明，所設(shè)計(jì)濾波器能大大降低電網(wǎng)絡(luò)試驗(yàn)臺(tái)系統(tǒng)中諧波含量。 敘詞：電網(wǎng)絡(luò)試驗(yàn)臺(tái) 有源濾波器 電流雙滯環(huán)控制 Abstract：The paper designs hybrid active power filter for grid testing units. The main circuit of the filter adopts topology structure of diode-clamping three-level inverter, and current control strategy applies current double hysteresis control. Simulated experiments tell that the designed filter can lower greatly the harmonic in the system of the grid testing unit. Keyword：Grid Testing Unit, Active Filter, Current Double Hysteresis Control
