低壓開關(guān)及控制MATLAB仿真

1、低壓開關(guān)及控制實(shí)驗(yàn)?zāi)康模?. 掌握高壓斷路器和低壓開關(guān)的區(qū)別。2. 熟練運(yùn)用MATLAB中的電力系統(tǒng)工具箱對(duì)理想低壓開關(guān)電路進(jìn)行建模， 觀察分析其波形。實(shí)驗(yàn)內(nèi)容：(1)如圖1.1所示，構(gòu)建理想開關(guān)電路，觀測(cè)理想開關(guān)的投切效果。開關(guān)未并 聯(lián)緩沖電路，導(dǎo)通時(shí)電阻為0.01 Q,開關(guān)初始為合閘狀態(tài)，0.06 s時(shí)開關(guān)斷開, 0.165 s時(shí)重合閘成功.圖1.1(2)設(shè)置模塊參數(shù)和仿真參數(shù)。雙擊理想開關(guān)模塊，按圖1.2設(shè)置參數(shù)。雙擊定時(shí)器模塊，按圖1.3設(shè)置開關(guān)初始為合閘狀態(tài)，0.06 s時(shí)開關(guān)斷開，0.165 s時(shí)再次合閘。電壓源Vs的有效值為120 V,頻率為50 Hz。串聯(lián)RLC支路中，電阻R=
