資源簡(jiǎn)介
傳統(tǒng)配電網(wǎng)潮流計(jì)算僅關(guān)注預(yù)想場(chǎng)景下電網(wǎng)中的電氣量運(yùn)行狀態(tài)（如節(jié)點(diǎn)電壓、相角，線路載流、功率等），未考慮輸電元件運(yùn)行的溫度狀態(tài)，因而無(wú)法從本質(zhì)上體現(xiàn)輸電元件熱載荷狀態(tài)以及輸電元件溫度變化對(duì)潮流的影響，易導(dǎo)致電網(wǎng)運(yùn)行分析結(jié)果的保守或冒進(jìn)。針對(duì)該問題，本程序在輸電元件在線監(jiān)測(cè)技術(shù)實(shí)施的基礎(chǔ)上（如DTR，DTS等），將輸電元件電熱耦合規(guī)律與電網(wǎng)潮流規(guī)律有機(jī)結(jié)合，基于配電網(wǎng)計(jì)算的前推回代法構(gòu)建計(jì)及電熱耦合的配電網(wǎng)潮流計(jì)算方法。其核心在于將輸電元件（包括架空線路及電纜線路）熱平衡方程與電網(wǎng)潮流方程聯(lián)立，以電阻-溫度效應(yīng)為紐帶，將潮流計(jì)算的前推回代過(guò)程與熱平衡方程求解交替進(jìn)行，進(jìn)而實(shí)現(xiàn)熱穩(wěn)態(tài)平衡及動(dòng)態(tài)平衡下的溫度計(jì)算，在此基礎(chǔ)上，通過(guò)仿真對(duì)比分析了潮流計(jì)算方法對(duì)網(wǎng)損分析以及安全分析結(jié)果的影響。算例分析表明，通過(guò)此研究工作可使配電網(wǎng)潮流計(jì)算更加貼近真實(shí)，且能夠幫助調(diào)度實(shí)現(xiàn)以溫度把握輸電元件熱載荷狀態(tài)，對(duì)提高配網(wǎng)潮流計(jì)算精度，以及充分利用輸電元件載荷潛力具有重要意義。
