描述
熱力站控制系統(tǒng)根據(jù)各系統(tǒng)的實際情況,設(shè)定一個供回水壓差目標(biāo)值。設(shè)定此供回水壓差值以滿足二次管網(wǎng)的供暖水循環(huán)。在此基礎(chǔ)上,熱力站PLC系統(tǒng)通過測量二次網(wǎng)供回水溫差來對循環(huán)泵進(jìn)行修正。當(dāng)二網(wǎng)供回水溫差偏大時,則需提高循環(huán)泵轉(zhuǎn)速,加大二網(wǎng)流量,提高二網(wǎng)回水溫度,改善供熱效果;當(dāng)二網(wǎng)供回水溫差過小時,需適當(dāng)降低循環(huán)泵轉(zhuǎn)速,減小二次網(wǎng)的流量,實現(xiàn)小流量大溫差的運(yùn)行模式。這種調(diào)整可以起到節(jié)約電能及熱能的效果,在大型熱網(wǎng)中,這種節(jié)能手段就能取得可觀的效果。
