該(gai)項(xiang)(xiang)目位(wei)于(yu)(yu)河(he)北(bei)省邯鄲(dan)市涉縣經濟開發(fa)(fa)區國能(neng)河(he)北(bei)龍山(shan)發(fa)(fa)電(dian)(dian)有限責任(ren)公司廠區內(nei)，項(xiang)(xiang)目系統應用(yong)于(yu)(yu)國能(neng)河(he)北(bei)龍山(shan)發(fa)(fa)電(dian)(dian)有限責任(ren)公司1號600MW亞臨界火(huo)電(dian)(dian)機組(zu)，采用(yong)抽汽蓄(xu)(xu)能(neng)系統進行深(shen)度調峰(feng)，調峰(feng)能(neng)力按約17%主機額定功(gong)率，即(ji)100MW左右設(she)計，儲熱調峰(feng)時(shi)間暫按每(mei)天4小時(shi)考(kao)慮；抽汽蓄(xu)(xu)能(neng)放(fang)熱時(shi)間暫按每(mei)天6小時(shi)全部放(fang)空考(kao)慮，機組(zu)跟蹤AGC調頻性能(neng)在(zai)現有基礎上提高1.5倍。

據了解，該項目總(zong)投資3.2億元，占(zhan)地面積約6300平(ping)方米，是國內(nei)首(shou)個利用熔(rong)(rong)鹽大規(gui)模(mo)儲(chu)(chu)熱(re)(re)(re)實現機(ji)組(zu)深(shen)度(du)調(diao)峰(feng)(feng)及頂峰(feng)(feng)的重大科(ke)技(ji)創新示范項目。項目采用多源抽汽(qi)(qi)-配汽(qi)(qi)調(diao)控技(ji)術(shu)，可實現最低5%額定負荷(he)上(shang)網，為國內(nei)最低；新增一套(tao)含低溫熔(rong)(rong)鹽罐、換熱(re)(re)(re)平(ping)臺(tai)、高(gao)溫熔(rong)(rong)鹽罐等(deng)構建(jian)筑物在內(nei)的抽汽(qi)(qi)熔(rong)(rong)鹽儲(chu)(chu)熱(re)(re)(re)系(xi)統(tong)，在機(ji)組(zu)深(shen)度(du)調(diao)峰(feng)(feng)期間(jian)抽取鍋爐中過(guo)量蒸汽(qi)(qi)并加(jia)熱(re)(re)(re)熔(rong)(rong)鹽，將熱(re)(re)(re)量儲(chu)(chu)存起(qi)來，非(fei)調(diao)峰(feng)(feng)期間(jian)存儲(chu)(chu)的熱(re)(re)(re)量，根據電(dian)網需求再(zai)返(fan)送汽(qi)(qi)輪機(ji)組(zu)發電(dian)，通過(guo)能量的存儲(chu)(chu)和轉換，改變運行機(ji)組(zu)在峰(feng)(feng)、平(ping)、谷時段(duan)的負荷(he)結構，增加(jia)火電(dian)機(ji)組(zu)的調(diao)峰(feng)(feng)靈活性。
