求翻譯:1) 本次計算中,斷面1和斷面2的N-1熱穩(wěn)極限均高于暫穩(wěn)極限,各自輸電能力的主要限制條件相同,都是A區(qū)受電站a1向區(qū)內的送出線路故障跳閘時造成A區(qū)部分發(fā)電機組失去暫態(tài)穩(wěn)定。從實際電網(wǎng)的分析可知,當斷面1傳輸功率增加時,a1站的運行條件也隨之惡化,限制B區(qū)向A區(qū)的送出功率;而a1站送出側500KV線路與220KV線路形成電磁環(huán)網(wǎng),發(fā)生故障或線路無故障跳閘后,傳輸功率大量轉移,極易導致系統(tǒng)失穩(wěn),成為電網(wǎng)的薄弱環(huán)節(jié),限制了斷面2的功率增長。是什么意思?![]() ![]() 1) 本次計算中,斷面1和斷面2的N-1熱穩(wěn)極限均高于暫穩(wěn)極限,各自輸電能力的主要限制條件相同,都是A區(qū)受電站a1向區(qū)內的送出線路故障跳閘時造成A區(qū)部分發(fā)電機組失去暫態(tài)穩(wěn)定。從實際電網(wǎng)的分析可知,當斷面1傳輸功率增加時,a1站的運行條件也隨之惡化,限制B區(qū)向A區(qū)的送出功率;而a1站送出側500KV線路與220KV線路形成電磁環(huán)網(wǎng),發(fā)生故障或線路無故障跳閘后,傳輸功率大量轉移,極易導致系統(tǒng)失穩(wěn),成為電網(wǎng)的薄弱環(huán)節(jié),限制了斷面2的功率增長。
