甩负荷试验是新建机组上网运行的必备条件。本文介绍了天津陈塘庄“二拖一”燃气一蒸汽联合循环发电供热机组的甩负荷试验，试验结果合格。对蒸汽轮机甩100％负荷试验中出现的主蒸汽压力变化较大、甩负荷后蒸汽轮机异常跳闸等问题进行了分析，提出了相应的解决方案。
甩負荷試驗是新建機組上網運行的必備條件。本文介紹瞭天津陳塘莊“二拖一”燃氣一蒸汽聯閤循環髮電供熱機組的甩負荷試驗，試驗結果閤格。對蒸汽輪機甩100％負荷試驗中齣現的主蒸汽壓力變化較大、甩負荷後蒸汽輪機異常跳閘等問題進行瞭分析，提齣瞭相應的解決方案。
솔부하시험시신건궤조상망운행적필비조건。본문개소료천진진당장“이타일”연기일증기연합순배발전공열궤조적솔부하시험，시험결과합격。대증기륜궤솔100％부하시험중출현적주증기압력변화교대、솔부하후증기륜궤이상도갑등문제진행료분석，제출료상응적해결방안。
Load rejection test is requirement for newly constructed plants running on the power grid.This paper introduced the load re-jection test for 2GT+1ST gas-steam combined cycle thermal power plant in Tianjin Chen Tang Zhuang, the results are reasonable.The problems appeared in the 100%load test of the steam turbine, such as the changes in the main steam pressure, and the tripping of the turbine etc., which have been analyzed, and the solutions were proposed.
