摘要
介绍了燃气轮机改联合循环发电的汽轮机热力性能试验,给出了试验方案、计算方法、修正方法和试验不确定度计算方法,分析了试验结果,提出了优化试验方案的建议。通过试验得出:热耗率总不确定度为±0.420,发电机功率总不确定度为±0.355%,表明了该试验方案能够保证试验结果的准确、有效。
Steam turbine performance test of a gas turbine unit expanded to combined cycle is introduced. Test program, calculation method, correction method and test uncertainty calculation method are given. The test is analyzed and recommendation for optimizing the plan is presented. It is obtained though the test that the total uncertainty of heat rate is ±0.420 and the total uncertainty of generation output is ± 0. 355%. It is showed that the test program can ensure accurate and valid results.
