摘　　要：对汽轮机滑压运行理论进行分析,通过汽轮机调节阀节流程度试验的方法,找到滑压运行的初步阀位,然后在初始阀点附近选取不同阀位进行变负荷试验,验证初始滑压阀位的正确性。该方法适用于工程实际的需要,能减少试验工况点,提高滑压优化试验效率。Based on analysis of the sliding pressure operation theory of steam turbines, an initial valve position of sliding pressure operation was found by throttling tests on the regulating valve, and then variable load operation tests were conducted at different valve positions near the initial point to verify its correctness. This method is applicable to actual engineering projects, which could help to reduce the number of test points and improve the efficiency of sliding pressure tests.
