汽轮机及其调节系统参数测试结果异常原因分析与处理

Problems Analysis and Processing in Parameter Test of Steam Turbineand Its Governer System

东源科技有限责任公司热电厂汽轮机及其调节系统参数测试及仿真结果存在异常,实测功率曲线与仿真功率曲线偏差较大,各项考核指标不能满足相关标准规定的误差要求。通过分析试验原始数据及仿真结果,认为导致试验结果异常的原因为控制参数设置及执行机构调整不合理。对机组控制参数及设备特性进行相应的调整后重新进行了现场测试及实测数据辨识仿真,结果表明,主要考核指标均满足有关标准要求,仿真曲线与实测曲线能够较好地拟合。

The testing and simulating results of a steam turbine and its governingsystem were abnormal. The measured power curve and simulation power curve deviationwas large, and the assessment indicators could not meet the requirement of the standards.By initial experimental data and the simulation results, this paper pointed out the cause ofthe abnormal test results. By adjusting from two aspects of control parameter settings andactuator targeted, the simulation results could meet the requirements of the rules, thesimulation curve and the measured curve could be fitted well.
