摘要

汽轮机的高、中、低压缸以及再热器的控制特性时间常数和调节(汽)阀的开启与关闭方向的时间常数是汽轮机及其调节系统模型参数辨识的重点。介绍了现场测试这些参数的方法并对分宜电厂8号机组进行了实际测试

最后根据现场实测结果

得出了8号机组电网稳定性计算模型参数辨识的计算结果。

Abstract

The time constants for control characters of high

intermediate

and low pressure cylinders in a steam turbine

and that in the reheater

as well as the time constants in opening and closing directions of the governing steam valve

are key points for identifying parameters through the steam turbine and its govenor system model.The test methods in the field for these parameters have been presented

and the practical test for unit no.8 in Fenyi Power Plant being carried out.Finally

on the basis of actually measured results in the field

the calculation result for identifying parameters through the power grid stability calculating model for unit no.8 in Fenyi Power Plant has been obtained.
