一次调频功能对火电机组运行适应性的试验分析

Adaptability of Primary Frequency Modulati on to Operation of Thermal Power Generating Set

根据铜陵电厂3号机组一次调频功能的试验情况,分析机组在几个不同的典型工况下,一次调频响应能力、特点及进行一次调频对机组安全性与稳定性的影响,确定能满足机组参加电网一次调频的最优运行与控制方式。通过对不同控制方式下全省联调试验数据分析,指出在CCS、DEH调频功能均投入的控制方式下,机组参加一次调频功能的负荷响应较快,功率波动不大,有关指标满足性能要求。

The responsibility and characteristics of primary frequency modulation under different typical operating conditions,and the effect of prima ry frequency modulation on safety and stability of power generating sets are ana lysed,and optimum operation and control conditions are established for primary frequency modulation of power generating sets. It is concluded from the analysis of test data obtained through across-the province coordinated modulation under different control modes that CCS and DEH frequency modulation functions are all put under the control modes,the load response of power generating sets is fairl y fast during primary frequency modulation,the fluctuation in power is not much ,and all the relevant parameters are in compliance with the performance requirem ents.
