| 摘 要： | 针对300 MW机组给水泵原有调速方式落后的问题,拟对其进行改造,根据不同负荷、不同调速方式对经济性影响的分析,由液力偶合器分别改为汽轮机调速或变频调速。分析结果表明,这两种改造的方式均能提高上网电量或降低供电煤耗,但采用变频调速更好。

| Abstract: | In view of the behindhand question of original speed governing mode for 300 MW units,it is intended to make retrofit.Based on the analysis of economy influence on different load and speed governing manner,the turbine speed governing or adjustable frequency speed governing is changed from the hydraulic coupler.The result of analysis indicates the manners of two retrofits can increase the network electric quantity or decrease the coal consumption of electricity supply,but the use of adjustable frequency speed... |
