2×300MW机组一次调频程序优化

Program Optimization of Primary Frequency Regulation of 2×300 MW Unit

只要是在电网中并列运行的机组,任何时候汽轮机的转速都是同步的。当电负荷改变,引起电网频率变化时,电网中全部并列运行的机组均自动的按其静态特性承担一定的负荷变化以减少频率的改变,这种功能就叫做一次调频。从巴蜀江油燃煤发电有限公司2×300 MW一次调频的原组态设计和优化后组态,进行详细的对比分析。

The rotational speed of steam turbine which is in parallel operation of power grid must be synchronous with the frequency of power grid at any time. The grid load changes, then the frequency of power grid will change, so the load rate of all turbines in paral- lel operation will be regulated automatically in the rules of their static state characteristics to keep the frequency steady. It is called primary frequency regulation. The detailed comparison and analysis between the former configuration of primary frequency regulation and its configuration after optimization are carried out based on 2× 300MW generating units of Sichuan Bashu Jiangyou Ranmei Power Generation Co. Ltd.
