凝汽器真空对机组调频能力及调节系统动态特性的影响

Effect on the Ability of Unit Frequency Modulation and the Dynamic Characteristic of Regulative System by Condenser Vacuun

通过分析和计算凝汽器真空对机组一次调频能力和汽轮机调节系统动态的影响 ,主要研究了真空变化后静态不等率和转子时间常数的变化。更加全面、总体地看待凝汽器真空变化对机组经济性。

After analyzing and calculating the Effect on the Ability of Unit Frequency Modulation and the Dynamic Characteristic of Regulative System of the turbine by Condenser Vacuum,this paper does main research on the change of static different ratio and temporal constant of rotor when the vacuum changes.The effect on the economic characteristic,security and modulation capability are looked on more roundly when the condenser vacuum changes.
