Abstract

Wind power and other new energy connected to power grid bring new challenges to optimal operation of power systems. The stability of power grid mainly depends on primary frequency compensation and secondary frequency compensation of thermal power units. But thermal power unit common have extraction conditions. In the analysis of thermodynamic system of thermal power unit, the relationship between thermal power extraction steam and unit's load has analyzed and calculated. The practical application results show that extraction affecting power capability of the unit, is not conducive to adjust the grid frequency.
