Abstract

The basic principle of primary frequency regulation of DEH is described as well as the implementation of primary frequency regulation test.The importance of putting primary frequency regulation into service is emphasized for the safety and stability of the system.How to set the reasonable parameter is presented to overcome the grid frequency exceeding the limits due to the units or other causes

to increase and decrease the load quickly by adjusting the opening of regulating valve of steam turbine and to meet the requirement of fast response of grid frequency

which can compensate the load shortage of power grid and guarantee its safety and stability.
