Analysis on Primary Frequency Regulation Function Tests for Thermal Power Units

Abstract:

With the increase of the load capacity and the development of the automation degree, the power dispatching center has a higher requirement for the primary frequency regulation function of the unit aircrew. After a certain period of time when the unit has been put into operation, the primary frequency regulation function must have the conditions to be put into operation, so that the unit can be involved in grid frequency at any time when the conditions are satisfied and the power supply quality can be fully guaranteed ^[^1]. The regulation performance of primary frequency regulation plays a vital role in maintaining the stability of the unit aircrew and the power grid, so it is very necessary to conduct the frequency tests for the thermal power units^[2]. In this paper, we describe the disturbance tests and recovery tests under different load points and different network frequencies. Through the analysis, we can draw the conclusion that the primary frequency regulation function of unit 1 can fully meet the requirement of the frequency regulation of the power grid.
