Accelerated Limitation of Frequency Reduction and Increase in Frequency in Small Power Systems

Abstract

The article is devoted to the issues of preventing shutdowns of generating equipment, in particular, gas piston units (GPU) in low-power power systems (LPPS) during active power gains/resets. A review of management and decision-making methods for preventing emergency shutdowns of power units at a power plant with its subsequent repayment, large frequency deviations in low-power power systems is carried out. The simulation of the automatic speed controller of the LPPS station is performed and its effect on frequency control in case of an imbalance of active power is considered. The requirements are substantiated and the algorithm of a special queue (express) of automatic frequency unloading (SQ AFU) is proposed.
