Structural and parametric synthesis of anti-average control algorithms for realizing adaptive frequency operating automaticselectrotechnical systems

Abstract

In the event of accidents in power systems associated with a reduction in frequency in order to prevent the complete repayment of the energy district and accelerate the elimination of the accident, frequency division automatics (FDA) are used. Existing technical solutions for the implementation of the FDA do not always provide a balance of the generated and consumed power under the action of the FDA, since the current circuit-mode situation is not taken into account. The aim of this work is to develop effective algorithms for the functioning of adaptive FDA, which allocates power units of a power plant to a balanced load of an isolated energy district, taking into account the current circuit-mode situation. To achieve this goal, we use the method of structural and parametric synthesis of emergency control algorithms, which consists in creating a composite algorithmic model of adaptive FDA. The result of this work is the developed algorithmic model of an adaptive FDA of a power plant, consisting of input and processing algorithms for input analog signals of a FDA, algorithms for input and processing of input discrete signals of a FDA, algorithms for generating start-up organs of a FDA, algorithms for allocating a power plant to a balanced load of a power district. The proposed algorithm for the functioning of adaptive FDA is universal and allows you to automatically allocate power units of a power plant to a balanced load of an isolated energy district, regardless of the type of accident and its cause, the configuration of the electrical network and the values of electricity generation and consumption, as well as the current circuit-mode situation.
