FIELD: physics.
SUBSTANCE: invention relates to automatic systems with feedbacks for control of electrical values, namely, to system for automatic optimum adjustment of parameters of distribution of unscheduled power setting on the side of centralized and central coordinating systems for automatic control of frequency and power between control power plants participating in automatic secondary control, and can be used to determine coefficients of share participation of power plants in implementation of unscheduled power tasks. Proposed method of distributing control actions between power plants participating in automatic control of frequency and active power flows, it is characterized by the fact that each second generated unscheduled task is distributed between control power plants in accordance with coefficients of share participation. When the topology of the electric network is changed, the coefficients of share participation are first determined as values proportional to the values of available reserves of regulating power plants obtained from the electric power system. Then values of coefficients of share participation are selected from a predetermined set of the best coefficients of share participation under condition of achievement of control objectives. Further, with unchanged topology of the electric network, optimal coefficients of share participation are selected from all possible combinations thereof according to the condition of achieving control objectives. Achievement of control objectives is controlled by changing the output power of the control power plants by the value of control actions in the reference mode, formed on the basis of values of voltages, currents and power flows obtained from the electric power system, or in the calculated model, which is previously formed on the basis of the reference mode with the corresponding topology of the electric network.
EFFECT: wider range of technical means for distributing control actions between power plants participating in automatic control of frequency and active power flows.
