VOLTAGE INVERTER CONTROL METHOD IN ELECTRIC ENERGY ACCUMULATION SYSTEMS WITH SHARPLY ALTERNATING LOAD Russian patent published in 2020 - IPC G05F1/66 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and power electronics, can be used in designing systems in which to increase power supply continuity, stabilization of source loading level, reduction of power consumed from reactive power source, electric energy accumulator based on voltage inverter and storage battery is used. In the disclosed method, polarity and load power variation in two orthogonal projections are determined, polarity of variation of load power is recorded in two orthogonal projections, multiplying the load power polarity signal in two orthogonal projections by the signal from the comparator of the feedback signal comparison output according to the corresponding orthogonal projection of the voltage inverter power and the setting signal to the minimum level of the given power component of the inverter, multiplied by reference by power supply power variation rate in two orthogonal projections, forming a linearly varying task for the power supply power in two orthogonal projections, calculating error value between feedback signals and power supply power setting signals in two orthogonal projections, generating current setting signals in load circuit in two orthogonal projections, calculating error value between feedback signals and current setting signals in load circuit in two orthogonal projections, converting control signals of orthogonal projections into three modeling signals in time domain, generating a reference bipolar signal, generating pulses for controlling voltage inverter gates when the simulation voltages exceed the reference voltage.

EFFECT: proposed method provides linear variation of instantaneous power of power supply in two orthogonal projections at constant rate of change of load power.
