CONTROL CIRCUIT FOR CONTROLLING INVERTER CIRCUIT, INVERTER APPARATUS INCLUDING THE CONTROL CIRCUIT, ELECTRIC POWER SYSTEM INCLUDING THE INVERTER APPARATUS, AND CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method capable of solving problems generated when using a monitoring apparatus in an electric power system configured by connecting a plurality of inverter apparatuses in parallel and capable of adjusting a suppression amount of output effective power of each inverter apparatus.;SOLUTION: A control circuit 3 includes: an input voltage control part 31 for generating an effective power compensation value for controlling an input voltage; a connection point voltage control part 32 for generating a connection point voltage compensation value; a cooperation correction value generation part 33 for generating a correction value for cooperation; a PWM signal generation part 37 for generating a PWM signal on the basis of a value obtained by subtracting a correction compensation value ΔId_i^* obtained by adding the correction value to the connection point voltage compensation value from the effective power compensation value; a weighting part 38 for weighting the correction compensation value ΔId_i^*; and a communication part 39 for performing communication. The communication part 39 transmits a weighted correction compensation value ΔId_i' to the other inverter apparatus A, and the cooperation correction value generation part 33 generates a correction value using an arithmetic result based on the compensation value ΔId_i' and a compensation value ΔId_j' received by the communication part 39.;COPYRIGHT: (C)2015,JPO&INPIT
