<P>PROBLEM TO BE SOLVED: To provide an electric power conversion system capable of facilitating appropriate calculation of the operation amount of an inverter when a gate block is released. <P>SOLUTION: The electric power conversion system, which is connected to a power system, converts DC power into AC power and outputs the DC power to the power system, includes: an inverter that executes the conversion operation according to an input gate signal; and a controller that calculates the operation amount of the inverter using detection information of system power and transmits the gate signal generated based on a result of the calculation to the inverter. The controller includes: a system state determination section that determines generation of a momentary voltage drop; a gate block section that allows a gate block for shutting down an output of the inverter according to a determination result of the system state determination section; and an initializing section that initializes a parameter on the calculation of the operation amount when the gate block is released. <P>COPYRIGHT: (C)2013,JPO&INPIT |
